摘要

本文对某中型载重汽车用压燃式发动机的可靠性进行了分析。可靠性评估的标准是燃烧室密封性的降低。该分析基于5辆卡车在长期运行期间进行的压缩压力试验和泄漏试验的结果。首先确定实验生存函数，然后确定与经验函数拟合的连续可靠度函数和故障率函数。

Reliability assessment of a truck engine based on measurements of combustion chamber tightness

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.
