The first sensations of the car owner after the service on the Mitsubishi Pajero-4 manual transmission 3l.

Gazelle booth(4 * 2 * 2.15), engine 40524 e3 (sewn under e2) cat on the spot, on gas, mileage 120t.km. (at the time of revision), electronic throttle (Simmens). Now running 141t.km., you can sum it up. Significantly improved acceleration performance, the engine began to spin up easier in the range from 3 to 4 thousand. revolutions ( before it seemed like just engine violence), and what surprised and pleased me the most was that 5th gear became absolutely working, before revision, it could only be used on a flat road, without wind, and the speed still fell (it was very infuriating) or from a hill. Now you can safely drive 90-100 km / h on the 5th, drop to 60 km / h and drive or accelerate without switching ( before that it was impossible). Feels like headwinds and climbs became less noticeable. By the way, before completion, the track was 80-90 km / h, now it is 90-95 km / h. .... I live in St. Petersburg (Kupchino), good luck on the roads!!!

UAZ Patriot, 2.7 l., 2009 onwards
Light became on the course and on dispersal. Especially for maneuverability. Became like a good foreign car. The car is unrecognizable, it tumbles in such a way that it is not inferior to any foreign car. Like to ride.

Good afternoon Vladislav. Today I received a parcel with a throttle and immediately installed the assembly. The car is unrecognizable. Volga weighing 1.8 tons from a place tears with slipping over our mountains where I used to go in 3-4 gear now free on the 5th and still going to overclock. At the old node, the speed is 90 km. overclocked at 3000-3300 rpm. Now 2000-2300 rpm. overtaking is fun downshifting is not necessary. And at the same time, I barely press on the gas pedal. So far I'm very pleased with the result.

Best regards, Valentin Borzov (Sevastopol)

I read a lot about throttle tuning and decided to try it. My first impressions - the car became easier to accelerate. Previously, acceleration was from 3000 now from 2000 rpm. already underway. I advise everyone, it really works! Although I had big doubts. And about the fact that many write that this is a scam, do not believe it! First, TRY YOURSELF ... Yes, most importantly, you barely pressed the gas pedal, and the car accelerates briskly. Previously, after releasing the gas, there was a feeling that you were pulling someone in tow and he was slowing you down. ...after releasing the gas in gear, the car continues to move forward confidently. When you next press the gas, the car accelerates confidently without jerking.

Many factors affect fuel consumption. First of all, it is aerodynamics, power and thrust of the engine at low revs, as well as the resistance of the road surface. A lot of energy is spent on acceleration to cruising speeds, but then the force is spent solely on overcoming the resistance of the environment. Therefore, to reduce emissions of harmful substances from the exhaust pipe, environmentalists recommend resorting to a simple mechanism for handling the gas pedal. You can press it only at the start, but after a speed of 30 km / h, light touches are enough. Then the engine will not spin up over 2500 rpm. And this is quite enough for life in the city.

Modern motors have good characteristics on the bottoms. Thanks to direct injection, it is possible to achieve 80% of torque at 1200 rpm. If the engine is also equipped with a variable valve timing system, then 80% of thrust is available even from 1000 rpm. And this means that for a smooth start and acceleration it is not required to gas. By the way, according to the standards of the average European cycle, acceleration to “hundreds” is carried out in 30 seconds, and such dynamics just occurs within the boundaries of 2000 revolutions.

Keeping the engine from over-revving is not easy. If the car is equipped with a manual manual transmission, then you can smoothly release the pedal already at idle, and the engine equipped with electronic injection will raise the thrust a little so as not to stall. The new BMW and MINI models already have a driverless start system. To avoid unnecessary peregazovki electronics itself sets the correct level of fuel supply.

The higher the better

But then you need to reach the highest gear as quickly as possible. At a speed of 30 km / h, it is necessary to turn on the fourth stage, and at 60 km / h, it is necessary to set the “sixth”. Then the engine will spin below 2000 rpm, fuel consumption will drop significantly. For example, at 3 thousand revolutions, 3.5 times more fuel is consumed than at 1500 revolutions.

