断火试验。打开加机油口盖,提高发动机转速至响声明显、冒烟处稳住。若某缸断火后响声减弱或消失,且加机油口处的冒烟量明显减少,说明漏气异响是该缸发出。
加机油。为了进一步是否是活塞敲缸响,可将发动机熄火,卸下有响声汽缸的喷油器, 往汽缸内倒少许机油,并用手摇把或起动机转动曲轴数圈,使机油布满在汽缸壁与活塞之间。然后装上喷油器,启动发动机,若响声短时间内减弱或消失,过一会儿又重新出现,则可为是活塞敲缸响。
正时齿轮响
故障现象
有的有节奏,有的无节奏。在有节奏的响声中,有的属于间响,有的属于连响。转速越高,响声往往越大。使用单缸断火,响声不减弱。
齿轮齿面碰伤、脱层或轮齿断裂;
齿轮在曲轴或凸轮轴上松动或脱出;
曲轴或凸轮轴轴向间隙过大;
重新装配一对正时齿轮时,改变了原来的啮合位置;
未成对更换齿轮。
诊断方法
诊断的方法有两种:一种是变换油门开度法,另一种是听诊法。在配合使用上述两种方法的同时,要结合以下情况分别进行判断。
诊断中若发现响声是无节奏的,且在发动机怠速运转时发出“嘎啦、嘎啦”的响声,中速时 响的更为明显,高速时响声变得杂乱并带有破碎声,响声时正时齿轮室盖处有振动,这有可能 是齿轮啮合间隙太大造成的。
如果出现一种连续不断的“嗷——”的响声,发动机转速越高是响声越大, 并且经证实该机更换过正时齿轮,则有可能是齿轮啮合过紧的缘故。
如果出现有节奏的“哽、哽、哽”的响声,发动机转速越高时响声越大,则可能是齿轮啮合间隙不均造成。若响声为连响,则故障出在曲轴正时齿轮上;若响声为间响,则故障出在凸轮轴正时齿轮上。
若响声是有节奏的,发动机怠速运转时能听到“嗒啦、嗒啦”的声音,中速以上时又变为紧 凑的“嗒、嗒、嗒”的响声,这往往是金属齿轮齿面碰伤以后出现的响声,如果故障在曲轴正时齿轮 上为连响,在凸轮轴正时齿轮上为间响。
