OPERATING VALVE GEAR FOR INTERNAL COMBUSTION ENGINE

摘要

PURPOSE: To provide a valve gear assembly capable of adjusting a valve stroke process so as to be various and different from each other. CONSTITUTION: This internal combustion engine is provided with at least two intake-stroke valves for each cylinder. The stroke processes of the stroke valves can be adjusted so as to be different from each other. This adjustment is made by an eccentric shaft 10. The eccentric shaft moves the supporting point of a transfer member between respective cams 5a and stroke valves 4. Both eccentric bodies 10a, 10a' attached onto the cylinder are of a different geometry from each other. The transfer member are supported by the eccentric bodies 10a, 10a' and formed by a locker lever operated by the cam 5a. The locker lever works onto a swing lever. Other transfer member includes a gate track 8a.
