Can the throttle be released quickly?
2 Answers
Throttle cannot be released quickly. Here are the relevant explanations: 1. Reason: When the throttle is completely released, the fuel supply reaches its minimum limit. While driving, the throttle can only be fully released when the transmission is shifted back to neutral. At this time, the vehicle moves forward by inertia. Otherwise, driving at idle speed in a high gear will not only stall the vehicle but also cause the vehicle to stop suddenly, damaging the transmission and potentially leading to rear-end collisions on the road. 2. Throttle: The throttle, also known as the "air throttle" or "throttle valve," refers to the control device that regulates the engine power (thrust). In piston aircraft engines, the throttle controls the opening of the carburetor's throttle valve to regulate the cylinder's filling volume, thereby determining the engine's output power. In gas turbine engines, the throttle controls the metered fuel flow of the fuel regulator, thus determining the thrust produced by the engine.
When I was taking my driver's license test, the instructor repeatedly emphasized not to suddenly release the accelerator pedal as if electrocuted! Especially with a manual transmission car, during my initial practice for Subject 3, I once abruptly let go of the accelerator, causing the car to lurch forward and then jerk back violently, even knocking over the water bottles of the passengers in the back. The instructor shouted loudly: the accelerator pedal should be lifted off gradually, unless you need to brake suddenly and press the clutch. This control ability directly determines ride comfort, and suddenly releasing the accelerator can cause fuel control disorder, leading to a sudden spike in instantaneous fuel consumption and damaging the engine. Remember, maintaining steady control is most important. When cruising on the highway and encountering a slowing car ahead, I always start gently lifting the accelerator 200 meters in advance to slow down.