Thus, driving at a speed of 50-60 km / h in top gear will reduce the consumption of a 1.6-liter engine to 4-5 liters per "hundred". This technique is useful when the fuel level is zero, when you need to reach the nearest gas station with all your might.

In addition, modern cars use the Start-Stop system, which automatically turns off the engine at forced stops. On the "old women" you can turn off the engine yourself. Standing in traffic jams and in front of traffic lights without a working power unit gives a total of another 5% fuel savings. But here we must remember that frequent starts harm the mechanics, and it is better to turn off the engine at stops lasting more than one minute.

Tires and aerodynamics

Well-inflated tires help save fuel. Many manufacturers under standard conditions recommend inflating the “front” to 2.2 bar, and the rear wheels to 2.3 bar. This is the most comfortable pressure for R16 and R17 wheels. But many do not follow the tires for months, allow pressure to be released and forget that the tire sags on a loaded car, increasing the contact patch, which leads to increased wear and increased fuel consumption. Therefore, to travel with the family to the country with a simple belongings in the trunk, you need to increase the pressure in the tires. Each car model and wheel size has its own value. For example, on Focus II with 205/55 R 17 rims, it is recommended to run 2.8 bar in the rear tires. And for the Ford Mondeo, the rear wheels 215/50 R 17 are recommended to pump up to 2.9 bar. Then the contact patch of the wheels with the asphalt straightens to standard values ​​and will decrease by about 1.5 times compared to the minimum pressure threshold. As a result, rolling resistance on asphalt will decrease. And this is about 10% fuel savings. But before pumping the wheels, you need to look at the instructions.

“The pressure recommended for a particular car can be found on special stickers, which, as a rule, are located on the gas tank flap, in the doorway or on the glove compartment,” says Alexey Zayakin, head of the brand promotion and internal communications group at Nokian Tiers LLC. “Following the automaker’s recommendations will have a positive impact on tire performance: grip, hydroplaning resistance, fuel efficiency and tire mileage.”

But most importantly, in order to avoid an increase in fuel consumption, the aerodynamics of the car must not be violated. A roof rack, ridiculous sports body kits and collective farm rear wings can significantly distort the passage of air flow through the car body. Turbulent eddies appear behind the stern, a zone of low pressure is formed, which sucks the car back, preventing its movement. Now all cars are blown in wind tunnels, where engineers try to arrange the body in such a way that the air flow is dumped and chaotic already far astern. The sedan is considered the most optimal body type in terms of aerodynamics.

In general, these simple tips can help save on gasoline. Tests of domestic magazines have shown that, thanks to a set of these rules, it is possible to reduce the consumption of a 1.6-liter naturally aspirated engine in C-class cars with a manual gearbox and front-wheel drive to 3.5-4 liters of gasoline per 100 kilometers. True, driving so economically is a lot of work.

Even car owners who previously did not bother with savings are increasingly looking at consumption figures.

• Do not warm up the engine while the car is parked. On modern cars, even in severe frost, you can start moving immediately after you start the engine. Do not squeeze the maximum out of the engine - thereby you will reduce environmental pollution and the appetite of your car.
• Predict the traffic situation. If approaching a red traffic light, you do not slow down and apply the brake at full speed just before the traffic light, and when the green light turns on, you take off, then you can be seen at the gas station more often than drivers prudently choosing the speed appropriate to the traffic situation.

• Switch off the engine even during short stops. By turning off the engine, for example, in front of railway tracks while waiting for a train to pass, you save money. In some cities, an additional section of the traffic light about the duration of the red signal. The fear of wearing out the starter due to frequent engine starts is unfounded: the engines of modern cars are designed for several tens of thousands of starts.

• Adjust your driving style to suit the terrain. When driving on hilly terrain, you need to make sure in advance that during the descent the car will pick up the right speed and maximum torque to start the next uphill. In this case, the operation of the motor is more efficient.
• Get rid of unnecessary cargo. If you travel with unnecessary luggage, you are losing money. Depending on the car, 100 kg of additional cargo "costs" about 0.7 liters of fuel per 100 km. And such a thing as a full car roof rack can increase fuel consumption by 20%.

