How to increase engine power: options for gasoline and diesel engines. The main ways to increase the power of a car engine How to increase engine power with improvised means

01.12.2021

Car selection

Many motorists are interested in how to increase the engine power of their own car. Some dream of high speeds, others are fans of sports hobbies. There are many options to increase power while maximizing speed. The difference between them is in price and performance.

However, it is worth remembering that more power makes the car more "gluttonous", and this does not suit everyone. Therefore, making such a decision, you should carefully analyze each method separately, drawing the appropriate conclusions.

Power addition options

Reducing vehicle weight

To do this, heavy parts are replaced with analogues made of light, but very durable material. This method allows you to reduce fuel consumption, improve handling, increase dynamics. But, to the question of whether it is possible to improve engine functions thanks to it, the answer is unequivocal - no.

We install a filter with zero resistance

The most simple and inexpensive method applied to sports cars. The filter has maximum cleaning capacity and does not resist the passage of air. This speeds up its access to the combustion chamber, contributing to the efficient use of gasoline and a significant increase in engine power.

Thanks to the ability to carry out cleaning, the filter does not need to be replaced, which can significantly save the budget. True, this method does not allow to achieve a significant increase in power.

This is a really effective option that requires minimal investment. It consists in increasing the volume of the block cylinders by boring. Due to this, the connecting rods, as well as the pistons, are subject to changes.

This technique does not guarantee that the increase in power will justify the expected result. It is possible that with minor changes, fuel consumption will increase quite impressively.

We install sports counterparts to standard parts

Thanks to forged pistons, it is possible to significantly increase the load on the engine. Such an increase in engine power provides an opportunity to achieve the expected results, squeezing the maximum out of any unit.

But, at the same time, you will have to replace the brakes and the gearbox (gearbox), which need to be adapted to new loads. The advantages of this technique include maintaining fuel consumption within the same limits, as well as increasing the operating period due to the use of quality parts.

ECU reprogramming (electronic control unit)

Almost all cars with injection engines are equipped with a control unit with a specific work program. Despite a number of restrictions put forward by the ECU to the specific characteristics of the engine, they can be successfully bypassed.

Programmers have their own way of doing this, allowing them to introduce new parameters into the car's "brain". Thanks to computer technology, such chip tuning gives effective results.

It is not recommended to carry out such a procedure on your own. This can lead to a program failure that can disable the unit. This work should be done by professional programmers!

Replacing the exhaust pipe

Interested in how to increase engine power, it is worth paying tribute to this not quite standard technique. It is able to add about 15% to the maximum power at an insignificant cost, it consists in installing a direct-flow pipe to the exhaust system.

This helps to reduce the resistance of the outgoing gases, which significantly speeds up the movement. Thanks to this, the engine's energy costs for exhaust gases are reduced and redirected to efficient acceleration of the crankshaft. The retribution for such pleasure will be unpleasant noise and too dirty exhaust, polluting the surrounding air.

Installing nitrous oxide

Many filmgoers are familiar with a substance called nitrogen. The cylinder installed in the machine is activated, which gives a significant acceleration. True, not for long. This technique is extremely simple, but the short duration of action and the high cost of the components are a significant drawback.

Ways to increase engine power include installing a turbocharger. Passing through the turbine, the exhaust gases are accelerated by a specialized fan that pumps large volumes of air to the combustion chamber. The stronger the driver accelerates, the number of revolutions will increase faster, which is quite strongly felt.

True, this will have to use a more reliable cooling system. Despite the fact that installing a turbine is quite an expensive pleasure, it will help to significantly increase the potential of the engine with your own hands. The disadvantages include the increased "voracity" of the car.

Despite the seeming simplicity of tuning a gasoline engine, it is advisable to entrust the work to specialists from the car maintenance industry. After all, structural changes in the power unit are a serious improvement that can affect numerous parameters. If performed incorrectly, there is a risk of accelerated wear of the chassis, as well as the transmission.

Speeding up a diesel engine

From gasoline engines, diesel engines are fundamentally different in the technology of combustion of mixtures, which are first set on fire with the help of electrical discharges. In diesel engines, the strongest detonation occurs after powerful compression.

