扫气对直喷增压汽油机性能影响的试验研究

Experimental investigation of scavenging effect on direct injection turbocharged gasoline engine

介绍了试验装置的布置及方案，重点论述了中低转速大负荷区域不同气门重叠角形成的扫气对直喷增压汽油机充气效率、燃烧及排放性能的影响。

This paper introduces the layout and scheme of the test device, focusing on the direct injection turboeharged gasoline engine volumetric efficiency of scavenging the low speed and heavy load regions of different valve overlap formation, combustion and emission performance.
