The engine duct and the generator duct can be formed in one body as an exhaust duct. The muffler and the generator can be laterally aligned in parallel with each other, and the engine duct and the generator duct can be located in a manner such that the directions of release of the cooling winds from the engine duct and the generator duct are parallel to each other. The exhaust duct can be located with the generator duct secured to a crankcase. An opening of the engine duct, and an opening of the generator duct can be laterally aligned with each other, and the opening of the generator duct can be positioned above the generator.

Abstract: The present invention provides an air-cooled four-stroke internal combustion engine capable of achieving a high degree of cooling. The present invention is directed to an air-cooled four-stroke internal combustion engine including a crankshaft and a fan rotor rotatably driven by the crankshaft to generate cooling air for cooling the engine. The engine comprises an oil pan disposed below the crankshaft. A space formed below the oil pan extends in the axial direction of the crankshaft along the lower surface of the oil pan and allows a cooling air to pass therethrough. An upstream portion of the lower surface is inclined upward, toward the upstream, in a vertical section taken along the axis of the crankshaft to receive the cooling air therein.
