The most popular carburetor model oncars VAZ-21083 - "Solex". Most cars of the 8th and 9th families were produced with engines having a carburetor injection system. At the beginning of the 2000s injector injection was first introduced. Carburetors of this model are very easy to adjust, there is almost no fine tuning, the design does not include complex knots and mechanisms. In the article we will consider all the details that the carburetor "Solex 21083" has.
Carburettors DAAZ-2108 began to usecars VAZ in the mid-eighties. The very first machine to which they were installed was the VAZ-2108 model. They worked with motors of 1.1 and 1.3 liters. After the launch in the production of cars with engines of 1.5 liters there were carburettors "Solex 21083". The digital designation indicates that the device is mounted on VAZ-21083 engines, the volume of which is one and a half liters.
The main purpose of the carburetor is the preparation of a combustible mixture of gasoline and air, which ensures normal operation of the engine, regardless of the loads and the number of revolutions.
Structurally the carburettor is made of several elements:
The carburetor is a two-chamber device, inthe main metering system is located jets. They are installed in the cells in the middle, inside the case. In the upper part, the air jet nozzles of the dosing system were installed. The design provides for a small unit, which heats the fuel mixture. To it are connected the hoses coming from the nozzles of the cooling system. In the lower part of the body there are two throttle valves, which alternately open. The opening of the dampers takes place in series, with the help of levers. On the lid there are two branch pipes, which are designed to supply gasoline and drain excess oil back into the tank.
On sale there are kits for repair.They consist of air and fuel nozzles of the secondary and primary chambers. There are several types of repair kits that can work with different engines. It all depends on the cross section of the diffusers. In some cases it will be much better to buy a carburetor VAZ. The price of the new is about 4000 rubles.
Since this type of carburetor caninstalled on the engines of other cars, then using standard jet nozzles their cross-section is not enough. At the engine, the requirement for a fuel-air mixture is one, and the carburetor makes it absolutely with a different proportion. To improve the acceleration and dynamics, you can install a jet with a large cross section.
But at the same time the consumption of gasoline is much increased.Also it is necessary to know that the installation of such jets does not guarantee a 100% positive result. You will do the right thing, if you do not experiment, but simply install the kit on the carburettor designed for this engine.
If the carburetor is installed on the engineVAZ-21083, it is better to use jets, designed specifically for him. If, even when installing jets with a large diameter, the acceleration of the machine is weak, there can be several reasons:
There are many reasons why the engine does not develop the necessary power. To identify them, you will need to conduct a thorough inspection of the vehicle and the diagnosis of all components.
The feasibility of installing the carburetor "Solex21083 "for other models of cars is very doubtful, as the savings are small. And then only when the driver drives carefully and does not accelerate sharply. For this reason, it is best to install the carburetor on the engine with which it will work as perfectly as possible. It is also necessary to choose from the factory proposed.On the carburetor "Solex 21083" adjustment is easy to carry out, but to achieve the ideal work on engines with a large volume is problematic.
Before buying, pay attention tomanufacturer repair kit. Very often come across Chinese cheap products that do not differ in quality. The diameter of the jets section may differ from the declared value, therefore, the carburetor will work incorrectly. Buy for the carburetor "Solex 21083" jets that are included in the repair kits, only from a trusted manufacturer who has established himself from the good side.
Only three adjustments can be made on the carburetors "Solex 21083":
The last adjustment is quite simple.It can be done by anyone. To do this, the engine warms up to operating temperature, and with the help of a screw of the mixture amount, the crankshaft rotation speed is set at 800 rpm. Further actions are:
Otherwise, it is necessary to stabilize the motor operation with a screw.
At the carburetor "Solex 21083", adjustmentwhich is discussed in the article, sometimes there is one problem. This is the inability to correct idle speed with the help of a mixture quality screw. The reasons for this behavior:
To verify the performance of the electric valve, you must perform a number of actions:
If there was a click, and the valve stem sank,freeing the holes in the jet, then there are no problems with the device. Otherwise, you need to install a new solenoid valve. Very often small specks fall, therefore it is necessary to blow the jet. The operation of the solenoid solenoid valve can be checked if the wire is removed from the handpiece with the engine running. The engine should almost instantly stall, it means that the mechanism is working.
In order for the fuel supply and consumption to be balanced by the fuel system, the level of the float must be set. For this:
When you are setting up, you need to consider thatthe floats must be level. All work is done relatively simply, change the jets to "Solex 21083" and make adjustments - this is the maintenance of the injection system.
