电控单体泵小循环喷油量的关键影响因素研究
Key influence factors of small cycle fuel injection quantity for an electronic unit pump system of diesel engines
摘要
Abstract
An electronic unit pump ( EUP ) is a fuel injection system which can satisfy the requirement of diesel en⁃gine's power performance and emission characteristics. In order to investigate the fluctuation in small cycle fuel in⁃jection quantity of the diesel engine at low loads, a numerical model of the EUP system was built in the AMESim environment and its accuracy was verified by experiment. The quantitative relationship between the fluctuation in minorcycle fuel injection quantity and every key parameter was studied in different cam speeds. The quantitative percentage index of the different parameters is obtained. At the same time, combining the central composite design experimental method, and taking into account the interaction of different characteristic factors, the correlation coef⁃ficients of different factors and minor cycle fuel injection quantity are revealed after the correlation analysis.关键词
