What is the normal range for oil pressure?
1 Answers
Automotive oil pressure typically ranges between 284-325 kPa (41-47 psi). Installed inside the fuel tank and connected to the fuel delivery assembly, the electric fuel pump delivers fuel through the pipeline filter to the fuel rail assembly. The fuel pump is designed to provide fuel pressure higher than the regulated pressure required by the injectors, with excess fuel returning to the tank via the return line. The fuel pump test terminal is located in the engine compartment; when the engine is off, applying battery voltage to the test terminal can start the fuel pump. Below are additional details about oil pressure: 1. The oil pressure regulator is a diaphragm-controlled overflow valve. 2. When the fuel chamber pressure exceeds the combined force of the spring pressure and vacuum pressure, the diaphragm arches upward, opening the regulator valve and allowing fuel to flow back to the tank through the return port via the ball valve.
