VAZ 2106 engine installation dimensions. All VAZ cars

In addition, on the VAZ-2106 car, the engine power was increased to 75 horsepower.

In total, three main types of power units were used on the "sixes":

• a 1.6-liter engine, which is a classic model and is used in the vast majority of cars that have successfully survived to this day;
• engine, the volume of which is 1.3 liters. To achieve this indicator, the manufacturer slightly reduced the stroke length of the pistons (by 1.4 centimeters compared to the previous model). In addition, significant adjustments were made to the design of the cylinder block, gas distribution mechanism and camshaft. Finally, a fundamentally new carburetor was used to reduce fuel consumption and improve fuel combustion efficiency;
• carburetor engine with a volume of one and a half liters. Its main design feature is a reduction in the diameter of the pistons, as well as a number of adjustments made to all the main elements of the piston and connecting rod groups.

Unlimited engine upgrade options

One of the key advantages of the motor used in the design of the VAZ-2106 car is the possibility of its modernization. Many domestic craftsmen have found ways to independently raise the power to 110 horsepower by performing the following operations.

"... And instead of a heart - a fiery engine." Of course, everyone knows why the cited work is called "The Song of the Aviators", but in the context of the last 40–50 years, absolute certainty comes that its first verse is about the engines of the VAZ line. Judge for yourself: the VAZ 2106 engine began to be mass-produced back in 1976 on the basis of the VAZ 2103, which, in turn, was born thanks to the 2101, which spun off from the crude Fiat one hundred and twenty-four.

But for various reasons, we are reluctant to part with old things, especially if they have served us faithfully for many years. The assembly of the VAZ 2106 engine turned out to be quite successful. This is confirmed not only by consumer demand, but also by the long period of its production: almost 30 years.

Features of the VAZ 2016 engine

Experienced motorists know the main technical characteristics of this engine: in the classics - gasoline, four-cylinder, cylinder diameter 79 mm, two valves for each cylinder, working volume 1568 cm3, power 75–77 hp. s., torque 3000 rpm, piston stroke 80 mm, compression ratio 8.5 atmospheres, weight 121 kg.

The engine is four-stroke with a carburetor system and an in-line engine, the cooling system has a forced circulation of liquid. Since about 2002, the carburetor began to be replaced with an injector, which somewhat improved the technical characteristics of the engine. Such a “six” scheme is not very common in the secondary market: a lot of problems arise when re-equipping the device, and primarily of a financial nature, although in one and a half to two years of intensive operation of a car, the costs are more than paid off.

It is fair to say that now almost all modern gasoline cars have an injector, but not every motorist will say offhand how an injector differs from a carburetor, although everything is simple.

It is important to remember that although the carburetor is less reliable and more expensive, you can repair it yourself. Repair of the injector, with its greater stability and lower fuel consumption, is carried out at the service station, since diagnostics is possible only if special equipment is available according to the established scheme, and such repairs “weigh” much more expensive. Removing the motor also means fewer problems.

There is also a diesel version of the VAZ 2106 on the market.

Back in 1984, the Bulgarians converted a gasoline engine into a diesel one, while leaving most of the details of the Zhiguli engine unchanged. True, while maintaining the engine size, they failed to maintain its power. The weight of the engine itself has also changed somewhat. There are many pros and cons to this option. However, at the current price for diesel fuel, it is not the best device with a significant alteration.

Six engine: problem areas

Everyone is interested in malfunctions, more precisely, why something is wrong, how to fix it and how much it will cost. It is immediately necessary to make a reference to the fact that the technical characteristics of the VAZ 2106 engine are very similar to 2103 and 2101, which means that the failures of the predecessors are also inherent in the "six".

In general, VAZ engines are “musical”: a knock is often heard, of different intonations and from different places. For example, if at idle with the hood closed you hear a loud knock from the driver's seat, the valves definitely need to be adjusted. By the way, they must be adjusted at least every 7–10 thousand km.

If you hear a metallic sound, you urgently need a service station: the problem is in the piston pins or connecting rod bearings. If the knock looks like ceramic, it's the pistons (you can get to the service yourself). The sound coming from the bottom of the motor when the oil pressure drops says you need a tug - malfunctions in the main bearings.

Incorrect ignition setting, carbon deposits in the combustion chamber or low-quality low-octane gasoline lead to engine knocking, which also disappears after the causes are eliminated. Motorists who have not dealt with Zhiguli before often ask themselves the question: why does the engine smoke? It smokes for various reasons, but if it is strong, the problem is in the oil scraper rings or in the valve seals. If so, there is only one outcome: service station and overhaul.

If you have a carburetor, it doesn’t even matter 2106 or another (their device is the same), it always troit for the same reasons. For example, malfunctions in the ignition system:

• the candle has worked its way;
• the high-voltage wire failed;
• the distributor cover or slider is not in order;
• dampness on the ignition coil insulator, etc.

