1 我国汽车检测技术的发展及应用现状表示汽车性能的参数众多,随着汽车行驶路程的延续,有的明显变差,如,动力性、经济性、安全性、操纵稳定性、可靠性、噪声及排放污染状况等。汽车的某一性能变差反映了汽车某一总成或系统状况不佳,但不能表示汽车的总体状况。因此,要判明汽车的总体技术状况,必须检测与技术状况变化密切相关的多项性能参数,即对汽车实施综合性能检测。
1 The development and application status of automotive inspection technology in our country There are many parameters that indicate the performance of automobile. With the continuation of automobile driving distance, some of them obviously deteriorate, such as power, economy, safety, handling stability, reliability, noise And discharge pollution status. Some deterioration of a car’s performance reflects a car’s assembly or system in poor condition, but can not indicate the overall condition of the car. Therefore, to determine the overall technical condition of a car, it is necessary to detect a number of performance parameters that are closely related to the change of technical conditions, that is, perform comprehensive performance tests on the car.
