【 摘 要 】

This article discusses the method and results of accelerated tests of crankshaft bearings of the compression ignition engine, carried out to determine the possibility of modernising the basic engine model and improving the methods of friction joint diagnostics. The essence of the method consists in changing the operating conditions of the crankshaft bearings of one of the engine cylinders. This increases the bearing load and causes changes in the engine oil temperature. The bearing condition was monitored non-invasively by determining the share of wear products in the oil samples. The results obtained from the tests have shown that on the basis of oil analysis for the presence of wear products, the cause of engine failure related to the acceptable wear of engine friction pairs can be clearly identified and located.
