Adjustment and adjustment of the carburetor VAZ-2109. How to properly adjust the carburetor VAZ-2109

There are a whole lot of reasons, because of which you may need to adjust the carburetor VAZ-2109. This and low-quality fuel, contaminants in the form of waste lubricants, debris from the environment. But in the process of constant use this mechanism does not require special care outside. If there is a strong contamination of rubbing and moving parts, it is time to perform cleaning and adjustment.

How to understand that the carburetor is not tuned?

It's pretty simple. In principle, an experienced motorist immediately understand what's what. But if you are just a beginner, you should know that there are a number of signs and that you do not need to repair the carburetor VAZ-2109, you need to be able to understand them. First, the car stalls while riding. This can happen if you go on a cold engine without a suction, which is quite normal. But when the engine got the working temperature, you let go of the gas, and the car withers, it means that it's time to clean it.

Secondly, if the crankshaft revolutions are typed with difficulty, then this indicates a poor draft - and again the carburetor is guilty. When the car rides on a flat road at idle speed and jerks, then this is a clear symptom of the malfunction, which is recommended as soon as possible to eliminate.

In principle, there are still a lot of signs, which determine the malfunction of this unit of the car. Moreover, a competent adjustment of the carburetor VAZ-2109 will help to avoid increased fuel consumption, which is especially true if we take into account today's gasoline prices.

Screws of "quality" and "quantity"

It is recommended to do the work together, because it is inconvenient to constantly run from the carburetor to the accelerator pedal, get and throttle the throttle. But this is an optional requirement. What you need to know is that the adjustment can be performed without the presence of any special tools and other devices. In simple words - with your bare hands.

But for this you need to know what screws of "quality" and "quantity" are. The first serve to ensure that you can get an unstable motor work. Rotating in the reverse order gives normal operation of the engine. In this case, the "quantity" screws serve to increase or decrease the speed. After that, they go back to adjusting "quality", then "quantity", etc. In practice, all this is quite simple. Nevertheless, in a car repair shop for such a simple adjustment will take a decent amount.

Preparatory work

Before you configure the carburetor VAZ-2109, you need to meet a number of requirements. Of course, this is not necessary, but it is desirable. First of all, work should be carried out in a well ventilated area. It is desirable, that the car stood strictly horizontally or under an inclination no more than several degrees on any axis.

During internal cleaning, you should not use rags, as the villi will remain inside, which will contribute to improper operation of the nozzles. In other words, the adjustment will be brought to nothing. Cleaning and adjustment of the carburetor VAZ-2109 should be made by special preparations. If such a tool is not at hand, then suitable gasoline. The best results can be obtained with the use of compressed air. So, we have prepared for the execution of the work, now we can proceed to the practical part.

Adjustment of the carburetor VAZ-2109: general provisions

Directly before adjusting, clean it. You can use gasoline, compressed air or special. facilities. During work, you need to have a flat screwdriver at hand. Also, ignition is regulated before adjustment and cleaning. It makes no sense to adjust the carburetor, if it is installed later or early ignition.

Another thing to remember is that the adjustment is carried out only at the engine operating temperature, that is , it is desirable to warm up the car and only then proceed to the process. With the throttle, you need to remove the draft from the gas pedal. Immediately after this it is necessary to disconnect the crankcase ventilation. Next, we perform a check for the absence of a vacuum in the advance control tube. If it is, then something is done incorrectly. Then you can proceed to adjust the quality screws that will allow you to adjust the stable operation of the car's motor.

Adjust the throttle

This "suction", which is necessary when the engine is cold starting. There are several reasons for this mechanism to fail. Despite the fact that its device is simple, it is advisable to pay close attention to its repair. The throttle is a kind of lifesaver at sub-zero temperatures. Therefore, the adjustment of the carburetor VAZ-2109 must begin with a "suction".

First of all, check the cable tension. Here you can face the following problems: insufficient or excessive tension. As both, the one and the other contributes to the fact that the damper does not open or close completely, which is not good for the carburetor.

To perform the work, we need a key to 13, which we will adjust the tension of the cable. If the gas pedal is squeezed into the floor, then the flap must fully open, letting go of the gas - the flap is closed. If this is not the case, then adjust the position of the locknut when using the key to 13, until we reach the optimal results.

Air damper drive and its adjustment

After we have adjusted the throttle actuator of the carburettor, go to the air damper. First of all, before removing the cover, remove the cover from the air filter. By the way, in passing you can change the filter, especially if it was done for a long time. The stroke in the shell must be free.

If the damper does not require adjustment, then with a fully recessed handle the suction is under the torpedo. The damper should be open by 100%. If this is not the case, then it is necessary to loosen the thrust bolt with a wrench. Let's move on to setting up. Once the optimum result is achieved, tighten the bolt to the lever and close the filter cover. But here there are nuances.

The first thing to do is to turn the damper lever until it fully opens. After this, you must dump this lever as far as it will go. Using pliers, take the cable out of the insulation and press the bolt. We check whether the flap opens completely. If necessary, gradually move the cable sheath and tighten the fastening bolt.