The engine also stalls with an unadjusted carburetor, if too rich a mixture is captured, if there is excess air in the intake manifold, or if there is no compression in any cylinder. Troit also, if there is a breakthrough of the coolant into the combustion chamber, the cause of which may be a malfunction of the head gasket.

VAZ 2106 (or "six", as the people call this model) is a car that went down in the history of AvtoVAZ due to its wild popularity. The car gained popularity not only because of its quality and unpretentiousness, but also because of the availability of various transformations. For example, the owner has the option of replacing the engine with a more productive one. The main thing is to choose the right power unit for your "six" and correctly install it.

What engines are equipped with VAZ 2106

VAZ 2106 is considered a logical continuation of the entire product line of the Volga Automobile Plant. In particular, the "six" is a modernized version of the VAZ 2103. The sixth model of the Lada was produced from 1976 to 2006.

VAZ 2106 is one of the most massive domestic cars, more than 4.3 million cars were produced in total.

Over the years, the "six" has undergone some changes - for example, the engineers of the manufacturing plant experimented with power units in order to give the car dynamism and power. In all years, the VAZ 2106 was equipped with a four-stroke, carburetor, in-line engine.

Table: engine options

The engines of the sixth model are characterized by the same characteristics as for previous versions: the camshaft is located in the upper part of the device, the rubbing mechanisms are lubricated in two ways - under pressure and through spraying. Lubrication is consumed quite quickly with this method of supply: the factory has set an allowable rate of 700 grams per 1000 kilometers, but in reality oil consumption may be higher.

Oils from both domestic and foreign manufacturers are poured into VAZ 2106 engines, it is important to use the following types of oils:

• 5W - 30;
• 5W - 40;
• 10W - 40;
• 15W - 40.

In working condition, no more than 3.75 liters of oil should be in the engine cavity and in the entire lubrication system of the car. When changing the fluid, it is recommended to fill in 3.5 liters.

The main technical characteristics of the engine "six"

As mentioned above, the VAZ 2106 power unit is the result of a refinement of the VAZ 2103 engine. The purpose of this refinement is clear - the engineers tried to increase the power and dynamics of the new model. The result was achieved by increasing the cylinder diameters to 79 mm. In general, the new engine is no different from the VAZ 2103 engine.

On the Six engines, the pistons have the same design as on previous models: their diameter is 79 mm, while the nominal piston stroke is 80 mm.

The crankshaft was also taken from the VAZ 2103, the only difference was that the crank was increased by 7 mm, which was dictated by an increase in the diameter of the cylinders. In addition, the length of the crankshaft was also increased and amounted to 50.7 mm. Due to the increase in the size of the crankshaft and cylinders, it was possible to make the model more powerful: the crankshaft rotates at maximum loads at speeds up to 5400 rpm.

Since 1990, all VAZ 2106 models have been equipped with Ozone carburetors (before this period, Solex carburetors were used). Carburetor power plants allow you to create a car with maximum vitality and productivity. In addition, at the time of release, carburetor models were considered very economical: the prices for the AI-92 were quite affordable.

All models of "six" carburetors since 1990 have a working volume of 1.6 liters and a power of 75 horsepower (74.5 hp). The device does not have large dimensions: it has a total width of 18.5 cm, a length of 16 cm, a height of 21.5 cm. The total weight of the entire mechanism assembly (without fuel) is 2.79 kg. Overall dimensions of the entire motor are 541 mm wide, 541 mm long and 665 mm high. The VAZ 2106 engine assembly weighs 121 kg.

The working life of engines on the VAZ 2106, according to the manufacturer, does not exceed 125 thousand kilometers, however, with careful maintenance of the power unit and periodic cleaning of the carburetor, it is quite possible to extend this period to 200 thousand kilometers and more.

Where is the engine number

An important identification characteristic of any motor is its number. On the VAZ 2106, the number is knocked out in two places at once (for the convenience of the driver and supervisory authorities):

1. On the cylinder block on the left side.
2. On a metal plate under the hood.

The engine number is assigned at the factory, corrections and permutations of numbers in the number are not allowed.

What engine can be put on a VAZ 2106 instead of a regular one

The main advantage of the "six" is its versatility. Owners of domestic VAZ 2106 cars can tune both the engine and the body with virtually no restrictions.

Domestic options

Power units from any VAZ models can ideally fit the VAZ 2106. However, do not forget that the replacement motor must be of the same size, weight and approximately the same power as the regular one - this is the only way to safely and efficiently change the engine without any alterations.

AvtoVAZ engines can be considered the best options for replacement:

• VAZ 2110;
• VAZ 2114;
• "Lada Priora";
• "Lada Kalina".

The main advantage of such a replacement is the ease of registering a car with a new engine in the traffic police. You will only have to enter a new identification number, since the manufacturer will remain the same.

