Self-cooled engine including a cylinder and cylinder head with a turbo-piston which freely reciprocates inside the cylinder. The cylinder head has a valve that achieves circumferential suction of air-fuel mixture into the cylinder. The valve mechanism is closed and opened by cylindrical cam by means of cam shaft. Circumferential suction of air-fuel mixture enables the cylinder to cool itself and to burn the fuel at the energy center effectively. An incoming stream of air-fuel mixture rotates the impeller on the piston which acts as a fan to cool the cylinder walls. The impeller blades deflect the flame from reaching the cylinder walls and acts as a thermal barrier between the energy center and cylinder walls. A high intensity compression swirl (HICS) is created at the end of the compression stroke to ensure that the fuel combustion is efficient and instantaneous release of maximum energy.