This property does not allow applying some of the listed methods to them, since the diesel engine becomes unsuitable for upgrades. Given this, the cost of improvements will be much higher.

The features of the modernization of diesel engines include the following.

All modern diesel units provide for the presence of a turbine in the design. Therefore, modernization consists in replacing it with a more powerful one.
The finalization of the cylinder head, as well as the start-up, is replaced by the installation of improved fuel supply systems, among which CommonRail is quite popular. This is a rather expensive type of tuning, but effective.
Chip is applied in the same way.

Diesel engines with their intake system have more complex devices than gasoline engines. Therefore, you should not expect a super increase in power without a professional engineering approach. However, the cost of the upgrade is so high that many motorists prefer to buy a car with more power.

A budget option

If you wish and have the opportunity to increase engine power, you should turn to the help of professionals in a specialized tuning studio. If you have an equipped garage, you can achieve improvements yourself, but this will require certain knowledge and professional skills.

After all, there is a considerable difference between an old-fashioned penny and a modern expensive car, and without the appropriate skills, you can not improve performance, but harm the car.

If you remember how long ago diagnostics were done, candles, filters, as well as liquid were changed, space investments will not be required to increase power. By cleaning the throttle, checking the compression of the engine, cleaning the intake, you can significantly increase the dynamics of the car by increasing the power. Fuel quality is also of great importance.

Possible consequences

For units that have received changes, the resource is significantly reduced. Therefore, frequent diagnostics and installation of expensive parts will be required. Having compared the desires with the possibilities and assessed the cost of the upcoming modernization, perhaps the best option would be to purchase a new car with a more powerful engine.

Serious improvements entail increased fuel consumption. This should also be taken into account when deciding on tuning.

Probably, every motorist sooner or later wonders how to increase the power and torque of his own "iron horse".

For some, this question arises after numerous modifications of the car: it seems to be hung with all sorts of body kits and looks like a sports car, and “from the traffic lights”, God forbid, at least somehow worthy to move off.

For some, increased power and torque is a matter of paramount importance, on which attention is focused even when choosing a car. However, there is no limit to desires, and the possibilities of an already familiar car are clearly not enough.

Paradoxically, the main and easiest way to increase the power and other speed characteristics of a car is to replace the car with another one that better meets the needs of the motorist.

Despite the obvious simplicity of solving the issue of increasing the speed characteristics of a car in this way, it does not suit everyone.

Someone will have a follow-up question about the availability of the necessary amount of money, someone’s familiar car has become “painfully” native in order to change it, and someone just wants to enjoy the process of gradually “pumping” their car.

In any case, if you want to "speed up" your car without completely replacing it, then this article is written for you.

How to increase engine power using the injector control unit?

Now this is the most popular option for increasing the power parameters of a car, assuming that the installed injector control impulse change unit gains control over the fuel system through the “needles” of the injector.

Such a diesel engine power increaser is mounted in a break in the wires that control the fuel injector.

Due to its operation, the signal is delayed, the injection angle changes, and fuel is saved, since the pulse is so short-lived (no more than 0.0002 seconds) that it is blocked (it is simply not perceived by the block).

Since the pulse changers do not have their own high-voltage stages that can send a signal, they are not able to broadcast non-basic pulses.

Similar blocks manufactured under brands known to Russian motorists GreenBOX, TUNIT, R-Box, TuningBox, BlueBOX, TBS, Power-Box, can be mounted on all types of diesel engines equipped with an electronic injection system.

Their use allows you to save fuel. In addition, the cost of products is more than affordable.

At the same time, the described block for increasing the power of a diesel engine has a number of disadvantages:

Reducing the resource of the internal combustion engine, caused by the fact that the device excludes some fuel supply functions;

Complicated and lengthy installation;

Increased emission of harmful compounds;

The particulate filter wears out very quickly due to the lack of momentum, which is designed to ensure proper combustion of fuel.

Increase in engine power on high-pressure diesel engines

Improving the operation of the motor is achieved by installing a special unit that replaces the operating modes of the fuel pump (TNVD). Suitable for some engines equipped with older pumps (produced before 2008) under the brand BOSCHVP 44.

Such installations are characterized by the fact that in them high pressure is accumulated in the pump, and not in the HP rail.

