The use of a Petrol Car oil pump is to pressurize the oil in the oil pan to the filter, and to ensure that the oil can still be reliably delivered to each lubricating oil channel and the friction surface of each moving part after passing through the filter. When the Petrol Car engine is working, the Petrol Car oil pump works continuously to ensure that the oil circulates continuously in the lubricating oil circuit. If it is damaged, there may be abnormal sounds, noise, and power attenuation. If it is not handled in time, it may even cause cylinder pulling and failure to start, and the Petrol Car engine will be completely scrapped!
1. Acceleration is weak, and there is a setback when refueling urgently
2. It is difficult to start when starting, and it takes a long time to turn the key
3. Abnormal sound, there is a buzzing sound when driving.
4. The Petrol Car engine fault light is on.
5. The Petrol Car engine shakes.
① There are bubbles in the oil cup of the Petrol Car pump, and the oil level in the oil cup is lowered; or the output Petrol Car is loose and contains bubbles, which means that there is air infiltration in the pipeline from the Petrol Car pump to the Petrol Car tank. You should focus on checking whether the oil cup gasket is sealed and whether the Petrol Car pump oil inlet pipe joint is damaged.
② There are no bubbles in the Petrol Car pump oil cup, which is often caused by serious wear of the moving parts of the rocker arm group and the diaphragm spring is too soft, resulting in insufficient stroke and pressure.
③ Insufficient fuel supply after shutdown and gliding. This kind of fault is mostly caused by air resistance. Before shutdown and gliding, Hongqi Car often run under heavy load, so the engine temperature of Hongqi Car is often high; after shutdown, the water pump and fan stop working, and the heat dissipation conditions become worse.
