強制空冷頭上弁エンジン。[Claims for Utility Model Registration] A fan case 1 is attached to the front of the engine body of a forced air-cooled overhead valve engine E, and within the fan case 1, an air blowing chamber 2 is provided in front of the crankcase, and a cylinder 3 and a cylinder head 4 are provided. A wind guide chamber 5 is provided on the front side, a cooling fan 6 is arranged in the wind blowing chamber 2, and the cooling air generated by the cooling fan 6 is sent from the wind blowing chamber 2 to the cylinder 3 and the cylinder head 4 via the wind guide chamber 5. In a forced air-cooled overhead valve engine configured to 1, an exhaust pipe cooling chamber 12 is formed on the outer periphery of the cooling fan 6 from the closing point 8 of the partition plate 7 to the closing point 10 of the air blowing chamber 2 along the fan rotation direction, and the exhaust pipe 14 is guided. This forced air-cooled overhead valve engine is characterized in that the air is led out of the fan case 1 from the air chamber 5 through the exhaust pipe cooling chamber 12, and an exhaust port 40 is provided in a downstream portion of the exhaust pipe cooling chamber 12.
