根据机油状态评定汽车部件技术状况的方法早就引起了使用人员的注意。因为这种方法比较简单,也不费力。它对诊断和预测车用发动机,其中包括易出故障、但又难以下手检修的主轴承和连杆轴承的技术状况具有特殊的意义。内燃机曲轴轴承的技术状况,可以根据曲轴箱中机油的腐蚀性的变化来评定,因为研究工作指出,机油的腐蚀性与发动机可靠性、耐 The method of assessing the technical condition of automotive components based on the condition of the oil has long drawn the attention of the user. Because this method is relatively simple and effortless. It is of special significance for diagnosing and predicting the condition of main engines and connecting rod bearings of vehicle engines, including those that are prone to failure but are difficult to service. The technical condition of crankshaft bearings for internal combustion engines can be assessed on the basis of changes in the corrosion of the oil in the crankcase as the research indicates that the corrosion of the oil and the reliability of the engine,
