摘 要: 本文介绍了将FAI喷射技术应用到缸内直喷二冲程发动机上以改善二冲程摩托车发动机的排放和油耗的有关问题 ,并进行了初步的试验研究。结果表明 ,在二冲程发动机缸内直喷系统中 ,喷油量和喷油提前角是非常敏感的控制参数 ,点火相位也对发动机性能有影响 ,在这些参数控制合适时 ,该发动机的油耗和排放可接近于四冲程摩托车发动机。 This paper introduces application of FAI injection technology to direct injection two stroke engine to improve engines emission and fuel consumption. And primary experiment study has been made. The result indicates injection and injection timing are very sensitive parameters, and ignition timing also has influence on the engine performance. When these parameters are suited, the engines emission and fuel consumption can be close to four stroke engine.