The increase in diesel engine power is achieved by understating the values \u200b\u200bthat the fuel pressure indicator shows. And this causes an increase in pressure in the pump (in its housing).

All the work is done by a solenoid valve (it controls the pressure). Moreover, it operates outside the nominal modes, which leads to a decrease in the life of the high-pressure pump.

The described increase in diesel engine power has such advantages:

Fast installation;

There is no direct impact on the volume of emissions of harmful elements;

The resource of the cylinder block is not reduced;

The element base is inexpensive and objectively simple.

This block, of course, also cannot do without drawbacks:

Smoke is fixed from the exhaust pipe (it is called after operational);

The resources of the electromagnetic injector and high pressure fuel pump are reduced;

ICE floating revolutions are noted.

How to increase engine power in other ways?

Expensive and complex methods involve internal intervention in the device of the car engine (technical tuning) and require significant time costs for execution and extensive experience of the tuning specialist, as well as very significant financial investments from the customer.

Expensive and complex ways to increase power and torque

At the same time, the difference in the operation of the car engine after the implementation of expensive technical tuning will be very noticeable, but it will also noticeably affect its motor resource.

In the future, the repair of the forced engine will hit your pocket hard, if you manage to find performers at all. Costly ways to increase engine power and torque include:

Installation of supercharging on a naturally aspirated engine

This is the most expensive and complicated way of technical tuning a car, which includes a number of complex activities (supercharger selection, engine boost, manifold modification, testing, etc., etc.).

At the same time, the installation of supercharging can enormously increase both power and torque due to a significant increase in the air entering the combustion chamber. There are two types of supercharging: the most common turbocharging (eng. "turbocharger") and mechanical boosting (compressor, eng. "supercharger").

Engine replacement

Definitely, in order to increase power and torque in this way, the performer's great experience and significant financial costs are required both for a new motor and for its installation, which involves a number of activities: determining a suitable engine for replacement, finalizing the engine compartment, connecting electricians, replacing the computer And so on.

Forcing

It implies mechanical intervention in the engine device: replacing certain of its elements (for example, a camshaft, throttle valve or turbine) with sports ones, as well as boring a cylinder block, which will lead to an increase in engine volume and, accordingly, to an increase in power and torque.

In addition, the engine will become much more demanding on maintenance.

Budget and affordable ways to increase power and torque

There are also less costly and affordable methods that do not involve technical intervention in the engine device.

The main principle of such methods is the elimination of restrictions in the operation of the engine, provided by the manufacturer in order to comply with environmental standards of the car, as well as in order to reduce the number of warranty calls to service centers.

Available ways to increase power include:

Chip tuning

Software optimization of engine operation implies a change in the ECU operation parameters set by the factory by various methods: using electronic modules or by manually adjusting ("firmware") the control unit program.

Electronic modules have a large number of advantages over the ECU "firmware" service, and negative reviews in their direction, as a rule, are not supported by any facts.

At the same time, the latest ProRacing OBD electronic modules are able to automatically, autonomously and safely increase the speed characteristics of cars.

Chip tuning is the most effective budget way to increase power and torque and does not require any technical intervention. In addition, competent chip tuning helps to reduce fuel consumption.

Modification or replacement of the air intake system

This is achieved by installing a zero resistance filter or by completely replacing the standard intake system.

In the first case, the increase in power will be within 2-5% due to a decrease in the resistance of the filter element to the incoming air flow, while in the second case, the increase can be very significant not only due to a decrease in the filter resistance, but also due to an increase in the flow of cold air.

This method deserves detailed study and requires the right approach to implementation, otherwise you can seriously damage the engine or simply not feel the result.

Modification or replacement of the exhaust system

For the sake of ecology, as well as to significantly reduce outgoing noise, the standard exhaust system limits the capabilities of the engine to a certain extent.

Certain measures, such as replacing the catalyst with a flame arrester and removing the particulate filter, will make it easier for the engine to "exhale" and provide a certain amount of additional horsepower and Newton meters. A more expensive, but also more effective way is to completely replace the standard exhaust system with a sports one.

This will give not only a noticeable increase in power and torque, but also equalize the life of the exhaust system with the life of the car as a whole, because. sports exhaust systems are made of high quality stainless steel.

