摘 要：
在GT—POWER中建立某四缸点燃式LNG发动机模型并进行了仿真,研究不同燃料喷射温度对发动机指示功率、指示扭矩以及充气效率的影响。仿真结果表明,随着燃料喷射温度的增大,发动机的指示扭矩、指示功率和充气效率减小,经实验验证,LNG发动机合适的燃料喷射温度应为0~40℃。

摘 要：
A four cylinder spark ignition engine LNG model was set up in the GT—POWER and the simulation was conducted to research the effects of different fuel injection temperatures on the indicated torque,indicated power and volume efficiency.With the fuel temperature increases,indicated torque,indicated power and volume efficiency decrease.The experiment indicated that the appropriate LNG engine fuel injection temperature is 0~40℃.
