| 摘 要： | 阐述了分层评定理论,根据JJF 1059-1999《测量不确定度评定与表示》中的方法,介绍了如何评定在标定工况下由常柴TY295D柴油机改装后的多点喷射双燃料发动机的当量燃油消耗率的不确定度。通过分析,最后得到了当量燃油消耗率的扩展不确定度和准确度。

| Abstract: | Based on the multi-level evaluated theory,this article mainly illustrates how to evaluate the uncertainty of equivalent fuel consumption of the multi-port injection dual-fuel engine which is refit from the CHANG-CHAI TY295D diesel engine according to the requirements of the standard JJF1059-1999.Having analyzed the data,the expanded uncertainty and accuracy of the equivalent fuel consumption rate are obtained. |