Use of quality consumables

Iridium spark plugs

This method cannot be called tuning, but this does not mean that it should be neglected. The use of high-quality and expensive consumables, such as engine oil, filters, spark plugs, as well as fuel, most directly affect both power and torque.

A separate point is the use of expensive iridium or platinum spark plugs, which greatly affect the operation of gasoline engines and can not only increase power and torque, but also reduce fuel consumption.

There are 2 ways to increase torque and horsepower: chip tuning without interfering with the design of the power unit and boosting the motor with subsequent reconfiguration of the ECU software. Consider how to increase engine power and whether it can be done by hand. Let's talk not only about injection and diesel internal combustion engines, but also VAZ engines with a carburetor.

CHIP TUNING

Changing the software of the electronic engine control unit is ineffective on atmospheric gasoline engines with valve injection. The amount of air entering the cylinders, namely this parameter is important for increasing power, is calculated quite accurately during the design and testing of the engine. Therefore, it is impossible to achieve a significant increase in power by programmatically changing the injection angle, ignition timing, and the amount of fuel supplied. Also, engine chip tuning does not work on older diesels that have a minimum of electronics.

Whether it's modern turbocharged engines. Software adjustment of the moment and angles of injection, ignition, the amount of fuel supplied to the cylinders, a change in the turbocharging algorithm allows you to get an average of 10-15% of the standard engine power.

CAN YOU DO IT BY YOUR HANDS?

Having a technical mindset, a confident understanding of the processes of gas exchange inside the engine, a lot of time and free funds for the purchase of basic equipment, you can do chip tuning yourself. The easiest way is to find a ready-made firmware for your engine model and “upload” it to the ECU. If we are talking about independent software changes, dynamic tuning, then even a practicing diagnostician-auto electrician will need a lot of time to study the issue.

REMOVING ECO-FRIENDLY COLLARS

Physical removal of the catalyst (in the presence of a second lambda probe, it requires a software patch). A serviceable catalyst creates a slight boost to the exhaust gases at the outlet, but in a clogged state, it significantly worsens the filling of the cylinders at high speeds. An even greater loss of power is felt on diesel engines. Particles of soot, mixing with oil vapor, clog the honeycombs of the particulate filter.
Software change in response to the gas pedal. This will not add power to the engine, but the feeling of acceleration dynamics will change for the better.

A change in the intake, exhaust, cylinder head or engine block on injection and modern diesel engines must be accompanied by an online setting. Without changing the ECU software, you will not get a good increase in power and proper engine operation.

THE BASICS OF FORCING THE MOTOR

There are only 5 ways to increase the power of the internal combustion engine.

Lubrication and cooling

A serious increase in power imposes additional requirements on the engine lubrication and cooling system. If possible, it is worth installing an oil pump with increased productivity. If you are going to increase the power of an engine with high mileage, be sure to troubleshoot and, if necessary, replace the oil pump. To prevent overheating of the engine, install an enlarged radiator.

INTAKE AND EXHAUST SYSTEM

The volume of the receiver, the length and flow area of the channels of the intake and exhaust system directly affect the filling of the cylinders. One of the first steps in increasing engine power can be considered the installation of an equal-length exhaust manifold 4-2-1 or 4-1. For maximum performance, it is necessary to install forward flow, but this will increase the noise level. Therefore, for civilian use, we recommend slightly increasing the bore of the exhaust pipe and installing a more sporty muffler. This will reduce the resistance of the exhaust system to the exit of exhaust gases.

Installing a zero resistance filter is one of the most popular ways to increase engine power. Such a move allows you to get no more than 1-3%. Proper installation of the null requires the implementation of a cold air intake, which is implemented from the factory on many cars with standard air filters. Without this, the engine will suck in heated air from the engine compartment, which will worsen the filling of the cylinders and reduce engine performance.

We will not consider the installation of a throttle inlet in detail, since such a method of increasing power can hardly be called civilian.

TURBOCHARGING

For additional injection of air into the cylinders are used:

Which turbocharging system is best for your car depends largely on the engine model, the layout of the engine compartment and the availability of ready-made solutions. For example, for VAZ engines, options for installing both a turbine and a mechanical supercharger have been developed in some detail.

