What is the difference between lightly pressing the accelerator and heavily pressing the accelerator?
2 Answers
The main difference between lightly pressing the accelerator and heavily pressing the accelerator lies in the speed at which the engine RPM increases. Here are the specific details: Lightly pressing the accelerator: Lightly pressing the accelerator allows the car to drive at a low RPM, gradually increasing speed through inertia and controlled throttle input. The most obvious manifestation of this is the mismatch between the car's speed and the engine's RPM, which not only causes severe engine vibration but also leads to the engine operating under excessive load. This has a significant negative impact on the engine and can result in severe carbon buildup. Heavily pressing the accelerator: Heavily pressing the accelerator increases the engine RPM, and correspondingly, the engine's air intake also increases, improving the combustion efficiency of gasoline. Naturally, this provides stronger power but results in higher fuel consumption.
Lightly pressing the accelerator is mainly for smooth driving and fuel efficiency, keeping the RPM at a low level, allowing the car to accelerate gradually. It is suitable for daily commuting and urban roads, reducing fuel consumption. Heavily pressing the accelerator makes the engine respond quickly, with RPM soaring and power surging, suitable for overtaking or quick starts, but fuel consumption increases significantly. After driving for a long time, I found that frequent heavy pressing can aggravate engine wear, leading to higher maintenance costs in the long run. It is recommended to choose the pressing method based on road conditions under the premise of safety.
