Metering And Distributing Fuel Pump

A metering and distributing fuel pump is a device used in fuel injection systems to accurately measure and distribute fuel to the engine. It is responsible for delivering the correct amount of fuel to each individual cylinder at the right time, ensuring optimal combustion and engine performance.

The metering function of the fuel pump involves measuring the precise amount of fuel that needs to be injected into the engine. This is typically done by using a sensor or a mechanical mechanism that calculates the engine's fuel requirements based on factors such as engine speed, load, and temperature.

Once the fuel amount is determined, the distributing function of the fuel pump comes into play. It distributes the fuel to each cylinder through individual fuel injectors. The fuel injectors are controlled by the engine's electronic control unit (ECU), which receives input from various sensors to determine the optimal timing and duration of fuel injection.

Metering and distributing fuel pumps are commonly found in modern fuel injection systems, such as direct injection and common rail systems. These systems offer better fuel efficiency, improved power output, and reduced emissions compared to traditional carbureted systems.

Overall, the metering and distributing fuel pump plays a crucial role in ensuring the proper delivery of fuel to the engine, resulting in efficient and reliable operation.
