在用车排放污染超标往往不是一个孤立的因素造成的,也不可能采用一种简单的方法,例如安装某一种产品就能解决的问题。对于排放超标车必须对其运行情况进行全面的诊断,确定排放超标的原因是调整不当,还是由于某些零部件出现故障所致,对症施治,才能达到治本的目的。 It is often not an isolated factor that excessive emission of pollutants in vehicles is used. It is also impossible to adopt a simple method, for example, a problem that can be solved by installing a certain product. For the emission of over-the-car must conduct a comprehensive diagnosis of its operation to determine the cause of excessive emissions due to improper adjustment, or due to some parts of the failure caused by symptomatic treatment, in order to achieve a permanent cure.
