What is the function of the engine fuel pressure regulator?

[ColemanLynn]

The function of the engine fuel pressure regulator is to maintain a constant pressure within the fuel line. If the fuel pressure is too low, the fuel injector will spray fuel weakly or not at all. If the fuel pressure is too high, it can damage the fuel line or the fuel injector. The working principle is that fuel is pressurized by the fuel pump and supplied to the fuel injector. When the fuel injector's solenoid valve opens, the high-pressure fuel is sprayed into the intake manifold, forming a mist-like fuel spray that mixes the fuel with air. The following is an introduction to the engine: 1. Definition and classification of the engine: An engine is a machine that converts other forms of energy into mechanical energy. Current engines are divided into internal combustion engines, external combustion engines, jet engines, and electric motors. 2. The birthplace of the engine: The engine is an important component of a vehicle. The earliest engine was born in the UK. 3. Methods to distinguish engines: The parameter used to distinguish engines is the engine displacement. The larger the displacement, the stronger the engine's power output and performance.
