What are the effects of a new car's engine speed exceeding 5000 RPM?

[Molly]

There is no impact. During factory production, engines undergo high-load testing. At 5000 RPM, the average piston speed is significantly lower than 80 feet per second, which falls within the safe speed range. Below is relevant information about engine speed: 1. Overview: The engine speed determines the number of work cycles per unit time or the effective power output of the engine, meaning the engine's effective power varies with different speeds. Therefore, when specifying the engine's effective power, the corresponding speed must also be indicated. 2. Speed measurement: Typically, a speed sensor is used, corresponding to the signal teeth on the flywheel, to measure the engine's speed.
