通用汽油机功率测量不确定度研究

Research for Measurement Uncertainty of General Gasoline Engine Power

按JJF1059-1999《测量不确定度评定与表示》规定的程序和方法,依据通用小型汽油机台架性能试验方法,对引起通用汽油机功率测量结果不确定度的因素逐一进行评定,计算各不确定度分量,找出不确定度主要因素,采取适当措施,提高通用汽油机功率测量结果的质量,促进测量不确定度评定工作在内燃机功率测量方面的应用。

According to performance test method of general utility small gasoline engine and evaluating method of uncertainty for measurement, the main factors effecting output power of general gasoline engine are evaluated one by one to calculate the component of uncertainty, and find out the main factor of uncertainty so as to take proper measures to raise the quality of power test for general gasoline engines and to promote the application of evaluating method of uncertainty for measurement in aspect of power test for internal combustion engine.
