车辆使用过程中总会出现方方面面的故障,并且机械、电控、燃油供给、润滑和冷却等方面的故障交织在一起,而不是单一地发生在电控系统中,以致采用故障检测仪在车辆的故障自诊断系统中读不出故障,形成了所谓的疑难故障,破坏了发动机的整机性能,引起排气污染物超标。利用尾气分析仪检测尾气状况,可以确定车辆的“健康状况”和故障发生部位,从而准确、快速地排除故障。 There are always faults in the vehicle during use, and faults in the mechanical, electrical control, fuel supply, lubrication and cooling are intertwined rather than occurring singly in the electronic control system so that a fault detector can be used in the vehicle’s Fault self-diagnosis system can not read the fault, the formation of the so-called trouble, undermining the engine’s performance, causing excessive exhaust pollutants. Using the exhaust analyzer to detect the condition of the exhaust gas, the “health condition” of the vehicle and the location of the fault can be determined so as to accurately and quickly troubleshoot the fault.
