18 tips on how to reduce fuel consumption on a VAZ 2107

The long-term experience of hundreds of thousands and millions of motorists shows that Russia is a special country. If there is a drop in oil prices in the world, then the price of gasoline also decreases. In the world, but not in Russia. In our country, any change in oil prices leads to higher prices for gasoline on the domestic market. In addition, in recent years, the average car owner has been forced to put up with traffic jams, in which fuel is wasted and equipment wears out.

Therefore, the issue of fuel economy is far from idle.

It is estimated that, depending on the driving method of different drivers in the same car, when driving along the same route, fuel consumption can vary by up to a quarter of the volume, that is, up to 25%.

For example, a trip to the Altai Mountains from Novosibirsk to the Chuyskaya steppe and back (2000 km) under such conditions will bring savings of about 1200 - 1300 rubles, which is absolutely not bad.

The newspaper “Arguments and Facts” presented an interesting infographic on this topic.

Now let’s look briefly at well-known (and not so well-known) ways to save fuel that a driver can adopt. Let’s arrange them in order of decreasing effectiveness and “testing by popular experience.”

Careful and “thoughtful” attitude to the gas pedal

Rationale : everyone can use this method, the less powerful the machine, the more often. The peculiarity of fuel supply at high speeds is that air resistance increases sharply, and, therefore, consumption. “Accelerating” and accelerating from 70 to 90 km/h consumes several times less fuel than from 120 to 140 km/h. Maximum engine power simply devours fuel. Therefore, the most economical speed zone is from 60 to 90 km/h.

Disadvantages : the advice is reliable, universal and has no “cons”

Causes of injector clogging

Typically, problems with the injection system occur when using low-quality gasoline. Heavy paraffins contained in such fuel settle on the walls of the system, cutting off the fuel supply. Manufacturers of high-quality gasoline add a special detergent additive to it that dissolves deposits. Low-quality gasoline contains too much paraffin, which forms deposits faster than detergents can remove them.

Deposits form more intensively at low temperatures, so when the car is frequently driven with a cold engine, the injector becomes clogged more often.

Deposits can accumulate not only in the injectors. Often vapors settle on the throttle valve, which leads to a change in the proportions of the air-fuel mixture entering the cylinders.

Deposits of substances contained in low-quality gasoline may also appear on the back of the intake valve plates. This can lead to valve burnout or fuel detonation.

To clean the injection system of deposits, it is necessary to use special flushing fluid and equipment. You can wash the injector in a garage. To do this, you need a syringe and washing liquid. The latter is mixed with gasoline and poured into the injection system through the hose of the vacuum brake booster. First, the operation is performed with the engine turned off, then with the engine running. The mixture is fed into the running engine gradually, in small portions. As a result, the deposits dissolve, enter the engine cylinders and burn there. In this case, clouds of smoke may briefly appear coming out of the muffler.

Know how to use a gearbox

Rationale : remember a simple formula: in 1st gear start from a standstill, for acceleration there is 2nd gear, for afterburner and overtaking - 3rd, in 4th gear move around the city, and in 5th gear you can switch to the highway. The advice is also universal in nature, but is only suitable for “mechanics”.

Disadvantages : the negative point is a long drive in 5th gear, since, in accordance with the first rule, fuel consumption in it is the highest.

Monitor your engine speed

Rationale : do not allow the tachometer to “dance” when changing gears above 2 thousand revolutions, and change gears earlier, do not “overdrive” before shifting to 3-4 thousand revolutions.

Disadvantages : the advice is universal, but it reduces acceleration dynamics, which is not always acceptable at congested traffic lights. In addition, early upshifts require at least a 16-valve engine.

UOZ

If the OZ is set accurately, all data on the power plant should be normal. This concerns throttle response, power, idle mode and fuel consumption. A strobe light, tachometer and keys with different functions will help you with the setup.

This is how the operation to set the OZ is carried out.

1. The motor warms up to 90° Celsius.
2. The lowest engine speed is set in idling mode. This can be done either using a tachometer or by ear (experienced motorists can do this). The revolutions should be below 800 per minute, but in any case you need to build on the specific readings of the car.
3. Open access to the hatch, from where part of the flywheel is clearly visible. On many cars, the hatch has a scale by which the indicators must be determined.