How to adjust the carburetor VAZ-2109: starting device

A lot depends on the work of this mechanism. But in order to make the adjustment as precisely as possible, it is necessary to dismantle the carburetor. It is not difficult to do this. But if it does not, then you can try to perform the setting on the installed mechanism. The principle is that it is required to correctly set the starting gaps. This will determine how well the machine will start.

As noted above, there are several ways how to adjust the carburetor VAZ-2109. If without removing, then a tachometer is required. First, it is necessary to completely remove the air filter housing, then completely pull out the air damper lever (located under the torpedo in the passenger compartment). We start the engine and observe.

Using a flat screwdriver, open the air damper by about 30%. We take the key to 7 and rotate the adjustment bolt until the result of 3100-3400 turns is visible on the tachometer. As soon as this figure is obtained, you can safely omit the flap.

What you need to remember during the repair work

Everyone knows that the engine is the heart of the car, while the carburetor is its valve. If the second fails, all systems suffer completely. Therefore, in order to have the state of the vehicle at the level, it is necessary to periodically repair the carburetor VAZ-2109. But as for the repair itself, it is better to entrust it to professionals, since without experience one can only aggravate the situation.

It is also desirable to refuel high-quality fuel, because it affects the performance of the car and the carburetor itself. Lubrication is another important point. Without it, nothing will work, so the same "quality" screws should be greased from time to time. The same applies to the air damper cables, which must periodically change. As practice shows, they fail at the most inopportune moment.

Adjust the idling speed of the carburetor

So, first of all, warm up the engine to operating temperature. The work needs to be done with the power-up elements (lights, player, etc.) turned on, so it is advisable to charge the battery before starting work so that it does not sit down at the wrong time. Work is necessary, again, with the screws of "quality", but the sequence is slightly different.

First you need to get the maximum speed at idle (x.x.). After that, rotate the "quantity" screw until the speed is about 50-150 less than it should be on x. X. As a rule, this is about 800 revolutions of the crankshaft. After that, the screw of "quality" reduces the value to normal - approximately 900-950 revolutions. After this work can be considered fulfilled. It is worth remembering that the replacement of the carburetor VAZ-2109 may be necessary only if you do not pay attention to its malfunction. As a rule, this mechanism can work for a long time. But do not forget about cleaning and customization.

About Solex carburettors

A couple of words need to be said about setting up this device. The first stage is the installation of the correct level in the float chambers. After this, perform idle speed adjustment. It is worth noting that the tuning of the carburetor "Solex" VAZ-2109 should be carried out according to the instructions, which will not only accelerate, but also simplify the work.

If the engine does not react when adjusting the "quantity" screw, it is necessary to change the idler to a smaller one or to tighten the solenoid valve. As for the selection of jetlocks, this is a rather laborious process. It is necessary to be guided by the working volume of the engine. The more volume, the less need a jet.

There is also a transitional regime, which is responsible for the absence of a failure during the start of the car and its normal operation (sneezing, shots). The whole fault is a slotted hole. It is located directly under the throttle valve. If you press the accelerator pedal, then the gasoline from the jet nozzle is fed into the hole. If this does not happen, the car may die out.

Theoretical information

It would be superfluous to say that the carburetor is a device whose direct purpose is the mixing and dosage of fuel coming into the cylinders of the engine. Otherwise, it is here that the working mixture is formed. The quality is the responsibility of the jets. This applies to all models of the domestic car industry, including the VAZ-2109. The carburetor is crumbling due to incorrectly tuned jet nozzles.

In addition, such an indicator as their productivity is important. It is obtained from the length of the nozzle, as well as its opening (throughput). If you increase the cross section of the nozzle by about 10%, then the throughput increases by 25%. From this it can be concluded that when correctly configured devices described can not only reduce fuel consumption, but also increase engine power. As we see, tuning the carburetor VAZ-2109 allows a lot.

Because of what are the problems

As a rule, the carburettor itself will work normally with proper care. However, there are several nuances that you need to pay attention to. For example, after the installation of the carburetor VAZ-2109, there was instability in the engine on x. X. The reason for this may be the wrong tension of the accelerator cable (accelerator). But all this is easily corrected, and now we'll see how.

To begin with, you need to conduct an accurate diagnosis. Therefore, it is necessary to disconnect the accelerator wire from the carburetor. This is done so that you can manually adjust the throttle on the running engine. If, during the movement of the throttle, the revolutions fall to the required speed, then it is necessary to change or adjust the cable. If the turns have not changed, then it's still in the carburetor.

Conclusion

I would like to say that a simple adjustment of the VAZ-2109 ignition is often required. The carburetor in this case can work normally, but because of unconfigured ignition there is a feeling of its malfunction. As it was repeatedly said above, much depends on the quality of the carburetor mixture.

It is not recommended to replace the nozzles by yourself. This is due to the fact that each of them is suitable only for a certain carburetor model. If you install from any other, the fuel consumption can increase, the engine power - decrease, the dynamics become worse, etc. But if you still need to perform a replacement, you should be guided by the marked markings. You need to buy the kit immediately, and not separately, as it is unsafe and you can run into a discrepancy with the marking.
