汽油机燃烧室紧凑性评价参数分析

Analysis of Compact Evaluation Parameter for Gasoline Engine Combustion Chamber

对燃烧室紧凑性评价参数面容比A/V值进行了分析,讨论了其局限性。提出了新的内燃机燃烧室紧凑性的衡量方法,即面面比S/A,在等容积条件下,进行了各种燃烧室紧凑性及火焰传播距离的比较。

The paper analysed surface to volume ratio A/V of gasoline engine combustion chamber and discussed its limitations; surements of combustion chamber compact ;compared the compact chambers and the flame spread distance in the same volume. compact evaluation parameter for presented S/A as the new meafeature of the various combustion chambers and the flame spread distance in the same volume.
