摘要：
This paper presents the dynamic characteristics of the fuel injection system in gasoline engine. Through AMESim software, it analyzes the pressure pulsations due to the excitation by the injector opening and closing with regular interval. The simulation model is validated by experiments. Then it compares the pressure pulsations of the system with and without damper. The results show that damper can attenuate the pulsation effectively. Based on this, the feature parameters of the damper are simulated with respect to its effect on attenuation. Proper parameters selection can result in better pressure pulsation control.
