一般说,运行中的偶然爆震现象可以通过适当调整加以解决。对于修理中因某些技术条件未严格控制而产生的爆震,则不可能用调整的方法排除。若此种现象让其存在,不仅使发动机的动力性下降,燃料经济性变坏,而且由于“敲缸”、发动机过热、严重积炭等因素会加速发动机的损坏,且车辆使用性能变差。因此,在发动机大修过程中,应十分重视与严格控制有关的技术条件。 In general, the accidental knocking in operation can be solved by proper adjustment. For repairs due to some technical conditions are not strictly controlled knock, it is impossible to rule out the use of adjustments. If this phenomenon is allowed to exist, not only the engine power is reduced, the fuel economy is deteriorated, but also due to “knock cylinder”, the engine overheating, serious coke and other factors will accelerate the engine damage, and the vehicle performance deterioration. Therefore, in the engine overhaul process, should pay great attention to the strict control of the technical conditions.
