I like the old 6-stroke engines better: - Dyer/Crower engine = 5th stroke compresses air only, then inject cold water into the overheated cylinder and has another power stroke on 6th (from the generated steam) - Ilmor/Schmitz = the exhaust stroke from two normal 4-stroke cylinders power the down-stroke of a 3rd larger cylinder, alternatively, then evacuates the gas on 6th up-stroke.
