摘要：
Electronically controlled assembly pump (ECAP) is a hydraulic and electro-magnetic driving assembling product, and is an electronic unit pump (EUP) fuel injection system that meets emission regulation and fuel economy. By the comparison between the numerical simulation and experiments, it is concluded that the AMESim simulated model can precisely estimate the fuel injection system parameters under all operating conditions. Comparative analysis at various pump pressure, injector pressure and fuel injection quantity showed that the ECAP characteristic maps including fuel injection timing, fuel injection quantity and fuel injection pressure were obtained. NOx of 4.74 g/(kW&middoth) and PM of 0.085 g/(kW&middoth) were obtained in Yuchai 4110 diesel engine, and this meets the Euro III ESC emission regulation.
