Does High RPM Driving Damage the Car?

[LeValeria]

High RPM driving can damage the car, but the effect is relatively minor. During this process, carbon deposits can form. Reasons for carbon deposit formation: Incomplete fuel combustion, excessive fuel impurities, poor oil sealing, and exposure to high temperatures. Compared to diesel engines, gasoline engines restrict air flow during operation—simply put, the intake is always somewhat restricted, like trying to inhale while pursing your lips to whistle. The ECU detects the intake air volume based on the throttle opening, oxygen sensor, and other devices, then calculates the optimal air-fuel mixture ratio for the current operating conditions and injects the appropriate amount of fuel. Reasons for uneven combustion: Non-direct injection models require fuel injection into the intake manifold to obtain the air-fuel mixture. Low RPM or overly rich fuel conditions can lead to uneven combustion.