4. Turn the flywheel with a screwdriver until the long alignment mark is visible. If we correlate the risk with the notch triangle, the SOP will be equal to 0 degrees. In this case, the pistons of the first and fourth cylinders of the engine are at TDC.
5. Connect the strobe light, set the gearbox to XX. Direct the instrument beam at the flywheel scale. The highlighted mark must be clearly opposite a certain division.

You should know that each division corresponds to 1° ignition advance. Along the clockwise movement of the ignition distributor housing, the OZ increases, and against the clockwise movement it decreases. After the required OZ is installed, the motor stops, the device turns off, and the distributor is secured in the desired position.

5. Try never to stop the car completely

Rationale : try to “roll” towards the traffic light in order to accelerate at the green signal when the car has not yet completely stopped. Remember that starting a stationary vehicle consumes the most fuel of the entire cycle.

Disadvantages : the disadvantage of this method is that it is not always possible to accurately calculate the initial speed and the correct trajectory, especially if other road users are involved in your calculation.

Check your tire pressure regularly

Rationale : the lower the pressure, the higher the fuel consumption. At low pressure, the contact area with the road is larger and rolling friction is stronger. If you drive on wheels inflated to 1 atmosphere instead of 2, then you lose an extra 2-3 liters per tank. The advice is good for imported tires, as they hold pressure well, but our domestic Kama needs to be checked weekly.

In case of strong pumping, fuel consumption is noticeably lower, but all the bumps become noticeable, and the ride becomes uncomfortable. And if the pressure reaches 3 atmospheres, then the area of ​​contact with the ground is so small that the braking distance increases quite sharply, which is dangerous. It is even more dangerous to overinflate wheels in winter, when a large area of ​​tire adhesion to the road surface is especially important.

The acceptable pressure range is 2.2 – 2.4 atm.

In addition, you need to regularly monitor the condition of the tire treads. Heavily worn tires increase fuel consumption, including due to lateral deviation from a straight line.

Disadvantages : none

VAZ-2104 – what fuel consumption per 100 kilometers is considered normal

Naturally, speaking about the Quartet’s appetite, specific figures should be given. First of all, it is worth recalling that this model was supplied to the market with different types of engines. Of course, their fuel consumption indicators are different. Generally speaking, during the period when the Quartet was produced, 3 types of engines were installed on it:

• carburetor;
• injection;
• diesel.

However, the latter never became widespread. The cost of a car with a diesel engine was higher than with a gasoline engine, while in terms of power it was slightly, but still inferior to both carburetor and injection engines. As a result, not many of these cars came off the assembly line. The VAZ-2104 was equipped with a 4-cylinder, 8-valve, one and a half liter diesel engine. The power of this power plant is 50 horsepower. Motors of this type are characterized by low fuel consumption. The diesel engine installed on the VAZ-2104 was no exception to the rule.

Engines with carburetors have higher consumption rates, of course. The “fours” were equipped with 2 types of such power plants. The first is the VAZ-2103, 4-cylinder, 8-valve, 1.3 liter. The power of this engine is 63 horsepower. When driving on a city highway, this engine consumes 10 liters per hundred. On the highway, consumption is 6.9 liters.

Another carburetor engine installed on the “four” was the one and a half liter VAZ-2103 power plant. The 4-cylinder 8-valve engine in the city and on the highway consumed, respectively, 9.8 and 7 liters per 100 kilometers.

And finally, injection engines. Two models of such power plants were installed on the Quartet. One of them is VAZ-21073. A special feature of this 1.7-liter 4-cylinder, 8-valve engine is central fuel injection. With a power of 84 horsepower, this power plant consumed 9.5 liters in the city and 7.5 on the highway. However, there are different data on the latter indicator.

The VAZ-21067 engine with a volume of 1.6 liters was also installed on the Quartet. The 4-cylinder, 8-valve power unit with an output of 82 horsepower is quite voracious. In particular, in the city this modification consumes 11.3 liters. Agree, at current fuel prices it’s difficult to call such a car economical. When driving on a country highway, fuel consumption drops to 6.9 liters.

