    摘要：对汽油机燃烧室紧凑性面容比A/V值进行分析,讨论了其局限性,以及在特殊条件下不适用性。另外提出了新的内燃机燃烧室紧凑性的衡量方法,以面面比S/A代替A/V,分析其适用于不同形状,不同燃烧室结构尺寸的各个燃烧室进行紧凑性及火焰传播距离的比较。

      Abstract: Surface to volume ratio A/V for compactness of gasoline engine combustion chamber is analyzed and limitations and non-applicability at special condition is discussed.In addition,a new measurement of compactness of internal combustion engine combustion chamber is described.S/A in replace of A/V is adopted for analysis and comparison of its application in different shapes,different sizes of various combustor firebox structure of the tight and the flame spread distance.

      Keywords: Surface to Surface Ratio;Combustion Chamber Area of Piston;The Same Volume Comparisons
