An internal combustion engine having a power generating assembly consisting of a piston with a top step, in a similarly-shaped cylinder. This defines a reduced top compression chamber into which fuel is injected and wherein combustion takes place due to the heat of air compressed therein. Water is injected through the top wall of the normal-sized lower cylinder portion, and as the top step of the downwardly moving piston clears this wall, the water is converted into steam. An exhaust duct is connected to the intermediate portion of the cylinder and an air admission duct is connected to the lower portion of the cylinder. When the downwardly-moving piston passes the exhaust port and the air admission port, air intake and scavenging take place. The top step of the piston thus acts as a water admission valve for admitting water to be vaporized into steam into the combustion space.
