Functionality fuel pump
The electric fuel pump delivers the fuel at a defined pressure to the injection valves. These inject the fuel into the intake manifold (intake manifold injection) or directly into the combustion chamber (gasoline direct injection). In intake manifold injection, the electric fuel pump delivers the fuel from the tank to the injection valves. With gasoline direct injection, the fuel is also pumped from the tank by an electric fuel pump. It is then compressed by a high-pressure pump through higher pressure and fed to the high-pressure injection valves. Regardless of whether the engine is cold or has already warmed up, the electric fuel pump (EKP) has an important task. It supplies the engine with sufficient fuel at the pressure required for injection.
