一些疑问关于发动机的马力.

不知道你注意到没有,每辆车在标明发动机马力和扭力的时候,都标明了发动机的转速,而通常来说,这个转速都是很高的,至少在5500转以上.
而我们平时开车,特别是自动档的,根本就没机会让发动机在5000以上.
那么发动机的马力在3000转,4000,5000,这些我们能感觉到的转速上,马力和扭力到底是多少呢?汽车厂有意的隐瞒了,大家只能自己去猜.
而更有意思的是,几乎所有的车,特别是相同级别的车之间,在表明马力和扭力的时候,都把转速有意识的避免和别的车一样.虽然我不是学发动机专业的,但我明确一点,发动机的马力输出,如果用曲线表明的话,它绝对不是线性的,也就是说,发动机的马力和扭力,不能用每一转多少马力来计算.

我个人认为,马力这东西,对轿车没有什么实际意义,马力大,只是表示这车拉得多,载重好,而我们开车比较注重的是加速性能,而加速性能的好坏,是靠扭力大小来决定的.特别是低转速时的扭力.我的车和朋友的车比较,
我的是V6不是2.8 190HP/6000, 206lb/3200, 朋友的是V6 3.0, 240HP/6250, 212lb/5000,虽然马力低很多,但开起来加速快很多.
为什么没有一个组织,把这些指标都统一起来,分别标明2K,3K,4K,5K,6K时候,到底有多少马力,多少扭力呢?
可能是商业目的吧.
欢迎大师指正.
