How to reduce consumption on a VAZ 2106 carburetor

Fuel quality and octane number

I think many people have noticed that depending on the place of refueling, your VAZ 2106 always consumes gasoline differently. If this has not been noticed, it means you haven’t been driving long enough yet. Everyone encounters low-quality gasoline in one way or another. Another question is how to protect yourself from this?

Well, it’s difficult to give any sensible advice here. Unless you try, if possible, to refuel only in trusted places. But even there, there is outright slag! If you feel that there is surrogate in the tank, then ideally you need to drain all this muck. Well, then refuel with normal fuel. Otherwise, you risk damaging the engine.

Regarding the octane number. Here you should follow the manufacturer’s recommendations and fill in the gasoline that your engine requires. If it says 92, it means we only use it if we want normal consumption.

Condition of the internal combustion engine and fuel system and increased fuel consumption

If the engine of your VAZ 2106 is already pretty tired, and the mileage without repair is already hundreds of thousands of kilometers, then it is possible that the reason for the increased fuel consumption is precisely the loss of engine power. And moreover, it begins to consume excessively not only gasoline, but also oil.

In this case, only engine repair will help solve this problem:

replacing piston rings,
boring cylinders if necessary
replacing the pistons themselves.

Regarding the fuel system. Likewise, it must be in excellent condition so that consumption remains normal. The carburetor should not “flood” or over-supply fuel at idle speed. Adjust the carburetor if necessary.

If you have an injection engine, then the increased fuel consumption may depend on even more factors. Example. The failure of one of the ECM sensors almost always entails an increase in the appetite of your car. This is especially true for sensors such as:

Mass air flow sensor - mass air flow sensor,
TPS - throttle position sensor,
IAC - idle speed controller and others.

We reduce gasoline consumption on VAZ cars

Here are some smart and effective ways to save fuel:

One of the most effective options is to install gas equipment. Propane and methane are cheaper than gasoline.
Change your driving style. In the city you can drive at a speed of 60 km/h, and on the highway – 90 km/h. You should forget about sudden acceleration and braking. As a rule, this helps reduce fuel consumption by 40%.
Installing a pneumatic drive on a carburetor.
Installation of a 5-speed gearbox.
Use light motor oils. It is advisable to use oils with low viscosity, as they save fuel by 6%.
Check tire pressure periodically. If the ramps are underinflated, they increase rolling resistance, which, in turn, significantly consumes fuel. Please note that the check can only be carried out with cold tires.
Maintain approximately the same speed, even in traffic jams. As we said, you shouldn't brake and start hard if you want to reduce fuel consumption.
Use the pedal carefully. A sudden start consumes a lot of fuel, so you need to start the car slowly.
Rarely turn on the air conditioner. This device burns from 5 to 20% gasoline.
Get rid of anything that increases air resistance. This is mainly due to tuning, extra things in the trunk, cargo on the roof, etc. It is also advisable not to change the serial wheels to wide ones.

The following actions will also help save fuel consumption:

Only when absolutely necessary should you use power windows, heated rear windows and interior lighting. By and large, these devices are rarely needed, so their use can be reduced;
replace contact ignition with electronic one. In most cases, this helps reduce fuel consumption;
troubleshoot problems in the ignition system in a timely manner. Approximately 30-40% of fuel can be lost if the ignition system operates intermittently;
Do not brake suddenly. In particular, this applies to carburetor cars, because during sudden braking, a large amount of fuel is sucked through the jets.

So, we looked at the most effective and popular ways to save gasoline. If you are used to driving at high speeds, you will have to forget about this in order to save money. It is also important to follow a number of other rules in order to reduce fuel consumption in your car. It is very important to act without fanaticism, otherwise saving will not lead to anything good.

The VAZ “six” was produced by the Volzhsky Automobile Plant for 30 years, from 1976 to 2006. The car was equipped with carburetor engines with a volume of 1.3 liters to 1.6 liters. Various carburetors were used as part of the fuel system, but the most common was Ozone.

One of the most common carburetors for the VAZ 2106 was Ozone

As you use a car with a carburetor, certain problems may arise that require cleaning, adjusting the unit, or replacing any of its parts. Let's look at the most common problems with the mechanism and methods for eliminating them.