Engine from a foreign car

To increase the power of the "six", you will have to find more "serious" types of engines. Without changing the engine space in the car, engines from Nissan or Fiat can be installed on the VAZ 2106.

From European ones, the Fiat 1200 ohv engine will stand up as a native. Changes at least.

However, for thrill-seekers, this power may not be enough. On the VAZ 2106, the engine from the BMW 326, 535 and 746 models will easily “get up”. However, it should be borne in mind that with an increase in power, the entire structure of the car as a whole will have to be strengthened. Accordingly, investments will be required to strengthen the suspension, brakes, branches in the cooling system, etc.

Diesel engine on VAZ 2106

It was advisable to install diesel power plants on domestic gasoline cars a few years ago, when the cost of diesel fuel was lower than AI-92. The main advantage of a diesel engine is its efficiency. Today, the cost of diesel fuel exceeds the price of gasoline, so there can be no question of any economy.

However, lovers of increased engine thrust may well install various diesel units on the VAZ 2106. Three rules must be observed:

1. The dimensions and weight of the diesel engine should not greatly exceed the weight of the standard VAZ engine.
2. You can not put engines with a power of more than 150 hp on the "six". without a corresponding alteration of the body and other systems.
3. Make sure in advance that all vehicle systems will be safely connected to the new engine.

Is it worth it to install a rotary engine

Today, only the Mazda concern uses rotary engines to equip its cars. At one time, AvtoVAZ also produced rotary piston engines, however, due to the problematic nature of the device, it was decided to stop equipping machines with such installations.

Installing a Mazda rotary engine on a VAZ 2106 will not allow you to do without intervention: you will need to expand the engine compartment and refine a number of systems. With the desire and availability of funds, all these tasks are feasible, but it is more expedient to install an engine from Fiat, for example, since with a small investment it will give the car the same speed characteristics.

Thus, the VAZ 2106 engine can be replaced both with a similar one from other VAZ models, and with an imported one from more powerful foreign cars. In any case, it is necessary to approach the replacement of the power unit as responsibly as possible - after all, if the connection is incorrect or non-compliance with the recommended rules, it will be unsafe to drive such a machine.

VAZ-2106 is a real classic of the Soviet automotive industry. The car was produced for a long time after the collapse of the Union, which is explained by its incredible reliability. In addition, it stands out from the background of other domestic-made cars with its amazing maintainability of literally every node, the availability of spare parts, and unlimited opportunities for modernization.

An important advantage of the VAZ-2106 is the engine used in this car. This four-stroke unit, equipped until 2002 with a carburetor, and then with an injection fuel ignition system, can run on even the lowest quality gasoline, rarely fails in extreme cold, and can be successfully operated in almost any conditions. Any of its problems are eliminated even without the participation of a specialist - any more or less experienced motorist can easily cope with current repairs.

Engine weight VAZ-2106

On a VAZ-2106 car, the weight of the engine without a gearbox is 121 kilograms. Therefore, this unit is strongly not recommended to try to remove or move alone - this is a direct path to serious injury. It is best to involve an assistant who can insure you during the process of dismantling or installing the motor.

With all the necessary equipment, including both the cylinder head and the ignition system, the engine will weigh even more - 140 kilograms.

Finally, together with the gearbox and the devices attached to it, this value will increase by another 26 kilograms.

As you can see, weight can be quite called a significant drawback of the car in front of imported counterparts. To reduce it, increase power, and also to improve dynamic performance, many drivers today install parts made of light metal alloys.

In 1984, a diesel version of the "six" was released at the Bulgarian automobile enterprise. Replacing a gasoline engine with a diesel-powered engine did not greatly affect the performance of the car. Firstly, the Bulgarians failed to increase the power of the power unit. Secondly, its weight has increased by about 10 kilograms, which can also be called a minus of the alteration.

Other characteristics of the VAZ-2106 engine

The weight of the motor is, although important, but far from its main characteristic. That is why we decided to talk about other features of the power unit installed on various modifications of the Six. For example, engine power on carburetor models was 77 horsepower. After switching to the injector, it dropped to 75 liters. With. However, this parameter can always be increased by carrying out a series of upgrades.

The cylinder diameter of the VAZ-2106 power unit is 79 millimeters, the torque can reach 3000 rpm, the working volume is 1568 cubic centimeters. Finally, the compression ratio of the motor is 8.5 atmospheres, and the piston stroke is 80 millimeters.

Weaknesses of the VAZ-2106 engine

The VAZ-2106 car engine is a modification of the power unit from the Troika. It is quite possible that this is why a number of weaknesses of its predecessors have been preserved in its design. Domestic craftsmen have learned to diagnose engine problems almost by sound. As an example, we give a few symptoms of breakdowns, and also tell you which engine elements could fail:

The VAZ 2106 engine is mounted on passenger cars manufactured by the Volga Automobile Plant, which began operating in 1976. The VAZ 2106 motor is a four-stroke power unit, the circuit is carburetor, the device is in-line.

