fuel injection pump

The fuel injection pump is a key component in the injection system of gasoline and diesel engines. Its function is to pump the fuel under high pressure and deliver it precisely to the injectors or the common rail system.

In modern injection systems, the fuel is supplied by the injection pump at a precisely defined pressure so that the injectors can finely atomize the fuel and inject it accurately into the combustion chamber. This process is crucial for efficient combustion, optimal engine performance, and reduced emissions.

In diesel engines, the high-pressure injection pump often generates pressures of several hundred to over a thousand bar. The pump operates in close coordination with the engine control unit, which regulates the fuel quantity and injection timing depending on engine speed, load, and temperature.

Fuel injection pumps consist of precision-manufactured mechanical components such as pistons, valves, seals, and high-pressure elements. These components are designed for extremely high pressure loads, continuous operation, and contact with fuel.

A properly functioning injection pump is crucial for smooth engine operation, efficient combustion and a reliable fuel supply.
