在公路建设逐步向现代化、高速化方向发展的情况下,对车辆的技术性能、车容、排放等提出了高的要求,在高速公路迅速发展的今天,对汽车技术性能要求尤高。因此,对汽车技术状况实行强制检测,保障运行车辆技术状况良好是完全必要的。目前,我国汽车诊断技术工作大致有四种:运行车辆安全性年检;汽车维修质量监督检验;新车和改装车质量考核;运行车辆技术状况检验诊断。新车和改装车质量考核通常是在25000km 整车质量考核试验和2500km 整车质量抽查试验中进行的,它对各种状态下的数据进行检测评定,工作量
Under the circumstance that highway construction is gradually developing toward modernization and speeding up, high requirements are put forward on technical performance, vehicle capacity and emission of vehicles. In the rapid development of expressway today, the technical performance of vehicles is particularly demanding. Therefore, it is absolutely necessary to impose mandatory inspection on the technical condition of the vehicle and ensure the technical condition of the running vehicle is good. At present, there are roughly four kinds of automobile diagnostic technology work in our country: annual inspection of running vehicle safety; supervision and inspection of vehicle maintenance quality; quality assessment of new and modified vehicles; inspection and diagnosis of technical condition of running vehicles. New car and modified car quality assessment is usually carried out in 25000km vehicle quality test and 2500km vehicle quality checks carried out in the test, it tests the data under various conditions, the workload
