对应的发动机转速 meaning in English

corresponding engine speed

Long - hole and geometrical proportion type of mixing unit is finally adapted in lpg supply system , and power and torque output of lpg engine are improved by increasing compression ratio , and ignition characteristic is tried to adjusted to satisfy engine performance . meantime emission performance and noise level of lpg engine at full - throttle and other various part - throttle operations are tested and compared with former gasoline engine . ( 3 ) it is verified by engine dyno tests that lpg engine has better synthesized performance at aspects of power and torque , fuel economy , as well as emission than former gasoline engine
选择了等比例长孔式混合器控制空燃比；通过提高压缩比来弥补动力性的损失；以动力性为主控目标，对最大功率点、最大扭矩点、中等转速、最低转速点所对应的发动机转速做了点火特性的调节；通过空燃比的合理控制，直接改善发动机的动力性、经济和排放指标；作为对缸内燃烧过程的理论分析，进行了燃烧特性的实验测试；对原汽油机和新开发的液化石油气发动机，进行了外特性和部分负荷特性以及怠速的排放及噪声对比性测试。
