汽車如何找準換擋時機 ？

很多新手不知道該什么時候換擋，經常會出現低擋位高轉速的情況。正確的換擋應該是在汽車起步之后，隨著發動機轉速增加，配合不同車速，換入相應擋位。
Many novices don't know when to shift, and often have low gear and high speed. The correct shift should be in the car after starting, with the increase of engine speed, with different speeds, into the corresponding gear.
通常，當轉速提高到一定程度，發動機工作噪聲就會加大，此時就必須升擋，換擋的時機一般在發動機轉速為2 500～3 000 r／min之間(不同性能的發動機會有所不同，使用時要先閱讀使用手冊)。新手若沒有學會根據發動機聲音變化換擋，可在保證安全的情況下觀察一下轉速表，感受在換擋轉速時發動機的聲音變化。減速換擋原理相同，但應注意當車速過快時，先將車速降低到相應范圍內，然后再進行換擋。

                                       
Generally, when the engine speed increases to a certain extent, the engine noise will increase, and the gear must be shifted up. The shifting time is generally between 2 500-3 000 R / min (different performance engines have different starting opportunities, so you should read the operation manual first). If the novice does not learn to shift according to the sound of the engine, he can observe the tachometer under the condition of ensuring safety and feel the sound change of the engine when shifting speed. The principle of deceleration and shifting is the same, but it should be noted that when the speed is too fast, first reduce the speed to the corresponding range, and then shift.
有些駕駛員習慣于根據車速換擋，但此種做法不太適合新手，因為新手的速度感往往還沒有建立起來，建議新手還是采用根據發動機轉速換擋的方法。但大家還是應該了解不同速度階段的相應擋位。以5擋手動變速器的車輛為例，通常情況下，起步后當車速低于20 km／h時應選擇2擋，當車速為20～60 km／h時選擇3擋，當車速在60～80 km／h之間時掛入4擋，如果車速超過了80 km／h就可以掛入5擋了。
Some drivers are used to shifting according to the speed, but this method is not suitable for the novice, because the novice's sense of speed has not been established, so it is suggested that the novice should shift according to the engine speed. However, we should know the corresponding gears in different speed stages. Take the vehicle with 5-speed manual transmission as an example. Generally speaking, when the speed is lower than 20 km / h, second gear should be selected. When the speed is between 20 km / h and 60 km / h, third gear should be selected. When the speed is between 60 km / h and 80 km / h, fourth gear can be selected. If the speed exceeds 80 km / h, fifth gear can be selected.
