车友朋友们大家好,欢迎收看肖哥说车,今天跟大家聊聊跑高速时发动机转速是不是越低越好?
走高速时,一般都会将时速控制在100-120Km/h左右,而转速越低发动机就越好这个说法从某种角度上来说也是对的,但有几点需要补充。
挡位越多越省油
首先时速在120Km/h转速度更低说明汽车的动力更好,巡航省油的效果更明显,但这里也不能忘记变速箱的功劳。大家都知道发动机产生的动力是通过变速箱的传递到达车轮的,而变速箱的齿比也决定了动力的利用率,理论上来说变速箱的档位越多,动力的利用率越高。
举个例子,就好比我们爬楼梯,发动机就像我们的腿,如果发动机的动力比较弱,就相当于一个人的力气很小,只能爬一些高度比较低的台阶一阶一阶的向上爬,而如果是一个身体强壮的运动员爬楼梯,他完全可以一步两个台阶,甚至一步四个台阶的走楼梯,并且还不费力,此时变速箱就像是可以改变高度的台阶,给一些身体素质比较差的人更低的台阶,让他每走一步都不需要太费力,而给运动员一些更高的台阶,让他能走得更快更有效率,那么如果再加上一个条件,就是让他们用同样的时间到达楼顶的话,身体素质弱的人只能通过加快自己的步伐频率来提高速度是一样的道理。
挡位多的变速箱带来最直接的好处就是省油,更多的齿比变化,更高的动力利用率,并且动力更强的发动机转速越低,活塞往返做功的次数以及发动机内部的摩擦次数更少,热效率更高,也是省油的根本所在。
变速箱的挡位多的另一个好处就是舒适性更好,换挡时发动机的转速没有太大的下降,动力的接驳更平顺,顿挫感越小,乘坐越舒适,再匹配上动力适合的发动机,就可以算上是一辆好车了。
从以上几点简单的介绍了一下高速行驶发动机的转速是不是越低越好,如果您有什么不同的看法欢迎关注肖哥说车或在评论区留言讨论,我们明天再见。
