Does Revving in Neutral Damage the Car?
1 Answers
Revving the engine while in neutral can indeed cause damage to the car. Here are the relevant explanations: 1. Although the gear is in neutral, the engine's power drives the input shaft of the transmission through the clutch, keeping the transmission in a working and rotating state. When the throttle is pressed in this situation, except for the output shaft and the synchronizers of each gear not rotating, the input shaft, intermediate shaft, and the constant-mesh gears on the shaft will all rotate at varying speeds according to the engine's RPM. 2. Prolonged revving in neutral or long-distance coasting in neutral can be harmful to the transmission. It can easily lead to wear, burning, or pitting of the input shaft bearings, synchronizer gears, and synchronizers, as well as cause abnormal noises in the transmission. Therefore, drivers should avoid revving the engine in neutral during normal operation.
