摘    要:本文研究了车用压燃式发动机全负荷稳定转速和自由加速试验可见污染物排放之间的关系。采用不透光仪对19种型号188台样机进行了可见污染物试验。在大量的试验数据基础上,用数学统计的方法,对试验数据进行线性回归、相关系数和方差分析来研究两种可见污染物之间的内在联系,获得了一些有意义的信息和结果。

关 键 词:排放统计  汽车  压燃式发动机  可见污染物

Abstract:This paper describes a study of the relations between the visible pollutants from automotive compression ignition(C.I.)engines in the test at steady speeds under full-load and the test under free acceleration.For this purpose,the experiments of visible pollutants from 188 engines of 19 different models have been done by using two types of opacimeters.Based on the experiment data,the analyses of linear regression,correlation coefficient and variance analysis have been made to study the inherent relations between visible pollutants in free-acceleration test and full-load test. Some important information and results have been obtained.
Keywords:Vehicle Compression ignition engine Visible pollutants Emission
