It’s a tad like likely out in a ship with a small outboard motor, you rev the outboard as well as revs keep exactly the same even though the boat gathers pace.

The combinations of gears are cautiously picked Therefore site oficial the engine can continue to be in its finest rev vary for either energy, torque (turning force) or efficiency.
