Main Engines (4-Stroke)
Main Engine 4-Stroke
A four-stroke main engine completes intake, compression, power and exhaust in four piston strokes per cycle, turns far faster than a slow-speed two-stroke of comparable power, and needs a reduction gearbox to bring propeller shaft speed down to something a propeller can use.
