![]() ![]() The main function of this valve is to control the quantity of the air inside the mixing chamber. ![]() Choke valve:Ĭhoke Valve is a valve that controls the mixture of air-fuel. In addition to the main nozzle in the venturi portion of the carburetor, two other nozzles, or ports, deliver fuel to the engine cylinder. And then supplied to the engine cylinder. In the mixing chamber, the mixture of air + fuel occurred. When the level of fuel decreases in the float chamber the float moves downward, which opens the fuel supply valve and allows the flow of fuel into the float chamber.Īs the fuel level increases, the float moves upward which close and stop the fuel supply. It contains a float valve that maintains the level of fuel in the float chamber. The float chamber serves as a storage tank of fuel for a continuous supply of fuel. It works during idling or when the throttle is open below 15%. ![]() It provides a rich mixture during idling and at low speed. The idling system consists of passage directly from the float chamber to the venturi tube. The quantity of fuel is control by the metering orifice and discharge hole at the exit of the fuel discharge nozzle. Due to this pressure difference, fuel is discharged into the air stream. When the air passes through venturi, it generates a low-pressure field across the throat. It is responsible to form a correct mixture of air-fuel. The metering system controls the flow of fuel into the nozzle. For which fuel comes out from the fuel pipe. It helps to decrease the air pressure of the chamber. The venturi is the gradually decreasing cross-sectional hollow tube. If these particles not removed, it can cause blockage of the nozzle. It consists of a fine wire mesh which filters the fuel and removes dust and other suspended particles from it. It is a device that is used to filter the fuel before entering the float chamber. Carburator diagrams driver#The driver opens the throttle valve by pressing the accelerator. Throttle Valve is an important part of a Carburetor. It controls the mixture of charge (air+fuel) supplied to the engine cylinder. Automatic mixture control Throttle Valve:.So what are the parts of a Carburetor? A simple carburetor is constructed of the following parts:Īnd also a modern carburetor consist of additional these parts: ![]()
