Does Revving in Neutral Damage the Car?

[Kent]

Revving in neutral can cause damage to the car and shorten the engine's lifespan. The extent of damage from revving in neutral depends on the circumstances: 1. When the car is in neutral, the engine is under no load. Pressing the accelerator in this state subjects some engine components to significant inertial forces, which can reduce the engine's lifespan. 2. If the accelerator is pressed in neutral immediately after starting the engine, it can accelerate engine wear. Here is additional information: 1. The throttle controls the metered fuel flow of the fuel regulator, thereby determining the thrust generated by the engine. 2. The throttle position is controlled by the driver via the throttle lever in the cockpit, which is transmitted to the carburetor or fuel regulator on the engine through control system components such as rods, rockers, torque tubes, cables, pulleys, and sector gears.