Installation of a turbine or supercharger requires a preliminary reduction in the compression ratio, installation of an intercooler; mandatory transition from DMRV to DBP + DTV. The thermal balance of the engine changes, which requires more performance from the cooling system. To prevent burnout of the pistons and reduce the risk of detonation, pistons with oil nozzles must be installed.

VOLUME, COMPRESSION RATE

The more air-fuel mixture burns in the cylinders, the more power we can get from the engine. You can increase the volume by boring the cylinder and installing larger pistons or by increasing the diameter of the crank. Increasing the travel of the connecting rods leads to an increase in torque at the bottoms. But at the same time, there is accelerated wear of the CPG, since the pistons at the time of shifting exert more pressure on the cylinder walls. Due to the large loads on the CPG, crankshaft, liners, an engine with a large piston stroke cannot be high-speed.

It is desirable to increase the compression ratio only in combination with other engine modifications. But the method will allow you to significantly increase power only on old engines with carburetors, which were designed to work even on AI-86 gasoline. The more the air-fuel mixture is compressed, the more torque can be obtained during its combustion. But keep in mind that the higher the octane number of gasoline, the more expensive it is, and besides, after an increase in power, fuel consumption will certainly increase. Therefore, switching to gasoline with an octane rating of more than 98 for civilian use of a car is simply not advisable.

The use of candles with a low glow number, the operation of the engine on gasoline, the octane number does not correspond to the compression ratio, leads to detonation
Cylinder head tuning
The video shows the basics of refining the cylinder head, which will allow you to increase the power of a naturally aspirated and turbocharged engine with your own hands.

An increase in engine power can be achieved in various ways. Some of them involve software reprogramming or manipulation of the motor itself. All options deserve attention and can be used to refine existing engines. Most of the methods also help to significantly save on fuel and keep the fuel system efficient for a long time. Most often, gasoline engines are modified, but some diesel engines can also be improved by analogy.

Chip tuning

Upgrading the engine with the help of chip tuning is one of the most requested services. The low price of the equipment, combined with its practicality and reliability, make it a leader in its industry. Chip tuning is performed using special instruments that allow you to accurately identify indicators that favorably affect the operation of the engine. If you adjust the operation of the engine incorrectly, this can lead to serious consequences. Among the advantages of chip tuning it is worth noting:

Improved overclocking performance. Such a car accelerates much faster, which is appreciated by lovers of “sinking” the gas at a traffic light.
Power gain. On average, chip tuning allows you to increase the power of the car up to 25%. The indicators depend on the year of manufacture of the car, its model and engine modification.
Increase in speed. Due to the fact that the motor runs more briskly, the car can accelerate 10-20% faster.
Reducing fuel consumption.

Since chip tuning usually affects the performance of the entire car, it will take some time to get used to the new motor. In 2-3 weeks, the driver learns all the new nuances of the engine and gets used to them. After upgrading the engine, low-quality fuel can no longer be poured into the fuel system.

Foreign impurities contained in the fuel can cause serious damage to the power unit.

Increasing the volume of the engine

This procedure involves making changes to the design of the engine itself. The motor is bored and pistons with a large diameter are mounted. It is possible to increase engine power by boring only in specialized services, since a small mistake can cause a complete failure of the motor. Most often, for these purposes, they resort to the services of private traders, but recently such a service has become in demand in certified centers.

The installation of new heads on the cylinder block provides a better air flow, which improves the quality of fuel combustion in the engine. The car starts to behave a little differently, so it may take time to get used to the updated characteristics of the car. For a more harmonious and comfortable movement, you may need to install spoilers or body kits.

If a turbine was not initially installed on the car, then mounting the part will be an excellent solution for a significant increase in engine power. Turbocharged internal combustion engines have a longer service life, but they do not consume as much fuel as conventional ones. The installation of new elements in the fuel system can significantly increase the power of the machine, but at the same time creates an additional load on all parts of the vehicle.

Turbocharged engines are characterized by complete combustion of the fuel mixture in the cylinders, due to which much less soot and products remain inside the engine after the task is completed. Also, turbocharged engines are more environmentally friendly and emit less harmful components.