The performance of the power unit under any operating conditions directly depends on the correct adjustment of the carburetor. This suggests that before you pick up a tool and turn any screws, you need to understand which part is responsible for what. In addition, you will need to prepare the following tools:

set of screwdrivers (flat, Phillips);
set of open-end wrenches;
a set of round probes or drills of different diameters;
rubber bulb;
toothpicks;
container for washing the mechanism;
calipers
tweezers;
ruler;
rags.

The reasons for removing a unit can be different: replacement with a product of a different modification, repair, cleaning. In any case, you must first remove the air filter. To carry out the replacement work you will need the following tools:

open-end wrench 13;
crosshead screwdriver;
heads for 8 and 10;
knob;
small extension cord.

From the functional and technical side, fuel consumption is affected by:

condition of the cylinder-piston group - when worn, consumption increases by 20-25%,
coolant temperature – when it decreases relative to the optimum, the overconsumption increases by 8-10%,
high oil density, especially in winter, when friction in the engine and transmission increases losses,
clutch slipping,
a jammed brake caliper and an unadjusted brake system as a whole,
underinflated tires (a more economical option - slightly overinflated by 0.2 atm.),
over-tightened wheel hub bearings add another 10-15% to the consumed volume of fuel.

Next, we will look at what can affect and how to reduce fuel consumption on the VAZ-2106. Here we note that it will not be possible to reduce consumption below certain indicators, since the engine will not operate in air, but minimizing consumption as much as possible is quite possible. Here we will also not consider miracle devices and additives that supposedly can significantly help in this matter and reduce gasoline consumption by almost half. All this is nothing more than another way to lure money from the car owner, but there is no real benefit from it.

VAZ-2106 has high fuel consumption, then you can take some steps that can really have a positive effect on gasoline consumption.

Supply system

Let's go through the systems. Naturally, one of the biggest influences on consumption is the power supply system and its main element – the carburetor. If it is heavily clogged, and even incorrectly adjusted, then the fuel dosage is disrupted. Therefore, you should definitely check the condition of this element and wash it periodically.

The air filter also affects consumption. If it is heavily clogged, then its throughput drops significantly, resulting in a lack of air and an enriched fuel mixture enters the cylinders. Therefore, it is imperative to change the filter element on time.

Now about the adjustment work with the carburetor. Correct flow adjustment is important here. The fact is that by installing jets with a reduced cross-section and certain settings of quality and quantity screws, you can achieve a significant reduction in consumption. But at the same time, the power and dynamics of the car also drop.

This is where you need to adjust the carburetor so as to achieve the optimal middle ground between consumption and power. In this case, no jets need to be changed.

Ignition system

Now about the ignition system, since it also affects consumption. Heavily clogged spark plugs that have almost exhausted their service life and work intermittently, incorrectly installed ignition on the engine, losses due to breakdowns of high-voltage wires and tips - all this can have a significant impact on consumption.

Therefore, you should definitely check the condition of the spark plugs and replace them if necessary. The ignition must also be installed correctly. You can replace the standard distributor with a contactless one, which will reduce voltage losses and also facilitate maintenance and ignition adjustment.

All damaged wiring should be replaced (it’s not difficult to check it - just start the engine in the dark and open the hood. If any wires break through to ground, it will be very clearly visible).

The lubrication system also affects consumption, or more precisely, the lubricant. To reduce friction between engine components, you should use high-quality synthetic oil, which will further facilitate starting the engine in the winter season.

Transmission

Let's move on to the transmission. First of all, here you should check the condition of all component parts, repair and adjust if necessary. It is also necessary to promptly change technical fluids in the gearbox and rear axle to reduce friction and reduce the load on the engine.

If the VAZ-2106 is equipped with a 4-speed gearbox, then it can be replaced with a 5-speed one. In urban conditions, this will not give any savings, since 5th gear in the city, in fact, is not particularly needed. But on the highway, when 5th speed is used, the consumption decreases, and noticeably.

Chassis

Increased fuel consumption. Road and weather conditions

It happens quite often that increased fuel consumption is inevitable. Since it directly depends on road or weather conditions.

Example. If you are driving on a dry road without noticeable wind resistance, then naturally your car’s gas consumption will be within normal limits. In rain and strong winds, the fuel level can decrease much faster. There is no way around this, unless you don’t operate the car in such conditions.