Design features

The motor is cooled in a closed circuit by means of coolant circulation. The principle of operation of the cooling system is forced.

The scheme of operation of the lubrication system is combined - spraying plus supplying engine oil under pressure.

The order of operation of the cylinders is as follows: 1-3-4-2.

The internal combustion engine device allows for a major overhaul of the VAZ 2106 engine and additional tuning of the VAZ 2106 engine.

The replacement of the VAZ 2106 engine is carried out after familiarization with the new prices for this type of engine. Before proceeding with the replacement of the engine, you need to find out how much the VAZ 2106 engine weighs.

The power unit of the sixth model is installed on VAZ 21074, NIVA, VAZ 2106 vehicles. UAZ vehicles are not equipped with these motors.

15. Tuning VAZ 2106 - horsepower equals 200.

Each engineering revision led to a significant improvement in the design, as evidenced by the presented characteristic of the VAZ 2106 engine.

What has been significantly improved

Improved characteristic of the VAZ 2106:

• The use of a new cylinder block of improved design with a modified diameter.
• The VAZ 2106 engine has increased power due to an increase in the total volume of the power unit and an improvement in the characteristics and properties of the cylinders.
• Use of new gaskets due to changes in cylinder diameters.
• Equipped with pistons with a diameter of 79 mm, borrowed from the eleventh model.
• Ensuring the uniformity of heating of the pistons due to the cylindrical holes in the motor and the use of temperature-controlled steel plates on the pistons.

The special temperature control plates installed in the pistons are made of high quality steel.

2106 Power Package Maintenance

To identify possible problems in the operation of the car, it is necessary to carry out regular diagnostics of the entire machine. With the help of the wizard, the standards for the functioning of all systems of the mechanism are set.

Successful do-it-yourself repair of the VAZ 2106 engine is carried out with certain experience and skills. To help the craftsmen, a special guide book has been released, which can be purchased in the distribution network in stores that sell automotive spare parts.

VAZ 2106 repair, assembly and disassembly are carried out with experience, you also need a complete set of tools and necessary spare parts.

The most common failures of the sixth motor

Car owners most often encounter such defects in the operation of the engine:

1. The inner diameter of the cylinder increases by 0.15 mm after passing more than 5 thousand km. This defect is formed if the engine lubricant is not timely replaced.
2. The camshaft wears out.
3. Noise effects in the form of tapping in the engine. This defect is eliminated by adjusting the valves, replacing the fuel with a higher octane fuel. If these measures did not help, then you need to contact the nearest service station, where diagnostics and repair of pistons and connecting rod bearings will be carried out.
4. Oil pressure drops. In this case, the lubricant does not reach the rubbing surfaces, as a result of which the friction force increases, causing the gaskets to burn out, accelerated wear of the working parts, and the device becomes unusable.
5. Squeaks indicate breakdowns in the timing chain tensioner, damper, or pump bearing.
6. If the engine stalls on the move, it is necessary to deal with the ignition or power systems.
7. Turning off the engine at idle occurs when there is a failure in the idle speed or air damper adjustments.
8. Trouble of the engine, with this defect, it is necessary to adjust or replace burnt valves, cylinder head gasket. The cause of tripling can also be fuel with a low octane rating.

Why is the engine hot

The most common defect in the 2106 engine is overheating. The operating temperature of the engine is before the mark of + 96 ° C.

The reasons that the motor began to get very hot may be malfunctions of the following systems and components:

• thermostat, the occurrence of an air lock;
• radiator, its clogging;
• low quality of the liquid used for cooling;
• the fan has failed.

If overheating of the engine is detected, it is urgent to stop the car and make a thorough examination and eliminate the cause. If the engine starts to heat up due to a broken thermostat, then this device must be replaced with a new one. .

In case of defects in the radiator, it is necessary to allow time for the coolant to cool completely and only after that start diagnostics, draining the antifreeze and repairing the breakdown.

How to boost a VAZ engine

To enhance the power of the motor, various technologies are used. Forcing the VAZ 2106 engine is done using tuning.

The most effective way is to install a turbo on a VAZ 2106 and remove combustion products through a direct-flow system.

VAZ 2106 turbo competes on the road with many famous brands.

Turbine, turbocharging are installed on the improved six in order to modernize it. At the same time, its power increases significantly. Installing special parts inside the power unit does not give the same effect as a turbine.

Vaz 2106 turbo is used by lovers of high speeds. The replaced tuning car has additional equipment that requires additional costs for the care and control of the operation of all systems, for periodic technical inspection. The cost of installation reaches half the price of the machine.
