Reliability Assessment of A Truck Engine Based on Measurements of Combustion Chamber Tightness

摘要：

　　The article shows an analysis of the reliability of a compression-ignition engine used in a medium duty truck.The criterion for the reliability assessment was the decrease in combustion chamber tightness.The analysis was based on the results of compression pressure tests and leak-down tests conducted during a long-term operation of 5 trucks.Experimental survival functions and then continuous reliability functions,fitted to the empirical ones,were determined along with the failure rate functions.
