What is the normal oil pressure for a car?
1 Answers
The normal oil pressure for a car is around 300kpa. The reasons for abnormal oil pressure include: 1. Insufficient oil in the oil pan, oil becoming thin, deteriorated, or losing viscosity; 2. Severe wear or improper assembly of the oil pump; 3. Severe clogging of the oil pickup screen or filter by sludge, making it difficult for oil to enter the main oil passage; 4. Poor sealing of the oil pump inlet pipe joint, causing severe air suction; 5. Loosening of the oil pan drain plug or breakage/cracking of the oil pipe, leading to significant oil leakage. The oil pressure regulator is installed at one end of the fuel distribution pipe, and its functions are: 1. To regulate the fuel pressure in the supply system, maintaining a constant difference of 300kpa between the system oil pressure and the intake manifold pressure; 2. To buffer the pressure pulsations generated by the fuel pump during supply and the pressure fluctuations caused by intermittent injection from the injectors.
