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 ...

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.

Basically, this thing is a mashup of four-stroke and a two-stroke engine designs (here's how an engine works, by the way), that results in two power strokes in three revolutions.

Essentially, it’s a six-stroke engine that relies on a different stroke length for one of the strokes. The first three strokes are very like those in a four-stroke: intake, compression, ignition ...

A four-stroke internal combustion engine operates on the Otto cycle, a design conceived by German-born Nicolaus August Otto as early as 1861 and eventually awarded patent number 365701.

To be crystal-clear (if this is possible regarding a Garage 54 project): the Russians made a four-stroke, four-cylinder Soviet-built engine to spin in reverse. Counterclockwise. Right over left.
