过滤盒.试验方法.耐流率循环变化的性能 - Coefficient of cyclic variation
循环变动系数 - Experimental investigation shows that methanol engine cyclic variations mainly depend on the length of ignition delay and the proper mixture stratified concentration distribution in cylinder
试验结果表明，甲醇发动机的燃烧循环变动主要取决于着火延迟期的长短和缸内混合气层状浓度分布是否合理。 - Reducing ignition delay and the ideal mixture stratified concentration distribution near the spark plug gap and the combustion chamber can reduce methanol engine combustion cyclic variations , and modify engine performances
缩短着火延迟期，或在火花塞跳火区域及燃烧室内获得理想的混合气层状浓度分布均可降低甲醇发动机燃烧循环变动，使发动机性能得以改善。
