故障现象
一辆2012年产上汽大众POLO 1.6轿车,搭载CPJ发动机,行驶里程11万km。用户反映该车后部有异响。
检查分析
维修人员试车发现,该车的异响是从右后部位发出的。贴近右后轮仔细听,像是燃油泵发出的声音。根据经验判断,燃油泵很快就要失效了,这会导致车辆无法行驶。
经用户同意后,更换了燃油泵。可是结果令人失望,响声丝毫没有减弱。用听诊器听,还是燃油泵的声音。恰好在这个时候有一辆同款车来做保养,对比燃油泵的声音,那辆车就小得多。仔细观察发现,那辆车的燃油滤清器与故障车的不一样,在进油口处没有一个圆形凸起(图3)。
图3 正常车的滤清器
查阅资料得知,燃油滤清器的凸起部分是内置式油压调节器(图4)。该车的油压调节器是在油轨上安装的,这样一来滤清器上的调压器便成了多余的。2个油压调节器互相影响,是导致异响的根本原因。

故障排除
正确更换燃油滤清器,试车确认故障排除。