This is one of the easiest ways, since it does not require alteration of the power unit. Initially, the machine may contain heavy parts that have minimal functionality. First of all, the entire interior is dismantled. After carrying out noise and vibration isolation, there is no need for massive and heavy rugs. Replacing the base seats with sports ones will significantly reduce the weight of the car, but at the same time make the ride more comfortable. Other benefits include:

Manageability improvement. Due to the low weight, the machine is easier to control even in difficult weather conditions. If you install good tires on the car, then the car can easily pass even on difficult soils and deep snow.
Improving patency. Light vehicles move more easily on sand or snow, so outdoor recreation has become more accessible even for small cars.
Improvement of dynamic properties. Dismantling and installation of new elements on the body makes it possible to use natural forces more efficiently.

In general, it is possible to achieve a reduction in the weight of passenger cars by 200-300 kg, but this result may be caused by a decrease in the safety of movement by car.

The part is installed mainly on sports cars, but it can also be mounted in a passenger car. The maximum purification provided by the filter allows air to enter the chamber in the required volume in a very short period. The accelerated entry of air improves the combustion of the fuel mixture and makes the engine more efficient. The increase in power will not be very high, but the advantage of the filter is the absence of the need for constant cleaning.

Practice shows that a direct-flow exhaust system can increase engine power by up to 15%. The main disadvantage of the system is its constant noise. This problem is difficult to get rid of, so drivers who value silence should abandon this type of tuning. An exhaust pipe without a resonator is able to reduce the resistance of the exhaust gases, so that the engine does not waste energy on the output of the gaseous mixture. The released energy is redirected to the crankshaft, due to which it rotates much faster.

Many movies about cool cars mention such a substance as nitrous oxide. The substance burns well, so the engine power on this mixture increases many times over. The installation of nitrous oxide is very expensive, so it is not advisable to use it on passenger cars. Even with the correct operation of the installation, its use is unsafe, so you should not consider the option as a constant gain.

The performance of the unit also depends on which gasoline or diesel is poured into the engine. If the car manufacturer recommends pouring 92 gasoline, then filling fuel under the A95 or A98 brand will significantly increase engine power.

Car refueling should be carried out only in those places where high-quality fuel is poured, which has all the supporting documents.

There are no such divisions in a diesel engine, but refueling at proven stations will allow you to fill in high-quality fuel that will correspond to the declared parameters. In winter diesel there are special additives that ensure the safety of fuel in a liquid state even at a temperature of -20 degrees. There are also other additives that help make the fuel more energy efficient. In the case of a diesel engine, the main thing is not to overdo it with the use of additive formulations.

Where is the best place to refurbish?

Announcements about increasing the power of the car can often be found on billboards, in newspapers, on car service websites. Many small workshops offer to change the engine, but quite often there is a situation when they do not have the right tool or qualifications. Experienced craftsmen will rarely work in small workshops that have a minimum of equipment.

The idea of creating a powerful engine is attractive to many car owners. A strong motor allows you to quickly pick up speed and join the general stream. At any time, if necessary, it is easy to make a dynamic maneuver and leave behind a more expensive foreign car. Such moments give a lot of incomparable sensations.

Engine tuning helps to achieve a significant increase in the dynamics of the car. If you correctly approach this task, it will turn out to reveal the full potential of the motor. This article will discuss how to increase the power of a diesel engine. The described methods help to improve the power unit and achieve real results. But before you start tuning, learn the principles of diesel engines.

How a diesel engine works

fuel mixture. A feature of the diesel engine is the way the mixture is formed and ignited. First, air enters the cylinder, and then the piston compresses it. At a certain moment, fuel is supplied through the nozzle. From the high temperature of the compressed air, it ignites in the cylinder.

Supply system. This is the main link in the diesel engine, which ensures that the required portion of fuel is supplied to the combustion chamber at exactly the right time and with the right pressure. The power supply system is of two types: mechanical and electronic.

Old models of engines were equipped with a mechanical one. A feature of this system is the injection pump, which pumps fuel to the nozzles. The injection power depends on the crankshaft speed. Some of the tuning methods described are not suitable for such engines.