Also, don’t discount the time of year. I think there is no need to explain that in winter the fuel gauge needle approaches zero much faster than in summer. The reason is not only poor road conditions, but also the daily warming up of the engine. We waste a lot of gasoline on this.

Setting up VAZ-2101 car systems to save fuel

The text of the article describes the development of options for machine systems to save fuel

When the financial and economic crisis is raging outside, almost every car owner thinks about how to save a couple of liters. expensive gasoline. Given that the owners of new cars are somewhat limited in their ability to reduce the fuel consumption of their own steel stallions, then the owners of old used cars can effectively configure a set of car accounting programs to meet the requirements for the lowest gas mileage.

Let’s create this using the example of the famous VAZ-2101, since it is one of the favorite “old ladies” on our roads.

What will still be useful, let's start with a set of accounting programs for ignition. For your information, its options play a very important role in the fuel consumption of the car. So, if the spark is untimely or, in other words, low-power, then the engine power is reduced. Fuel consumption of VAZ 2105, 21051 cars. Which, only after this, gasoline consumption increases.

To correct the situation, they begin by cleaning the breaker contacts without adjusting their gaps. An auto tester is perfect for such purposes. what is needed to install the injector on a VAZ How to wash a VAZ 2108-21099 on. As standard, the “penny” is equipped with a contact ignition system. How to adjust the steering column of a VAZ.

VAZ 2101-2107 REPAIR AND VAZ 2101 Coupe on the base. Here the breaker plate bearing often produces its own life. As a result, the contacts do not close and open in the wrong way, and the engine often “fails.” Therefore, in this version, the bearing and not the contact group changes. Then they move on to checking the spark plugs.

How to reduce consumption Fuel consumption is influenced by many factors VAZ-2101 1975 model year. Reasons for the increase in fuel consumption on the VAZ 2106 (1.3, 1.6, 1.5), adjustment and reduction of gasoline consumption on the Zhiguli 2106. It is necessary to clean them, then check the gaps between the electrodes. The latter can be set at 0.7 mm.

The ignition timing is set in accordance with the marks. Then they conduct tests on the move: on a flat road at a speed of about 50 km/h, they press the gas pedal sharply, “to the floor.” If the advance angle is correct, you should hear small and short knocking sounds. If the detonation is strong, the switch must be turned toward the “minus” side by one division, thereby making the ignition late.

To save money, you should switch to a calm style - with smooth presses on the gas pedal, approaching traffic lights in neutral, and performing maneuvers only when absolutely necessary.

You should also choose the right load on the engine, do not give increased speed, but run the engine a little “pull”.

It has been established that the speed of the VAZ-2106 power plant, at which the flow rate is most optimal, is in the range of 3000-5000 rpm. If you stick to this range as much as possible when driving, you will be able to reduce consumption, and significantly - up to 25%.

Music lovers will have to choose between music and gas mileage, especially for those who use significant audio equipment (subwoofer, large number of speakers). Heavy load on the on-board network affects consumption.

Therefore, to save money while traveling, you should reduce the use of electrical appliances to the maximum (use only the most necessary - headlights, light and sound alarms).

Excess weight in a car means grams of fuel. Therefore, it is worth taking out the unnecessary things from the car and leaving the really useful things - tools, spare tire, etc.

Windows open while driving become a wind tunnel. That is, the air flow enters the cabin at high speed, thereby resisting movement. And the more the windows are open, the stronger the effect of the oncoming flow. Naturally, in the summer it is impossible to drive in a completely closed car (especially since there is no air conditioning in the VAZ-2106), but still, to save money, it is worth using the interior ventilation system (open deflectors), which, in general, are not very useful in the heat, but If you open the windows, then not all and not completely.

All these recommendations will not work a miracle, but they will not only allow you to return gasoline consumption to the established standard values, but also reduce it slightly (in some cases it is possible to reduce consumption to 6 liters on the highway).

Finally, we note that consumption is affected not only by the technical condition and operating features. Savings also largely depend on the fuel itself. If it is of poor quality and contains impurities, then much more of it will be consumed (it will not be able to burn fully, hence the drop in power and the need to press the gas pedal more to obtain the necessary driving dynamics). Therefore, refueling with high-quality fuel, even if it is a little more expensive, ultimately results in savings.

