Spring use and maintenance common sense oil outlet valve spring

Spring use and maintenance common sense oil outlet valve spring
After the spring force of the oil outlet valve decreases. It will cause serious internal leakage of high-pressure oil, reduce the residual pressure in the high-pressure oil pipe, and the oil outlet valve does not seat quickly, resulting in the reduction and instability of fuel supply, and the engine is unable to work and “travel”. In addition, it will make the fuel injector start to spray powerless, cut off the fuel not simply, and drop after the phenomenon, resulting in combustion deterioration, engine overheating, exhaust smoke. Therefore, the spring of the oil outlet valve should be replaced after 3600-4500 h of use. If there is bending deformation, it should be replaced in time.
