增压压力对增压柴油机喷雾混合和着火的影响

The Influence of Supercharging Pressure on Fuel Spraying、Mixing and Ignition in Supercharging Diesel Engine

介绍了增压柴油机中增压压力对燃油喷雾混合过程和着火的影响。研究结果表明 ,柴油机增压可以改善燃油喷雾和油气混合过程。提高增压压力可以减少燃烧室壁面附近的燃油堆积 ,加强燃油和空气的空间混合 ,改善油气混合质量并缩短着火延迟期 。

WT5”BZ] This paper reports an investigation of the influence of supercharging pressure on spraying、mixing and ignition in a supercharged diesel engine.The results of the investigation show that using supercharging,mixing of both fuel spray and air can be improved.By increasing supercharging pressure the accumulation of the fuel near the wall of combustion chamber can be decreased,and the mixing of both fuel spray and air in the space of combustion chamber can be strengthened.Ignition delay is also shortened,and the ignition points are removed into the centre area of combustion chamber.
