Q:我一直有个疑问,为什么汽车发动机的最大功率和最大扭矩都不是出现在最大转速时?难道不是转速越高,发动机越有劲吗?A:发动机的最大扭矩主要与发动机进气系统、供油系统和点火系统的设计有关。在某一转速下,这些系统的性能匹配达到最佳,就可发出最大扭矩,我们称该发动机在这个转速下达到最大扭矩。发动机在不同的转速下,对应了不 Q: I always have a question, why the maximum engine power and maximum torque are not in the maximum speed? Do not the higher the speed, the more powerful the engine? A: The maximum engine torque and the engine intake system, for Oil system and ignition system design. At a certain speed, the best performance matching of these systems gives the maximum torque, which we call the maximum torque at this speed. The engine at different speeds, the corresponding no
