Webb26 mars 2016 · This process could be likened to revving a car engine. If you push the pedal down, you accelerate to full speed. If you tap the gas pedal, the engine accelerates and then slows down. If you tap it at a constant rate before it slows, you will maintain some of the momentum of the spinning motor and achieve an average (if somewhat jerky) speed. WebbWhen your engine speed (RPM) is low, it takes a lot more work to get the car up to speed. Engine temperature will rise, and cylinder temperature will rise as a result of this. Low RPMs are okay if you’re just cruising or slowing down, but when you accelerate, they give your engine a gearing disadvantage. This is where engine damage could begin.
