Device carburetor VAZ 2107. How to adjust the carburetor VAZ 2107 independently

Every motorist sooner or later starts to think about how the car is arranged, simple driving becomes uninteresting. Beginners strive to independently repair the various parts of their cars. VAZ-2107 is the ideal first car. Many are interested in carburettor adjustment on these machines. Consider the device carburetor VAZ-2107 and ways to adjust it.

How is the carburettor

Several types of these devices were installed on the VAZ-2107. This is DAAZ-2107 produced by Ozon and Solex. Before the model was removed from production, it was completed with Ozone products. Consider the device carburetor VAZ-2107 DAAZ.

The element consists of a float chamber and a float. Also the device is equipped with a needle valve, filters, mixing chamber, throttle and throttle. There is an air damper, an ekostat and jets, an accelerator pump and diffusers. Each element plays a special role in the preparation of the optimal fuel mixture for the power unit.

Principle of operation

To better understand the carburetor device VAZ-2107, you should study how this mechanism works. Also, this knowledge will help in self-adjustment of the device. This is very useful information. So, the fuel gets into the float chamber, where the level of fuel is regulated with the help of the float. When the part emerges, this results in the actuation of the needle valve. The latter blocks access to gasoline.

Before entering the chamber, the fuel is cleaned through the filter. Then the gasoline is divided between the first and second chamber. It passes through fuel jets. A combustible mixture is not only gasoline, but also oxygen. So, clean air that passed through the air filter passes through the jets. The carburetor device VAZ-2107 also includes special emulsion wells and tubes. In them, gasoline is mixed with air, resulting in a mixture that can easily ignite.

Further, this emulsion enters the econostat, and then into the spraying device, along the way is further enriched. Then the fuel mixture enters the diffusers, where the final product for the combustion chamber is created. With the flow of air, the mixture will fall directly into the center of the mixing chamber. In the engine, the fuel mixed with air gets through the throttle, and the throttle is controlled by the accelerator pedal. Jets, with which the engine can run at idle, allow you to get a fuel mixture only from the first chamber. When the car is running at full power, petrol is also taken from the second chamber. Completely it is used only when overtaking or a sharp need to gain speed.

In order for the engine to function properly, the carburetor must be in perfect condition. Keep the jets clean. Also, all working surfaces must be clean. The carburetor device VAZ-2107 DAAZ is quite simple, and he is unpretentious, unlike imported models. It functions perfectly even on inexpensive domestic gasoline, which does not have a special quality.

Carburetor Solex

You can very long argue about what is better - "Solex" or "Ozone." But these disputes lead nowhere. Consider a device for modifying the carburetor "Solex" for the "seven". The carburetor device VAZ-21073 "Solex" is also quite complicated. In general, the unit consists of a body and a cover. In the first there are two mixing chambers equipped with diffusers. There is also a float chamber, emulsion wells and jets for fuel and air. The device includes an accelerator pump, an economizer, an economizer, screws for adjustments, a throttle valve and a starting device for the carburetor VAZ-2107.

Now go to the lid. In it there are fittings for fuel, as well as studs for fixing the air filter. It also has a solenoid valve and the necks of the two mixing chambers. The lid is provided with channels for air supply to the air jets. There is a needle valve and some other elements.

How to adjust the carburetor VAZ-2107 independently?

This issue is very important for most car owners. Specialists in carburetors are now very few, and such cars are still traveling around our country. And in order not to waste time searching for a good specialist, many people try to learn how to set up themselves. If you know the carburetor device VAZ-2107, the adjustment process will be more understandable for you. To configure, you do not need special knowledge.

Carburettors can be of different manufacturers and modifications - adjustments for almost all models do not differ. The principle here is one. But it is not superfluous in this process to at least at a general level know the device of the engine VAZ-2107. The carburetor will be much easier to adjust.

Setting the float

To start the adjustment, first of all it is recommended to remove the air filter. Then unscrew the lid of the device and look at the fuel level. The maximum fuel level will be in the chamber where there is a needle valve. Next, check the float. It should only touch the valve lightly. To adjust the float you will need a special template. It can be made of paper. Its dimensions should be 6.5x14 mm. This template is set from below under the float. Normal for this carburetor size from the gasket to the float should be about 6.5 mm.

If this size does not match the normal, the float tab adjusts. By removing the float from the lid or into another string, it is possible to adjust the opening of the needle valve. The template installed at the bottom of the float must match the size. By manipulating the support on the bracket to which the float is attached, set the required size, if it differs from the factory one.

Starting device

The starting device of the carburetor VAZ-2107 can be checked using a piece of wire. The length of the segment should not be more than 20 cm. The cross section is approximately 0.7-0.8 mm. Then prepare a template from the cardboard. Its thickness should be 1 mm, and width - 5 mm.

Then the cover is wrapped in place. The starter has a stem. It should be immersed to the stop, and then using a template to measure the distance from the wall of the cylinder to the edge of the air damper. In an ideal situation, this size should be within 5-5.5 mm.

Adjusting the air choke opening clearance

To do this, using a screwdriver, you can remove the protective plug, which is installed on the adjusting screw. With it, you can adjust the necessary clearance.

Throttle Body

To do this, remove the carburettor completely. Then, clockwise, it is necessary to turn the lever firmly to the stop.

With the help of a wire, the clearance is checked, which should be within 0.7-0.8 mm. If the size does not match, then it can be adjusted by bending the rod or by fitting it into another hole.

Air damper actuator

To perform this adjustment, the carburetor must be screwed to its rightful place, but the air filter should not be installed. Further one hand holding the lever, controlling the throttle, move it to his side. The part will be set to its normal position. If there are any inconsistencies, then you need to hold the flap with one hand, and then use a wrench to unscrew the screw holding the pull rod. As a result of these actions, the mechanism will arise correctly. It remains only to tighten the screw.

After this procedure, the setup process can be considered finished. You can install the device in the right place, twist the air filter, connect the hoses and wires. Then you can start the engine. So the independent adjustment of carburetor VAZ-2107 is carried out.
