1. The maximum power speed (rpm) of the Glossary
refers to the maximum power speed of the engine output power corresponding to the maximum crankshaft speed. Why is there a maximum power speed? Because the engine output and speed have a direct link. In the beginning, the output power of the engine speed increases with the increase. But then reaches a maximum output, which will increase as the rotational speed of the engine decreases. Engine maximum power speed represented by r / min, meaning that revolutions per minute.
different from the maximum power speed of the engine is different. Gasoline engine maximum power speed in 5000-8000r / min, the rotational speed of the diesel engine to be a little lower, in 3000-5000r / min.