Modern cars are equipped with an electronic power supply system. Fuel is pumped into the rail with the help of a high-pressure fuel pump, and then injected by electromagnetic nozzles. Dosage, pressure and injection timing are controlled by an electronic control unit. By changing its operation, you can easily improve the dynamics of the engine. It is these motors that are suitable for tuning.

The increase in power depends on the quality of combustion of the mixture. High pressure and regulated injection help the fuel burn completely and release maximum useful energy. Due to the balance between the amount of air and fuel, it is possible to significantly increase the power characteristics of the motor.

Diesel engine tuners have several options for improving dynamics: chip tuning, installing a power boost module, turbocharging.

Chip tuning
The easiest way to increase engine power. This method consists in changing the ECU settings. Such a procedure should be carried out by a specialist who has the necessary technical tool and special software for the job.

How is dynamics increased? The electronic fuel supply system is controlled by the ECU. This unit contains a microprocessor that controls the volume of air, injection, crankshaft speed. The ECU interacts with various sensors, receiving information about the state of the engine. Given the data, changes the mode of operation of the power unit. Re-flashing the control unit helps to improve dynamics.

Advantages:

fuel consumption is reduced;
increases the dynamics of the motor;
the maximum speed limit is removed;
the failure in the operation of the internal combustion engine disappears after pressing the gas pedal.

Flaws:

changing the settings will void the warranty if the car is new;
the procedure for flashing the computer is associated with a risk - the consequences are not reversible.

Power increase modules
They are popular means of increasing the power characteristics of a diesel engine. These are special modules that interact with the fuel supply system. They do not interfere with the operation of the computer, but in parallel with it control various electronic sensors. The installation procedure is simple, just follow the included instructions.

There are four types of modules

Module for changing injector control pulses. Controls the activity of the nozzles - slows down or delays the lifting of the needle. As a result, the ignition timing changes, the efficiency of fuel combustion increases, and consumption decreases. The module is connected to the injector wires. Suitable for any diesel engines with a modern fuel supply system.
Module for changing the mode of operation of the injection pump. Interacts with the fuel pressure sensor. Receives information from him and understates the testimony. As a result, the pressure in the pump increases. This allows you to increase the dynamics of the engine without compromising the resource. The module is connected to the wires of the injection pump and the computer. Suitable for diesel engines with a mechanical fuel supply system manufactured before 2008.
Module for changing the readings of the fuel rail pressure sensor. Deceives the ECU, informing him of a decrease in pressure in the fuel rail. As a result, the control unit thinks that the dynamics of the engine has fallen and decides to change the intensity of the injectors. This reduces consumption and increases power. The module is connected to rail pressure sensor wires. Suitable for engines with a modern fuel supply system.
Module for optimizing the operating modes of the central processor unit of the computer. Determines the pressure of the fuel system. If it increases, it sends a signal to the ECU to increase the timing of the injectors. The built-in program corrects the operation of the engine without the help of the ECU. Does not underestimate sensor readings. The module is built into the high pressure system. Suitable for all modern diesel engines.

Advantages of modules:

increase engine power;
reduce fuel consumption;
installed quickly and easily.

Disadvantages of modules:

reduce the resource of the cylinder block;
reduce the service life of high pressure fuel pumps and nozzles;
increase the emission of harmful substances.

Turbine, significantly increases the power of the engine. It pumps a lot of air into the cylinder, and the electronic system increases the amount of fuel supplied. The flow of exhaust gases spins the turbine from low engine speeds. Thanks to this, turbo lags disappear. Motor thrust increases from the bottom.

Diesel engines have a feature - the absence of a throttle. Therefore, air is quickly forced into the cylinders, without the help of complex turbine control systems. In order not to overheat the engine put an intercooler. This device cools the air pumped into the cylinder.

Advantages:

the fuel mixture burns efficiently;
engine power increases significantly.

Flaws:

short service life;
increased fuel consumption;
high cost of a high-quality turbine;
mandatory use of expensive oil and high-octane fuel.

The described methods for increasing the power of a diesel engine will help make the car fast. The easiest way is to install additional modules. But remember that by increasing the dynamics of the engine, you reduce its resource. In addition, fast driving will require additional costs. You will have to spend money on installing reliable brakes. Before tuning the engine, first think carefully about whether you really need this power.
