K151S carburetor, developed and manufactured at the Pekar plant (former Leningrad carburetor plant). This model is one of the modifications of the 151 line of.

Chainsaw is one of the irreplaceabletools in a private household. It is very important that this tool functions continuously and without interruption. The quality of the chainsaw's operation largely depends on the reliability of the carburetor. As it is used Walbro.

This carburetor is quite reliable. But he sometimes needs adjustment, prevention and repair. Well, let's look at the features of this node. Mechanism arrangement The device is supplied in an aluminum casing,which is made by casting. Inside it there are internal channels with contours. These are diffusers. Air passes through them, which is then sucked up by the internal combustion engine.

The diffuser has fuel channels.When air passes through the element, it is connected to the gasoline stream, forming a combustible mixture. The fuel pump, the system of jets, as well as the mechanism that allows you to adjust the parameters of the mixture, are installed from the outside and are integrated into the Walbro carburetor. The power that can be developed by the engine chainsaw, as well as the amount of air in the carburetor, is regulated by the throttle. Pump impulse chamber for fuel injection.

It is delivered via a pulse channel, which connects to the motor boat. Regal resonator guitar serial number. When the piston in the cylinder moves, the pressure in the crankcase changes.

These changes affect the operation of the fuel pump membrane. The pump is forced to start, while its operation is synchronized with changes in pressure in the crankcase. Its level depends on the engine speed.

The fuel is fed to the carburetor from the tank through a special carburettor fitting. Passes through a diaphragm, an inlet and an exhaust valve on the fuel pump, and also through the filter. Then the mixture along the fuel channel past the needle enters the chamber where the control membrane is located. Needle valve, or rather a needle, with the aid of a lever is in connection with the membrane. The chamber below it, through a special hole, opens into the atmosphere.

Operating principle Carburetor Walbro for chainsaw functions forthe pressure change in the crankcase of the motor. At the beginning of the intake stroke, the air begins to flow through the diffuser by means of a vacuum. Its volume depends on the speed of the motor and its load. Also, it depends on what positionis the throttle. I doser v45 128 doses download free. It is controlled by a special handle.

Using fuel jets, during the passage of air, a mixture is formed. Next, gasoline is sprayed and a finished mixture is obtained, optimal for combustion. Usually, it is prepared in a proportion of 1 to 14. Then the mixture will fall into the cylinders, where the combustion cycle takes place. Due to the fact that the volume below the control membrane is connected to the atmosphere, it is shifted upwards.
