What Does Synchronizer Gear Shifting Mean?

[StAmy]

It refers to the gear shifting technique for manual transmission vehicles. The details are as follows: 1. Synchronizer: Currently produced vehicles are equipped with synchronizers in their transmissions. The presence of a synchronizer effectively prevents gear collisions and significantly simplifies the gear shifting operation. Nowadays, whether upshifting or downshifting, it is no longer necessary to use the traditional double-clutch method; instead, the single-clutch method is commonly used (this should not be interpreted as a denial of the rationality of the double-clutch method), which largely resolves the difficulties encountered during gear shifting. 2. Correct Operation Method of Clutch Pressing and Throttle Releasing: Pressing the clutch and releasing the throttle should be done simultaneously (or almost simultaneously). Even if there is a sequence, the clutch should be pressed first, followed by releasing the throttle. Note that the throttle release should not be too delayed; otherwise, since pressing the clutch is equivalent to unloading the engine's load, and the throttle is not released in time, the engine speed will rapidly increase.