In conclusion, I would like to note one important point. Fuel consumption depends on many factors. Of course, the technical condition of the car plays an important role here. There are many breakdowns with which you can drive for a while, while the car’s appetite increases significantly. In order not to throw money away, you need to eliminate them as soon as possible. In addition, consumption directly depends on driving style. Sharp acceleration combined with active braking increases the vehicle's fuel consumption.

If you want to save money, then you need to give up this driving style. The driving style should be calm, with smooth acceleration and a minimum amount of braking, so that you do not have to pick up speed again. Otherwise, consumption on the “four” is unlikely to be less than 12 liters in the city.

Another important point is the time of year. Probably everyone knows that fuel consumption is higher in winter than in summer. Firstly, before driving off at sub-zero temperatures, it is recommended to warm up the car - and this means additional fuel consumption. Secondly, difficult weather conditions and slippery road surfaces force you to drive in lower gears, which, in turn, increases consumption.

Car insulation

Rationale : during the winter period of operation, a warm garage would be ideal so that fuel is not wasted on warming up the engine. Use special pre-heaters, thermal blankets, and insulating the engine compartment from winter air. Try to set the alarm to “night auto start” as little as possible.

Disadvantages : considerable investment is required, and a good garage can rarely be found near the house.

Advice on the full consumption of the air-gasoline mixture

Rationale : check the spark plug gap in a timely manner, which should be about 1 mm, and also change the spark plugs after a certain mileage of the car. So, many spark plugs need to be replaced after a run of 50-60 thousand km. An obvious “plus” will be the good appearance of the candles, since it is difficult to notice tangible savings from this one rule. Not everyone is able to “throw away” an apparently normally working spark plug, much less the entire set. Many people wait until the candles become unusable. "Human factor".

Disadvantages : small additional cost of money

Race for the leader, or know how to use “low pressure pockets”

Rationale : a very good method when driving behind large objects: buses, tractors in a low-pressure zone - no further than 4 - 5 meters from the “leader”. This method is good for leisurely driving at a constant speed in general traffic, as it allows you to save fuel very well - from 20 to 40%.

Disadvantages : the method is quite dangerous due to non-compliance with the distance, suitable for experienced drivers in certain areas of suburban traffic.

Do not overload the vehicle's on-board network

Rationale : remember that the mandatory low beam alone “eats” more than a liter of gasoline for every 1000 km of travel. Therefore, try to save on winter trips at night. Heater, heated rear window, engine cooling fan - everything increases fuel consumption. For example, when standing closely in traffic jams, the low beams can be turned off and turned on when moving.

A rare button turns on in vain. It is much more important to turn it off in time. Getting carried away, they forget to turn off the heated rear window.

Disadvantages : do not get carried away with this advice in cold weather, it can reduce visibility and create an emergency situation.

Change the air filter promptly

Rationale : the advice is simple and effective, and has no downsides. Just remember that a sufficiently old and dirty air filter can increase fuel consumption by up to 10%. The more loaded the car, the more pronounced is its need to obtain a high-quality mixture. Therefore, every 20-25 thousand km, change the air intake in a timely manner.

Disadvantages : none. Is it just an additional expense of 200 rubles over the course of a year and an extra 5 minutes of wasted time?

If you are confident in the road and weather conditions, use the “coast” when descending

Rationale : when the car uses only idle speed when driving downhill, the fuel savings are quite noticeable.

Disadvantages : the danger lies in the fact that there is no stabilizing drive, especially during sharp braking in neutral gear. But when there is a good road ahead, a minimum of traffic, and a dry road surface, you can use this method.

Damaged or leaking connections in the fuel line: Engine is faulty

EPHH is designed to cut off the fuel supply while the car is moving with the gas pedal released and the gear engaged; it is also called engine braking mode or forced idle. It is not for nothing that the manufacturer indicates in the car manual the recommended ignition timing angle UOZ, since it ensures engine operation in optimal mode.

