摘要
由喷射燃油撞壁产生的进气道内油膜是导致过渡工况空燃比控制偏差的主要原因。本文对小型汽油机进气道内燃油雾化和蒸发模型进行了分析,总结出了影响油滴油膜形成和蒸发的主要因素。
The wall tion under engine are transient film generated by the impinging sprays is the main reason of air-fuel ration control deviaconditions. The fuel diffusion and vaporization model in the intake port of small gasoline analyzed, and the key factors affecting the formation of droplet and film are generalized.
