Problems solved by technology

[0002] At present, customers have higher and higher requirements for the power performance of four-stroke motorcycle engines. The improvement of power performance will lead to high thermal load of the engine, especially for the durability of thermal components, and the thermal deformation of the valve seat of the cylinder head is large. Lead to poor valve sealing and rapid valve seat wear, thereby reducing engine life

Abstract

The invention discloses a motorcycle engine cylinder head with a valve seat cooling oil passage. The cylinder head is provided with an exhaust valve seat, a spark plug hole, a camshaft mounting hole and a chain chamber, wherein the exhaust valve seat and the cylinder head are connected in an interference fit. The cylinder head is characterized in that an oil passage is arranged on the cylinder head, an oil inlet of the oil passage is close to the position of the exhaust valve seat 3, the oil passage passes the vicinity of a spark plug, the oil passage is in communication with the camshaft mounting hole, the oil passage sequentially cools the exhaust valve seat, the spark plug and a camshaft through making the oil pass through the oil passage, and the oil is made to return to the chain chamber and then return to a crank case. The cylinder head is advantaged in that through arranging the oil passage near the cylinder head exhaust valve seat, the oil passage passes through the vicinity ofthe spark plug, the oil cools the exhaust valve seat and cools the spark plug, the heat load of the cylinder head and the temperature of a spark plug gasket are reduced, valve seat heat deformation is reduced, valve sealing is improved, lubricating and cooling the camshaft are further achieved, and the overall life of an engine is improved.

Description

technical field [0001] The invention relates to the technical field of motorcycle engine cylinder head cooling, in particular to a novel motorcycle engine cylinder head with valve seat cooling oil channels. Background technique [0002] At present, customers have higher and higher requirements for the power performance of four-stroke motorcycle engines. The improvement of power performance will lead to high thermal load of the engine, especially for the durability of thermal components, and the thermal deformation of the valve seat of the cylinder head is large. This leads to poor valve sealing and rapid wear of the valve seat, which reduces the life of the engine. In order to solve these problems, a new type of cylinder head needs to be designed. Contents of the invention [0003] The present invention is to overcome the above-mentioned problems existing in the prior art, and provides a motorcycle engine cylinder head with a valve seat cooling oil passage. The present in...
