摘　　要：内燃机性能检测能力验证是对内燃机性能检测结果进行质量控制的常用方法,是获得内燃机检测实验室认可的必要条件。近几年的内燃机性能检测能力验证活动在实施过程中存在一些典型性和普遍性问题,分析和识别这些影响结果的因素,对于控制和提高内燃机检测质量有着极其重要的意义。本文通过总结内燃机性能检测能力验证活动经验、结合实际案例,从试验人员、测试设备、样机、试验方法、试验条件、结果检查6方面分析了导致内燃机性能检测能力验证结果不满意的因素,探讨了加强内燃机性能检测过程质量控制、提高能力验证结果满意水平的措施。Proficiency testing for internal combustion engine performance is commonly used for quality control of internal combustion engine performance inspection results and is a necessary condition to obtain the accreditation of internal combustion engine laboratory. In recent years, there are some typical and universal problems in the proficiency testing. Analyzing and identifying these factors is very important for controlling and improving the testing quality of internal combustion engines. In this paper, the reasons for the dissatisfaction of the results of proficiency testing of internal combustion engine performance are analyzed from 6 aspects： the tester, the test equipment, the prototype, the test method, the test condition and the result check and the measures to improve the quality control for internal combustion engine performance test and the proficiency testing results are discussed through summarizing the experience of proficiency testing and combining with practical cases.
