What are the effects of car engine speed exceeding 3000 rpm?

[McAshlyn]

Car engine speed exceeding 3000 rpm will significantly reduce the lifespan of the vehicle's engine. Here is a relevant introduction about high and low engine speeds: 1. High speed: When the engine operates at high speeds, it can achieve full combustion, reducing carbon deposits. However, if the vehicle outputs excessive torque at 3500-4000 rpm, prolonged driving or gear shifting at this speed range will subject various components (engine, transmission, tires, etc.) to excessive torque, leading to reduced lifespan. 2. Low speed: Since the engine often needs to operate at low speeds, statistics show that about 30% of urban vehicle fuel consumption occurs in the low-speed phase. Therefore, reducing fuel consumption during low-speed operation is crucial, which is also the requirement for low-speed control.
