| Abstract: | Five methods of dilution factor(DF) calculation are outlined in this article.Five groups of typical cycle test data of an automotive diesel engine in steady test cycle is obtained based on constant volume dilution sampling system,and the dilution factors in each cycle are calculated and analyzed,then the difference of four DFs based on pollution concentration and DFFlow based on flow are compared and analyzed,and the effect thereof on CO2 and HC correction results as well as on fuel consumption calculation ... |
