摘要
提高发动机压缩比是提高发动机功率的重要手段,同时将导致发动机爆震现象。通过对3种不同压缩比的发动机进行爆震试验,发现在整个转速区,压缩比为9.0的发动机爆震倾向最小,压缩比为9.3的发动机爆震倾向中等,压缩比为9.5的发动机爆震倾向最高。亦即得出压缩比大则发动机爆震倾向大的基本规律。
It is an important means to upgrade engine power by improving the engine compression ratio.However,this will cause engine knock.Experiments on engines with three compression ratios show that the tendency of engine knock is the lowest when the compression ratio is 9.0, the middle when it is 9.3,and the highest when it is 9.5 in the whole speed zone.Therefore, there is a direct relationship between engine compression ratio and engine knock.