• Do not use the conditioner unless absolutely necessary. The operation of the air conditioner in an upper middle class car increases fuel consumption by up to two liters per 100 km. All doctors warn about the danger of catching a cold if the difference in air temperature inside the car and outside exceeds 6 degrees. Driving with the window open slightly reduces the temperature inside the car, but the fuel consumption is higher than with air conditioning and closed windows, not to mention the draft and noise.

The price of autogas at OKKO increased by 20 kopecks/l and amounted to UAH 15.28/l. WOG increased by 14 kopecks/l to 15.20 UAH/l. Also, prices increased by 12 kop/l and 20 kop/l in the AMIC and Glusco chains - up to UAH 14.96/l and UAH 14.70/l, respectively. Now the average price of autogas in the Ukrainian car market is 14.67 UAH/l.

Gasoline and diesel fuel in the AMIC and UPG networks have risen in price by 20 kop./l. BRSM-Nafta increased the price of diesel fuel and A-95 gasoline by 20 kopecks/l. Experts believe that by winter the cost of fuel will increase by UAH 1-1.5, provided no sharp fluctuations in oil prices.

It is well known that owning a car is not only convenient, but also quite expensive. On average, the owner spends about 13-15 thousand rubles a year on the maintenance of a Toyota Corolla. And most of them are for fuel. It is completely impossible to get rid of these expenses / unless, of course, the car is sold /, but at least a little to reduce them - any car owner is quite capable. Today we will just talk about what determines the efficiency of the car and how it can be improved. Moreover, without any alteration of the engine or the machine itself.
So, remember a few simple rules, the implementation of which will allow you to save up to 30-40 percent of fuel.
First, everything that interferes with aerodynamics costs money. These are wide-profile tires not provided by the manufacturer, decorative spoilers, fashionable "muzzles" with ears on the hood, and other trifles that serve only for beauty. Even more fuel consumption is increased by roof racks - even if they are streamlined boxes. And there is no need to talk about traditional metal farms. In a word, everything superfluous - down with it!
How much fuel can you really save by following the rule? Here's an example for you: the Toyota Kaldina family station wagon, popular in Primorye, flies along the highway at a speed of 120 km / h. If three mountain bikes are fixed on its roof, the car will use 12-13 liters of fuel instead of the usual 8 liters. Total - 40 extra rubles for every hundred kilometers.
The second rule is that constantly switched on consumers of electricity also cost money. Hence the moral: turn them on only when necessary. An air conditioner, for example, will cost an extra 800-900 grams of fuel for every 100 km, and an ordinary car radio will “gobble up” about 300 grams. But there is also a rear window heater, headlights, wipers ... Although, you are unlikely to be able to save on the latter. After all, they are included only if necessary ...
Rule three. Do not warm up the engine to operating temperature while standing still. Get moving as soon as possible. Moreover, under load, the engine warms up much faster than at idle.
4th rule - try to exclude from your arsenal "dashing cavalry starts" from a traffic light. Move off without stepping on the accelerator pedal to failure and switch to the next speed as soon as possible. If possible, try to drive in top gear - modern engines, especially diesel engines, pull well in 4th already at a speed of 50 km / h.
Rule 5. The engine should, if possible, run at the speed corresponding to the maximum torque. By the way, it is listed in any automobile directory or catalog, as well as in the technical description of the car. True, if the car does not have a tachometer, then it will be difficult for you to fulfill this requirement. Well, the owners of cars with automatic transmissions can completely ignore it - the machine will do everything itself. The main thing is to gently press the gas pedal, and turn on the economy mode.
Rule 6th. Proportionate and prudent movement saves fuel. Calculate the road situation, avoid unnecessary accelerations and movement "at full throttle". Before the "red" signal of the traffic light, remove your foot from the gas pedal in advance and coast, instead of intensively braking in front of the car in front.
Rule 7th. Check tire pressure regularly. It's better to over-pump them a little than under-pump them. Remember, reducing the pressure by one "atmosphere" can cost you an extra two or three liters of fuel. In addition, insufficient pressure adversely affects the handling and stability of the car, and also harms the tire itself. By the way, if you ride winter or all-season tires in summer, fuel consumption will increase by a liter and a half. Therefore, "shoes" should be in season ...
Rule 8. Running an engine on a parked car costs money. Therefore, turn off the engine in traffic jams and at regulated intersections, if a decent “tail” has gathered in front of the traffic light, and you will have to stand for a long time.
And finally, the last one. Modern energy-saving motor oils - usually synthetic or semi-synthetic - save up to 6 percent of fuel. True, these oils are more expensive than their mineral counterparts. So the economic effect of their use must be calculated for each specific car and driver ...

