What is the normal high-pressure fuel pressure?

[LaKai]

High-pressure fuel pressure normally ranges between 300kpa to 350kpa. It should be noted that fuel pressure may vary depending on the vehicle model. Below is a partial introduction about the fuel pressure sensor: 1. Components: The fuel pressure sensor consists of a printed circuit board, sensor element, spacer block, and housing, among others. It contains a pressure chamber with a diaphragm featuring an overflow valve. The inner side of the diaphragm is a vacuum chamber, which houses a spring. 2. Working principle: Pressure acts directly on the diaphragm of the sensor, causing the diaphragm to produce micro-displacement proportional to the medium pressure. This changes the resistance of the sensor, which is detected by electronic circuits and converted into a standard signal corresponding to this pressure.
