摘　　要：应用GT-Power软件建立某发动机工作过程的仿真模型,模拟发动机进排气管内流体流速和压力随曲轴转角变化的情况,获得了发动机的气缸压力、温度、功率、扭矩和燃油消耗率等随发动机转速之间的变化规律,并进行详细分析。计算结果可为发动机的设计和性能改善提供一定的理论参考。The simulated model of an engine working process was built based on GT-Power. The fluid velocity and the dynamic pressure in the intake and exhaust manifolds with the change of crank angle were simulated. The evolution of the cylinder pressure, temperature, power, torque and fuel consumption with the change of engine speed was obtained, and analyzed in detail. These computed result is valuable for the designing and improving of the engine.
