Problems solved by technology

At the same time, the opening of the valve is realized by the impact of the rocker arm. The impact of the rocker arm on the valve will increase the noise and vibration of the engine. The repeated impact of the rocker arm on the valve will easily change the valve clearance, affect the engine power, and increase the engine power. engine noise

Embodiment Construction

[0016] see figure 1 , This embodiment is an embodiment in which the valve train is installed on the cylinder where the junction between the cylinder head 18 and the cylinder block 24 is located at the intake and exhaust passages. The rod portion of the valve 3 is reasonably clearance-fitted in the valve sleeve 5 that is press-fitted on the cylinder head 18, and the valve cone angle and the circumference of the lower end of the valve 3 head are fitted in the intake and exhaust ports of the combustion chamber 1 by interference. The working slope of the valve seat 2 of the mouth cooperates to form a seal, and the working slope of the valve seat 2 that cooperates with the valve is located at the intake and exhaust passages 4,19 one side. The upper part of the stem of the valve 3 is provided with a step and a ring groove, the spring bushing 6 is set on the stem of the valve 3, and is axially positioned on the stem of the valve 3 through the step and the retaining spring 9, and the ...

Abstract

The invention relates to a lifting gas distributor of motorcycle engine, which comprises: a valve, a valve base, and a cam axle, wherein said valve is axially mounted with spring liner base; the spring cover base is connected to the cylinder cover; the spring is sheathed on the spring liner base to be limited by spring liner base and spring cover base; the end of valve via nut is locked on the device for lifting valve whose upper and lower ends of lifting post are space matched in the hole of cylinder cover, while its upper end supports the spring in the hole of cylinder cover, and its lower end contacts the cam axle. The invention uses lifting method to turn on the valve to increase the open degree of valve, to improve the efficiency of engine and reduce the noise.

Description

technical field [0001] The invention relates to a gas distribution mechanism of an engine, in particular to a lifting type gas distribution mechanism of a motorcycle engine. Background technique [0002] At present, the valve mechanism of the engine of a traditional motorcycle generally transmits the motion of the camshaft to the valve through the rocker arm to open the valve. Since the valve is opened to the combustion chamber, the valve cone angle of the valve is arranged on the back of the valve head. The rocker arm is a double-arm lever supported in the middle. When working, one end of it is pushed by the cam or the push rod and the other end hits the down-pressed valve, so that the valve extends into the combustion chamber to open the valve, and then the valve is closed by the elastic force of the valve spring. . However, when the engine is working, the valve cannot collide with the piston, so the amount of the valve protruding into the combustion chamber—that is, the ...