Do not overuse the lowering of the windows

Rationale : an open window creates a zone of air turbulence, which can slow down slightly, increasing gasoline consumption by 1-2%.

This may not be much, but when there is wind at high speed, other troubles may appear: exacerbation of cervical osteochondrosis (if it blows out) or a cigarette may be “blown out” into the back seat with the risk of a fire.

Disadvantages : in the summer heat on a VAZ 2107, this advice cannot be applied due to the lack of air conditioning in the cabin.

TPS (Throttle Position Sensor)

It is installed on the side of the throttle itself and on the same axis with the throttle valve. Reads readings of opening or closing, respectively, pressing the gas pedal.

At one time there were many fakes that did not last even a month, so you should choose time-tested ones, preferably those that were installed at the factory. There were also cases when they were knocked down or broken by a high-pressure jet at car washes. If these rules are taken into account, they can live quite a long time.

Malfunctions: Dips appear when pressing the gas pedal. Increase in speed (for no reason) at idle. Jerks and dips under load

Cost about 250 – 350 rubles with diagnostics

“Cut” a tight turn

Rationale : if the road situation allows, prepare for the turn in advance and drive it in a straight line, like racing drivers, since a straight line is the shortest distance between two points. The advantage of this advice is that for every 1000 km of a long road, you can save 20 km by maneuvering in this way.

Disadvantages : the disadvantage is that movement must be allowed, and this method must be brought to automaticity, since preparation is needed for the car to hit the desired point before starting the turn, which will allow it to move in a straight line.

Cleaning the float chamber. Carburetor cleaning

In the Soviet era, the 5 was considered a luxury item, and at the beginning of the new century it was the most affordable car, since its cost did not exceed 180 thousand rubles. Solex carburetors are the same technology as other mechanisms in a car, so even with proper operation, it can wear out and eventually fail.

Don't carry a roof rack in vain

Rationale : if you always have a roof rack on your roof, then fuel consumption increases by 10-15%, the same can be said about excess cargo in the trunk. If you carry two jacks, two sets of keys, and always a spare canister with 20 liters of gasoline, a spare generator, an ignition coil, etc., then fuel consumption will increase by 20%.

Disadvantages : once again you will have to install and dismantle the trunk. You need to find a place to store it.

Electric fuel pump

But this is a device that is responsible for ensuring that the required pressure is always present in the ramp. How to reduce fuel consumption will be discussed below. But it is worth noting that the electric pump does not affect this parameter. It is located directly in the tank, combined in a single housing with a gasoline level sensor. It also has a filter. People call it “diaper” due to its external resemblance.

By the way, try to change it as often as possible, otherwise the fuel lines and injectors will become clogged. And cleaning sometimes costs a lot of money. In addition to the electric pump, there is another device that allows you to maintain constant pressure - the regulator on the ramp. With its help, excess gasoline is discharged back into the tank. Therefore, excess pressure for the system is not dangerous.

Choose the right engine oil

Rationale : if you use oil with a reduced viscosity, then fuel consumption decreases as the resistance decreases. Oil viscosity depends on temperature, and it is the loss of viscosity that causes the engine to “seize”

Disadvantages : none

Fuel consumption VAZ 2107

The popular domestic car VAZ 2107 (in common parlance, “seven”) is still successfully used in Russia and is not a type of car that consumes excessive gasoline. Hence the sincere love of the population for this brand. However, there are some concerns that make small car owners nervous. Namely, fuel consumption. Therefore, in this article we will look at the main fuel consumption indicators of injection and carburetor models of the VAZ 2107. We will also discuss how to reduce fuel consumption.

The situation today is such that in the foreseeable future prices for automobile fuel will not decrease. On the contrary, their constant growth is observed. In fact, there is no fixed price in the country for one or another type of gasoline, so the result is a sad picture: the price per liter of automobile fuel can change significantly upward not only at different gas stations, but also greatly depends on the location of the region. Therefore, the current pricing of gasoline is a headache for all motorists, even owners of small cars.

The fuel consumption of any brand of car depends on a set of factors, starting from the most important thing - the type of engine and its condition, to the driving culture in general. But not all motorists know the nuances of safe driving, which results in real fuel savings.
