How to match the speed and gear of driving test subject 3

First of all, we must understand the so-called relationship between gear and speed. When our manual gear starts, it always changes from the lowest gear to the highest gear, and the speed gradually increases. Each gear has a certain speed range, which means that you can only reach this level with this gear.

Why shifting depends on speed:

1. If you want to pursue acceleration performance and don't care about fuel consumption, then there is nothing wrong with shifting gears at 3500 or even 4000. But at this time, after shifting gears, before releasing the clutch, give some oil, raise the engine speed to about 2500 rpm, and then completely release the clutch, otherwise there will be a sense of frustration.

2. Considering the most economical fuel consumption and no damage to the engine, the optimal shift speed of 1.6MT Xiaoming is 2,285rpm (this can ensure that the engine speed is just kept at 1.500 rpm when shifting to the next gear).

3. According to the habit of the first gear, vehicles that drive for a long time and a short distance should drive at a low speed and a high speed for a period of time regularly to prevent carbon deposition in the engine (valve, injector). If you follow the second shift habit, this is unnecessary.
