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. WebbSlow Speed engines are engines in the range of 50 – 300 rpm at rated power. These are mostly two stroke, crosshead engines with between 4 to 12 cylinders in line and …
