汽车正常怠速转速多少?
What is the normal idle speed of the car?
一般来说,汽车正常怠速转速为800转左右,因为这一状态并不需要太多的动力,所以这样的转速能带动基本的油水运行;需要注意的是,汽车刚启动的时候,转速会飙升到1500转左右,这种情况是正常的,汽车需要高转速让 发动机 尽快达到正常的工况,需要较浓的混合气,因此进气量和喷油量都会加大,导致转速偏高,一般半分钟左右就回落到1000转以下了,冬天的回落时间会稍长一些。
Generally speaking, the normal idle speed of the car is about 800 rpm, because this state does not need too much power, so this speed can drive the basic oil-water operation; It should be noted that when the car is just started, the speed will soar to about 1500 rpm, which is normal. The car needs high speed to make the engine reach the normal working condition as soon as possible, and it needs a thicker mixture. Therefore, the intake and injection volume will increase, resulting in a high speed, which generally falls below 1000 rpm in half a minute, The fall time in winter will be a little longer.

汽车省油的转速是多少?
What is the fuel saving speed of the car?
省油的转速为1500转左右,因车而异,因为现在 涡轮 增压车型越来越普及,涡轮是需要等到一定转速才会介入,动力才会真 正爆发出来,也就是我们常说大 扭矩 的输出区间,常见的就是1500转,只要我们行驶的时候,基本保持在这一转速下,既能确保动力的充沛,也不至于 油耗过高,可以说是平衡经济的转速了。
The speed of fuel saving is about 1500 rpm, which varies with the car. Now, turbocharged models are becoming more and more popular. The turbine needs to wait until a certain speed to get involved, and then the power will really break out. That is, we often say that the output range of high torque is 1500 rpm. We only need to keep it at this speed when driving, so as to ensure abundant power, The fuel consumption will not be too high, which can be said to be a balanced economic speed.
