Four strokes — down, up, down, up — complete the cycle that creates the power to drive the engine. This process is aptly called the four-stroke power cycle .

Compared to the four-stroke engine that produces one power stroke per two revolutions at 3,000 rpm, the four-stroke has 1,500 power strokes while the six-stroke would have 2,000.

A four-stroke engine uses four motions of a piston to complete one cycle of combustion. The first stroke of a cycle is the intake. The piston moves down to BDC, making space in the cylinder for ...

Like countless other 19th-century inventors, entrepreneurs, and tinkerers, British engineer James Atkinson sought ways to improve on the Otto four-stroke combustion engine, first produced in 1876.
