电控柴油机除了会出现与传统柴油机相同的机械故障外,还会出现因电路系统、控制系统因素导致的软性故障。因此,对于电控柴油机而言,除了机械故障(如拉缸、烧瓦抱轴等)可以直接凭经验判断外,很多软性故障(如ECU故障、电路线束故障等)是不能凭经验解决问题的。这需要使用故障诊断仪器检测故障,并根据故障码找出故障原因后加以排除。因此,在诊断和排除电控柴油机故障时,诊断仪和 In addition to the electronic control diesel engine will appear the same with the traditional diesel engine mechanical failure, but also because of the circuit system, control system factors lead to soft fault. Therefore, in the case of electronically controlled diesel engines, many soft faults (such as ECU faults and circuit harness faults) can not be solved empirically except for mechanical faults (such as pulling cylinder, of. This requires the use of fault diagnostic equipment to detect faults, fault codes and find out the cause of the malfunction to be ruled out. Therefore, in the diagnosis and troubleshooting of electronically controlled diesel engines, diagnostic equipment and
