Abstract: A fan is suitable for an air-guiding system of an outboard motor including an internal combustion engine and a covering hood bounding an engine interior space. The engine drives the fan, which is connected to an upright shaft journal projecting beyond an upper side of a housing of the engine. The covering hood has air flow openings, and the fan influences the air flows in the covering hood interior space. A flywheel, fixedly attached to the upright shaft journal, carries a fan wheel of the fan. The fan wheel is set in place from above, and the flywheel carries the fan wheel for conjoint rotation. Airflows enter the interior space via an inlet opening and a first conducting device, and the airflows, under the action of the fan, act upon at least parts of surfaces of the internal combustion engine and the auxiliary units to cool the internal combustion engine.

Abstract: An air cooling system for an unmanned aerial vehicle including a propeller (14) driven by an engine (12) has at least one cooling air duct (22) to direct cooling air to cool a vehicle component e.g. a cylinder head. The duct has at least one air inlet and at least one air outlet. Operation of the propeller causes a pressure differential between the air outlet (24,124) and the air inlet (23,123) which draws air through said cooling air duct (22). A cowling (16) can cover at least part of the engine, and can form a plenum and have the supply of cooling air through a front face aperture (164) or side walls (17) of the engine cowl (16).

Abstract: Self-cooled engine including a cylinder, a cylinder head and 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. The force of 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. The high intensity compression swirl (HICS) created at the end of the compression stroke to ensure that the fuel combustion is efficient and instantaneous release of maximum energy.
