进气不足,排气不干净、密封性能下降、喷油压力过低、供油过早或过晚以及润滑油的数量和质量不符合要求等,都会导致柴油机的动力性与经济性下降。治理的措施主要有:定期清洗空气滤清器滤芯,清除进、排气管道和消声器隔音板上的污物和积炭;定期检查、调整气门间隙,在配气相位误差不大时适当减小气门间隙来弥补凸轮等零件磨损对配气相位的影响,保证配气正时;定期检查气门弹簧的技术状态以及气门与气门座的密封性,必要
Inadequate intake, exhaust is not clean, sealing performance degradation, injection pressure is too low, too early or too late, and the oil quantity and quality do not meet the requirements, etc., will lead to the decline of the dynamic and economic diesel engine. The main measures are: regular cleaning of air filter element, clear the intake and exhaust pipe and muffler noise board and the coke deposition; regular inspection, adjust the valve clearance, the gas phase error is not appropriate to reduce Valve clearance to compensate for the wear of parts such as cams on the valve phase, to ensure that the valve timing; regular inspection of the technical state of the valve spring and the valve seat and the valve seal is necessary