Causes of increased fuel consumption - some useful tips for a motorist

To the problem of fuel economy: causes of increased consumption

In an era of economic crisis, the problem of fuel economy is becoming increasingly important.

In this article, we will look at the main causes of increased fuel consumption. So, let's begin. According to the advice of experts, with an increase in fuel consumption, the problem should be solved, starting from the smallest.

The first and most elementary is the condition of the car. Some factors that increase the resistance of the car when driving and, as a result, an increase in fuel consumption: overtightened wheel bearings, incorrect alignment, low tire pressure, roof rack.

The second is the quality of the fuel used. For example, gasoline produced from natural gas condensate is consumed in greater quantities. The conclusion is that it is ultimately more profitable to use high-quality gasoline, especially if you take into account possible problems with the repair of the fuel system due to poor quality fuel.

Thirdly, driving style directly proportionally affects fuel consumption. If you like to press the pedal to also sharply apply the brakes at the nearest traffic light, then be prepared to overpay for this joy.

Fourth - the state of consumables. Their timely replacement is necessary, first of all - the air filter. It is not necessary to bring it to a state of extreme pollution. There are people who have owned a car for more than two years and have not changed the air filter (on such a filter, you can safely plant champignons). A dirty air filter is an elementary cause of increased fuel consumption. A similar negative effect can be caused by the use of a low-quality filter.

Fuel consumption can be caused by the condition of the spark plugs/glow plugs, such as incorrect electrode gap. Often candles fit in size, but do not exactly match the technical parameters. Candles should be exactly for your car (in the spare parts catalogs, this data is given very clearly). The use of iridium plugs (due to a slight increase in engine acceleration) gives a slight savings, but mainly it is necessary that the corresponding plugs are all in working order. The same applies to armored wires.

Fifth (very relevant for the Yakut people) - the impact of low temperatures significantly affects the increase in consumption - this is not surprising, because you have to warm up the engine and interior more often, besides, the resistance of automotive components increases somewhat. Therefore, you need to insulate the car (additional windshield, radiator protection, felt or auto-blanket under the hood). It does not interfere with the timely replacement of fluids in the clutch system, brakes. It is recommended to use synthetic oils for the engine, gearbox, axle in winter.

Then there are the problems that specialists can better handle. Let's list the possible ones: incorrect operation of the mass air flow sensor (MAF-sensor), idle solenoid valve, oxygen sensors (lambda probes). The general essence of fuel consumption in the norm is reduced to the optimal ratio of the amount of fuel and the oxygen supplied for its combustion. In other words, when there is not enough oxygen, the engine compensates for power by increasing the fuel, and vice versa, when oxygen is in excess, the fuel supply decreases, but the power also decreases significantly (traction disappears).

Of course, the condition of the fuel system leads to an increase in fuel consumption: clogging of nozzles, throttle (carburetor) channels, fuel pump problems (for example, fuel filter clogging), etc. - in this vast area of ​​​​knowledge, in relation to a single car, specialists often find it difficult). We also note that the general wear of the engine also increases fuel consumption - the lower the compression, the greater the consumption.

In the next publication, we will look at existing methods and innovative developments that reduce fuel consumption - we will check from the point of view of science and practice the claims of manufacturers and sellers of various products.
