What is a Carburetor and how does it work? This information will explain the working principle of the carburator and the functions of each part of the carburator .
By creating low pressure in the cylinder, the piston’s intake stroke creates atmospheric air. The stroke volume and average velocity of the piston determine the flow rate of air into a cylinder. This is how Otto engines mix fuel and air.
By narrowing the cross section of the air that has been pumped into the cylindrical via the suction channel, flow rate increases and pressure decreases in this area.
In the following figure, you can see the basic operating logic of a carburetor system. Accordingly, the fuel is sprayed using the fuel system. The open end is exposed to air. The pressure is then reduced by the main nozzle.
Low pressure in the venturi bottleneck, and variation in fuel level in fixed cup can affect the amount of fuel that is injected into the venturi. Under certain operating conditions, the fuel level of the constant-level container is maintained at a specific level. This prevents fuel from changing in the venturi. This is done by closing the fuel intake of the float. The fuel level in the container increases with increased fuel. If the fuel level drops in the fixed-level container, the fuel inlet of float will open and allow the fuel level to reach the desired level.
In a simple carburetor, the main nozzle measures the fuel being sent to the venturi in order to get the right mixture of intake air and fuel. Load adjustment can be done in otto engines using the carburation method. This involves changing the amount of fuel entering the cylinder. A throttle valve is placed in the suction channel connecting the venturi to the cylinder. This allows for the adjustment of the filling volume.
Carburetors have this basic working logic, but there are other types.
