What problems will occur if the oil pump of the car breaks down?

The performance of a broken gasoline pump

1. Weak acceleration and frustration at times of rapid refueling

2. It is difficult to start the machine, and it takes a long time to type the key

3. Abnormal sound, there is a buzzing sound when driving.

4. The engine failure light is on

5. Engine jitter

The common fault of gasoline pump is that the oil supply is insufficient when the car goes uphill. The reasons are as follows:

(1) gasoline pump oil cup bubble, at the same time oil cup oil surface reduced; Or the output of gasoline is loose, and with bubbles, gasoline pump to the gasoline tank in the pipeline there is air infiltration. It is important to check whether the oil cup gasket is sealed and whether the oil pump inlet pipe joint is damaged.

(2) gasoline pump oil cup without bubbles, often due to rocker arm group moving parts seriously wear, diaphragm spring is too soft, resulting in insufficient travel and pressure.

(3) flamed slide after insufficient oil supply, this kind of fault is caused by air resistance. Before stalling taxi, the car often runs under heavy load, so the engine temperature is often on the high side; After flame out, because the pump and fan are stopped working, cooling conditions become worse.

Gasoline affected by high temperature, so that part of its light volatile gas, coexist in the gasoline pump, the destruction of the oil stroke of the vacuum, increase the flow of gasoline resistance. When the amount of gas produced per unit time is greater than the exhaust volume of the gasoline pump, it will lead to no oil.
