Example Embodiment

[0030] The following are specific embodiments of the present invention combined with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0031] Such as figure 1 , figure 2 , image 3 As shown, an air-cooled structure of a motorcycle internal combustion engine includes a cylinder head 1. The cylinder head 1 has a combustion chamber 11, a valve chamber 12, and a chain chamber 13, respectively. The valve chamber 12 is located above the combustion chamber 11 and is used for matching The combustion chamber 11 supplies air and exhaust gas. The combustion chamber 11 is cylindrical, and a large amount of heat generated by it is transferred to the periphery of the combustion chamber 11 and the periphery of the valve chamber 12. The chain chamber 13 is flat and located in the combustion chamber 11 and the valve chamber 12. On one side, the cross section of the cylinder head 1 is rou...

Abstract

The invention provides an air-cooling structure of an internal combustion engine of a motorcycle, and belongs to the technical field of internal combustion engines. The invention solves the problem that the temperature of a cylinder head at the chain chamber side of a present internal combustion engine is over high. According to the air-cooling structure of an internal combustion engine of a motorcycle, the internal combustion engine comprises a cylinder head, the cylinder head has a combustion chamber, a valve chamber and a chain chamber, and the chain chamber is flat. The air cooling structure comprises a wind guide sleeve. The cylinder head has an air inlet channel, a rear air outlet channel and a right air outlet channel, the internal end of the air inlet channel is respectively in communication with the internal end of the rear air outlet channel and the internal end of the right air outlet channel, the wind guide sleeve is inserted in the chain chamber, and the internal end of the wind guide sleeve is in communication with the internal end of the air inlet channel. The air-cooling structure of an internal combustion engine of a motorcycle can uniformly cool the surrounding of a combustion chamber, and reduce temperatures of the cylinder head and machine oil in a chain chamber.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engines, and relates to an air cooling structure of a motorcycle internal combustion engine. Background technique [0002] There is an exhaust channel on the front side of the conventional cylinder head, and an air intake channel on the rear side, while the air channel on the top of the combustion chamber intakes air at the front side and outputs air at the right and rear sides, and the chain chamber is located on the left side of the cylinder block , due to the requirements of arranging the chain and sealing the oil, the outlet cannot be set. The combustion chamber is equipped with cooling fins on the front, right and rear sides, which are in direct contact with the outside world. However, the combustion chamber has no cooling fins on the side of the chain cavity, and is in contact with the oil mist. Because the temperature of the engine oil is relatively high, this side The ability ...
