Electric carburetor for carburetor: characteristics, installation

The carburettor is one of the components of the engine power system. It is designed for the preparation of an optimal fuel and air mixture. In the carburetor, gasoline is mixed with air. Also, this element regulates the volume of supply of the mixture to the combustion chambers. Carburetors are still quite popular and are used not only on the classic models of AvtoVAZ, but also on some foreign cars.

Characteristic

Invented the carburetor long enough. Massive these devices were produced in the 20th century. However, technological progress does not stand still, and in exchange the carburetor was supplied with an injector power system. The carburettor is an old enough mechanism. Its work is often supported by mechanical devices. The action of the injector system is electronically controlled. Many owners of carburettor cars come to combine mechanical carburetor with modern devices. One example of such a synthesis is the installed electric fuel pump to the carburetor.

Petrol pump: main types

This device, as is clear from the title, is designed to supply liquid gasoline from the tank straight to the combustion chambers of the engine. The main task of any pump is to pump the fluid under the required pressure level, which is necessary for the motor to work as stable as possible. Modern technologies slowly, but confidently capture the world. Innovations also come to the automotive industry, but mechanical pumps are still used on carburetor motors. The mechanical device was created exclusively for working with the carburetor. But the electric gasoline pump is designed for injection engines. The mechanical element is installed most often outside the tank, but the electric one can be found inside it. It is submersible. Electrobenzonasos for carburetor - this is not the fruit of modern technology. This is the find of the motorists themselves. The fact is that the electric pump increases the efficiency of the carburettor and the engine as a whole.

Operation of an electrical element with a carburetor

The electric fuel pump is very similar in principle to the mechanical device. The main task of the element is to ensure the supply of gasoline from the tank and then to supply it to the cylinders. I must say that with carburettors, electric pumps operate at low pressure, unlike the injector. There must be a higher pressure in the fuel system. In addition to the injector engines, an electric gasoline pump is installed directly inside the gas tank. In the case of a carburetor, it will be located next to it under the hood. Therefore, the system operates at lower pressures. But for such an installation it is necessary to have specialized equipment, which can only be done at the service station. And if the car owner wants to install an electric fuel pump with his own hands, then it is better to introduce the device into the tank.

Construction of the electric blower pump

This device according to the device and the principle of operation is very similar to a mechanical device. The work is carried out thanks to the core. It is retracted by a solenoid valve. The low-pressure electropensor pump consists of a working chamber, valves - inlet and outlet, diaphragm, return spring, electromagnetic sensor, core and contact group.

The algorithm of action

The device works due to the movements of the diaphragm. It moves up and down. As a result, a depression occurs on the diaphragm as it moves downward and the inlet valve opens. Through it, fuel enters the cavity in the diaphragm, after passing through the filter. When it moves upwards, a certain pressure is created, and the intake valve closes. Then the outlet opens, and the fuel moves further along the fuel system. Now carburetor engine power systems have been massively equipped with electric pumps. This is easily explained by the mass of advantages that are not in the mechanical device.

Tuning the carburetor: installing an electric fuel pump

Do not think that for all the simplicity of the element, mounting it into another power system will be simple. Installation of the electric blower pump is a rather complicated process. But the result is worth the effort. First of all, it is necessary to determine which particular pump is suitable for the carburettor and the power supply system. Also, various consumables will be needed for installation.

Necessary materials

In order to install an electric pump, you will need a hose. Its length should be at least 5 meters, and the inner diameter - about 8-9 mm. Also, a remote low-pressure gasoline pump and a relay to it are purchased. From tools it is necessary to find a drill with a diameter of 3-4 mm. Additionally, a filter is purchased from the engine's injector system, as well as a carburetor filter. Still need a tube of steel with a wall thickness of 0.8 millimeters and a diameter of 7 millimeters. The length of the pipe must be at least 250 mm. Also, a 12 mm hose and a plug connection for the plug from 8 to 12 mm are required.

Installation work

First, remove the fuel level sensor - it is in the tank. A hole is drilled in the lid and a 7 mm tube is soldered to the soldering iron. The end of this tube must be bent - this is to ensure that the return line is draining. The bend should be such that one end of the tube is at a greater distance than the fuel sampling pipe. The upper part also bends to parallel with the fuel intake opening. Next, a modern fuel level sensor is mounted. It should be noted that it has both a fence and a return line. It is installed in the tank. It is important to know: the rubber tube must be connected by a "return" connection from the fuel system. Then the end of the prepared hose is connected to the fuel inlet. Then the elements are fixed to the metal pipe with the help of clamps. The low-pressure electric pump itself is installed horizontally to the motor board through a special bracket through rubber cushions. They are included with the device. It is very important to set the device to the correct position, at which the suction will occur from the side of the expansion tank, and the flow head is directed towards the motor. Then a filter from the injector is attached to the fuel supply hose.

On the second fitting put a tube with a diameter of 5 mm. It is fixed with clamps on the body in an upright position. It is necessary that the combustible mixture is fed correctly, that is, from the bottom up. The pump is connected to the tank using a 12 mm hose and an adapter. Then it is worth to do high pressure. In the carburetor it is not necessary. To lower it, remove the lid from the pump, unscrew the feed pipe and take out the mesh. In the return pipe connection, drill a hole up to 3 mm. Then it remains only to connect the electric fuel pump to the carburetor using an ordinary fuel filter. It's easy to do. Only clamps and a hose are necessary. Connect the device to the 12-volt contact on the ignition coil via a relay.

Pros of an electric gasoline pump with a carburetor

There are many reasons why an electric petrol pump is installed on the carburetor. One of the major advantages is how the engine starts. Now the motor will start quickly, almost instantly. The pump starts immediately, as soon as the driver turns the key in the ignition switch. Significantly reduced noise activity. The electric pump is practically noisy. In the salon will no longer smell like gasoline, as before. And, finally, the main plus - the ability to reduce fuel consumption by a small percentage.

Conclusion

As you can see, this is a useful refinement. Having installed an electric petrol pump on the carburetor of VAZ or any other cars, you will not encounter any shortcomings. The only difficulty is choosing the right device and installing.
