目前,汽车主要是通过制定维修计划来进行定期保养的,其缺点是难以及时发现故障,而且不能记录车辆工作过程中数据的变化规律,从而给其故障的预测、预防、诊断与排除带来了困难。 随着检测水平及检测精度的日益提高,对机油定期抽样检验分析已成为一种行之有效的车辆预防性保养方法。这种方法是从车辆不同部位抽取用过的机油油样进行一系列诊断试验并加以分析,测量和比较油中机件磨损材料的含量,依据这些数据,来判断发动机、变速箱、
At present, automobiles are regularly maintained through the formulation of maintenance plans. The disadvantage is that it is difficult to find faults in time and can not record the changing laws of the data during the working process of vehicles, thus bringing about the prediction, prevention, diagnosis and elimination of faults difficult. With the increasing level of detection and detection accuracy, periodic sampling inspection and analysis of oil has become an effective method of preventive maintenance of vehicles. In this method, a series of diagnostic tests are taken from different parts of the vehicle for analysis of the used oil samples to measure and compare the wear material content in the oil components. Based on these data, the judgment of the engine, transmission,
