An internal combustion engine having a crankcase with a crankshaft and cylinders radiating from the crankcase, where the cylinders are circumferentially spaced apart. There are eccentric cams on the crankshaft which contact reciprocating pistons to move them in turn outwardly from the crankshaft. Pressurized air forced into the cylinders moves the pistons inwardly. The pressurized air and fuel are ignited in the cylinder to continue the reciprocation of the piston. Rotary valve tubes with ports supply air to the cylinders. The air is pressurized by a ram air blower. Both the rotary valve tubes and ram air blower are connected to a gear system driven by the crankshaft.
