Fuel Pump Metering And Distributing Camshaft

The fuel pump metering and distributing camshaft is a component of a fuel injection system in an internal combustion engine. It is responsible for controlling the amount of fuel that is delivered to each individual cylinder.

The camshaft is a rotating shaft with specially shaped lobes or cams that open and close the intake and exhaust valves of the engine. In the case of a fuel pump metering and distributing camshaft, it also controls the operation of the fuel pump.

The fuel pump metering and distributing camshaft is typically driven by the engine's crankshaft through a timing belt or chain. As the camshaft rotates, the lobes or cams push on the fuel pump plunger or diaphragm, which in turn pressurizes the fuel and delivers it to the fuel injectors.

The shape and timing of the lobes on the camshaft determine the amount of fuel that is delivered to each cylinder. This is crucial for maintaining the proper air-fuel mixture and combustion process in the engine.

Overall, the fuel pump metering and distributing camshaft plays a vital role in the fuel injection system, ensuring that the engine receives the correct amount of fuel for optimal performance and efficiency.
