摘　　要：针对对置二冲程发动机的特殊性,本研究利用GT-power软件建立了相应的计算模型。计算结果表明,模型可以适于该类发动机的性能模拟计算。利用该模型对其进排气管内径、进气压力、供油提前角及油嘴方案等进行优化,结果表明:发动机的性能指标可以达到预期的目标,可为发动机的设计提供理论依据。The performance of the Opposed Two-Stroke Diesel Engine is calculated by GT-power software. A unique mathematical model is established to solve model problem. The results indicate that the performance of 2500r/min, full load can achieve the aim expected by optimizing on the inside diameter of intake and exhaust pipe, intake pressure, injection timing angle, and nozzle plans. A reasonable fuel system and combustion sys- tem is suggested to provide a theoretical basis for the design of the engine.