The content of the article

Let’s assume that all Zhiguli owners agree that during that period of time we didn’t think about how to save fuel since it cost three kopecks, and everyone could afford at least a hundred liters a month. Only a few years ago, when global cataclysms hit our pockets, and fuel began to cost exorbitant amounts of money, we began to think about how to reduce the fuel consumption of a car, how to at least slightly reduce the appetite of our old VAZ.

We decided to install gas installations of unknown origin, because a high-quality branded one costs almost as much as our VAZ. At the same time, increasing the level of explosion hazard and reducing the engine life of the car, they also began to pour AI 92-93, 80 or, much worse, AI-76 instead of gasoline, deciding that since gasoline is cheaper, the savings in small bills remain in the pocket .

We can definitely say that this is not savings, but additional expenses that we are accustomed to not noticing, since this is hardware and it does not last forever.

Example: a VAZ 2101 engine lasts on average 220-250 thousand km. Between major renovations, think about where? Savings and how they happen. But that's not what this is about.

Average fuel consumption by car {amp}gt; at a speed of 100 - 120 km per hour, 8.5 - 9.7 liters per hundred kilometers, but this is not the limit, there is, and moreover, it exceeds 12 in the city, {amp}gt;.

In fact, your car's appetite can be reduced to 78l. There are a hundred ways, but as statistics say, not all of them are effective.

5mm, a combustion chamber and having delayed the ignition a couple of millimeters, they unanimously shout that now you can drive an AI76 and everything will be fine, is this saving? As a result, we have poor traction of the car with increased fuel consumption.

And the most important thing is that this is not an absurd misconception: a large number of car enthusiasts who believe that fuel consumption can be reduced by reducing the cross-section of the main fuel and air jets.

It can be said for sure that fuel consumption increases, this can be explained this way: the engine running on a lean mixture of fuel requires a larger opening of the throttle valve, also the lean mixture burns poorly and flies out through the muffler, as a result we have failures in engine operation when the throttle is opened, intermittent operation of the cylinders, engine detonation at idle, plus loss of power with a decrease in engine life, as well as an increase in vehicle toxicity due to (CH) and (NO). Car enthusiasts who don't believe it, check it out in your own cars.

As proof, carburetors produced for cars 2101 2103 until 1974 provided excellent engine dynamics, but were discontinued because they did not meet the requirements of existing toxicity standards.

Save fuel

First of all, good gas savings occur when the car’s chassis is well adjusted, the bearings are not overtightened and the car rolls slightly, the wheels are inflated to normal and the wheel alignment is adjusted, the ignition is set, the fuel system is adjusted and the valves are adjusted. Engine compression plays an even greater role; when the engine is worn to the limit, only repairs will help.

It should be added that there are special modifications of carburetors that save fuel consumption, while increasing some of the fuel metering elements, and improve the dynamics of the engine, but slightly increase toxicity. Example: carburetors.

Example: urban driving style, in a Zhiguli car there should be no jerking or sudden braking, the car should be accelerated smoothly, adhere to working standards, you should not press the gas in front of a traffic light to brake sharply, smoothly release the gas pedal and coast, do not make race. Remember: every press of the accelerator pedal is your money.

The most economical revolutions of the VAZ engine are from 3,000 to 5,000 per minute; these are the revolutions that provide the engine with the best dynamics, maximum power, increased motor life, and save fuel by 25/30%.
If you install a five-speed gearbox, the car will become a little slower to accelerate, and in urban driving you won’t be able to save money; you’ll save fuel only on the highway.
{amp}gt; so even at 6 liters per hundred, you can meet it)).

The aerodynamics of your car, and everything that interferes with it, wide tires not provided by the factory, decorative spoilers, muzzles, so-called fly swatters, top trunk. You can also remember: power supply, it costs money, do not turn on the lights unless necessary, this is a load on the engine, of course, except in those areas where you are supposed to drive with it.

Vehicle load and operation with a trailer

There was no need to write about this at all. Since it should be clear to everyone that the greater the load on the car, the more power the engine will have to spend. And accordingly, much more fuel will be consumed. This is especially noticeable when operating with a trailer, so you should pay attention to this too!

Of course, there are still many factors that can negatively affect the increased fuel consumption of the VAZ 2106. And if you want to add to this list, then you can easily share your opinion in the comments below!
