Daily Maintenance and Maintenance of Diesel Car Fuel Injection Pumps

Ms. Zhang, Gogol Street, Nangang District Q: How should the fuel pump of a diesel car be maintained to prolong the service life?

Liu workers A: The daily use of fuel pump maintenance should pay attention to the following aspects:

1. To choose a higher alkane, better evaporation, freezing point and viscosity appropriate, non-moisture and mechanical impurities of diesel. Fuel injection pump is directly lubricated and cooled by the fuel, the fuel impurities, poor quality will make the fuel pump early abnormal wear and tear, and shorten the life of the fuel pump; too much fuel in the water injection pump is fatal, Can cause the spray pump to work immediately. In the diesel before filling, to go through full precipitation, precipitation time is best in more than 3 days, it is recommended to regular large gas station refueling.

2. To use in line with the requirements of the original diesel filter. As long as the oil to meet the national standard, according to the requirements of water, there will be no damage caused by water on the pump. Car owners should learn to do their own hands to the diesel car diesel filter water, to develop a good habit of often give their car water, through their own hands to reduce the water on the diesel fuel pump on the serious damage. At least every 1000 km to the diesel filter water once, diesel water content is too large, depending on the specific circumstances to increase the number of water.

3. Use the manufacturer's recommended fuel additives as required. Such additives generally have good lubrication, cleaning, water removal, rust and other functions, the injector, fuel injection pump, the engine has great benefits. Use the following method when used:

(1) When less than 10 liters of fuel is in the tank, add a tank of additive to the tank and fill it up with diesel.

(2) Six new cans should be used continuously during the new car period.

(3) Use 3 cans continuously every 10,000 km.

(4) If it is found that the added diesel oil is of poor quality and engine noise is increased, additives should be used continuously.
