| Summary: | Common rail diesel engines with electronic fuel injection can accurately meter the fuel injection quantity with more accurate fuel injection control capability. In this work a common rail fuel injection system of a single cylinder diesel engine has been proposed and the important parameters like injection pressure, energizing time and high pressure pipes diameter and length are designed such that to be compatible with the engine basic design in case of pressure waves and injected mass variations. A one-dimensional approach has been used to model the injector using AMESim code in which Adiabatic models have been used to model injector system. Injected mass quantity has been calculated for different working point of fuel injection system that can be utilized as engine electronic control maps as inlet parameters. Results indicated that pressure fluctuation at the injector inlet is increased by decreasing pipe diameter while tube length has no significant effect on pressure waves. It is also shows that using biodiesel as fuel will lead to decrease in injection quantity but there is no significant impact on pressure fluctuations. |
