What is the function of the fuel pressure regulator?
1 Answers
The function of the fuel pressure regulator: 1. Adjust the fuel pressure in the fuel supply system to maintain balance within the system; 2. Buffer the pressure fluctuations generated during fuel supply, ensuring the engine operates normally. The fuel pressure regulator consists of components such as springs, valve bodies, and valves, and is usually installed at one end of the fuel distribution pipe. Essentially, the fuel pressure regulator is an overflow valve controlled by a diaphragm, which divides it into an upper spring chamber and a lower fuel chamber. The diaphragm adjusts the opening of the overflow valve to maintain pressure balance between the two chambers. Precautions regarding automotive fuel: 1. Try to use high-quality fuel when refueling; 2. Do not mix different types of fuel; 3. Avoid waiting until the fuel tank is completely empty before refueling; 4. Do not overfill the tank when refueling.
