High pressure fuel pump plays a crucial role in the engine fuel system. The main functions of the pump are as follows:

1. Fuel supply: The high pressure fuel pump draws fuel from the fuel tank and delivers it to the combustion chamber of the engine. It creates sufficient pressure to push fuel into the fuel injector or injection device and complete fuel injection and combustion cycles.

2. Pressure regulation: The high pressure fuel pump constantly maintains the pressure in the engine fuel system in an appropriate range by controlling the supply and pressure of fuel. This helps ensure stability and accuracy of fuel injection and best combustion effect.

3. Fuel injection: The high pressure fuel pump injects fuel at high pressure into the engine's combustion chamber. This is necessary for normal operation of the engine, as it ensures that the fuel can be fully burned to provide required power and driving force.

4. Fuel system protection: The high pressure fuel pump also serves the critical role of protecting the fuel system. It is able to filter out impurities and particles in the fuel, thus preventing them from entering the engine and causing damage. Besides, the high pressure fuel pump can monitor the operation status of the fuel system through pressure sensors and other control devices, and detect and report any abnormal conditions

In conclusion, the high pressure fuel pump is a key component in the engine fuel system. It is responsible for supplying and injecting fuel, maintaining appropriate pressure, and protecting the normal operation of the fuel system. It is a crucial part for engine performance, fuel economy, and emission control.
