What is the normal fuel pressure for a car?

The normal fuel pressure for a car is between 300-350kPa (the specified pressure may vary for different vehicle models). Below is relevant information: 1. There are two types of automotive fuel systems: full return systems and partial return systems. The difference is that full return systems have a return line on the fuel rail, while partial return systems do not. 2. Turn the ignition switch on (without starting the engine) to operate the electric fuel pump. The fuel pressure at this time should meet technical requirements, generally fluctuating around 0.3MPa. 3. Clamp the return hose, and the reading on the pressure gauge will be the fuel pump's maximum supply pressure. This value should comply with the vehicle's technical requirements, typically 2~3 times the working pressure, i.e., 0.5~0.75MPa.

How to Adjust the Tightness of a Door Check Strap?

Door check strap adjustment methods are as follows: 1、Design and manufacturing process issues: Severe misalignment between the door hinge axis and the check strap rotation axis. It is recommended to control the parallelism within 3 degrees and monitor the door hinges. 2、Wear caused by improper assembly during use or door sagging: Loosen all installation screws of the check strap, open and close the door repeatedly more than 5 times, then tighten the screws. 3、Ensure the friction surface of the check strap is lubricated. Misalignment between the door hinge axis and check strap rotation axis can also be resolved through adjustment, though this requires higher technical expertise and must be addressed empirically.
