What does 'lifting off the throttle' mean?

[DeKinsley]

'Lifting off the throttle' means releasing or reducing the throttle, which applies to both automatic and manual transmission vehicles. Since manual transmission cars require lifting off the throttle during gear shifts, it is incorrect to always keep the throttle pressed in automatic cars; instead, one should frequently lift off the throttle and coast. Throttle control is an important aspect of driving technique. Below is some related information about the throttle: 1. Throttle function: The throttle controls engine power. In piston aircraft engines, the throttle adjusts the carburetor's throttle valve opening to regulate cylinder filling, thereby determining the engine's output power. In gas turbine engines, the throttle controls the fuel regulator, determining the engine's thrust. 2. Precautions when pressing the throttle: Generally, when starting, the clutch and throttle can be pressed simultaneously, but during gear shifts, they should not be pressed together, as this can cause unstable driving.
