Abstract

The invention provides an air-cooled structure of a motorcycle internal combustion engine, which belongs to the technical field of internal combustion engines. It solves the problem that the temperature of the cylinder head of the existing internal combustion engine is too high at the side of the chain cavity. The air-cooled structure of the internal combustion engine of the motorcycle, the internal combustion engine includes a cylinder head, the cylinder head has a combustion chamber, a valve chamber and a chain chamber respectively, the chain chamber is flat, the air-cooled structure includes an air guide sleeve, the cylinder head has an air inlet channel, a rear The inner end of the air outlet channel and the right air outlet channel, the inner end of the air inlet channel are respectively connected with the inner end of the rear air outlet channel and the inner end of the right air outlet channel, the air guide sleeve is installed in the chain cavity, the inner end of the air guide sleeve The end communicates with the inner end of the air inlet channel. The air-cooled structure of the internal combustion engine of the motorcycle can evenly cool the surroundings of the combustion chamber, and at the same time reduce the temperature of the engine oil in the cylinder head and the chain cavity.

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 ...

Embodiment Construction

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

[0031] Such as figure 1 , figure 2 , image 3Shown, a kind of air-cooled structure of internal combustion engine of motorcycle, internal combustion engine comprises cylinder head 1, has combustion chamber 11, valve chamber 12 and chain chamber 13 respectively in cylinder head 1, and valve chamber 12 is positioned at the top of combustion chamber 11, is used for Combustion chamber 11 is for air supply and exhaust. The combustion chamber 11 is in the shape of a cylinder, 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 as a whole and is located between the combustion chamber 11 and the valve chambe...
