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 installation hole, and a chain room. The exhaust valve seat shown It is connected with the cylinder head with an interference fit, and it is characterized in that an oil passage is set on the cylinder head, the oil inlet of the oil passage is close to the position of the exhaust valve seat 3, the oil passage passes near the spark plug, and the oil passage and the cam The shaft mounting holes communicate with each other, and the oil passage cools the exhaust valve seat, the spark plug and the camshaft sequentially through the oil passage, returns the oil to the chain chamber, and then returns to the crankcase. In the present invention, an oil passage is arranged near the exhaust valve seat of the cylinder head, and the oil passage passes near the spark plug, so that the engine oil not only cools the exhaust valve seat, but also cools the spark plug, thereby reducing the heat load of the cylinder head and the temperature of the spark plug gasket, and reducing the temperature of the valve. Seat thermal deformation, improve the sealing of the valve, while lubricating and cooling the camshaft, improve the overall life of the engine.

Description

Technical field [0001] The present invention relates to a cylinder head cooling motorcycle engine technical field, and particularly relates to a novel motorcycle engine cylinder head having a valve seat cooling gallery. Background technique [0002] Currently, customers dynamic performance four-stroke motorcycle engine is increasingly high demand, improve dynamic performance of the engine results in a high thermal load, especially for heat durability member can require a higher heat distortion larger cylinder head valve seat, resulting in poor sealing valve, valve seat wear quickly, thereby reducing engine life. To solve these problems, we need to design a new cylinder head. Inventive content [0003] The present invention is to overcome the above problems in the prior art, there is provided a cylinder head for a motorcycle engine having a valve seat cooling gallery, the present invention utilizes the limited space of the cylinder head, the exhaust valve seat and to achieve cool...
