Inventor: TAKEMURA SHINICHI
IPC: F01L13/00
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To provide a variable valve system for internal combustion engines, capable of improving the stability of engine. SOLUTION: When a cam shaft 3 is rotated, a rocker arm 14 is oscillated by an eccentric cam 4, an oscillating cam 8 connected to the rocker arm 14 through a link member 17 is oscillated, and a valve lifter 11 is moved vertically by means of a cam face 8b of the oscillating cam 8. The cam face 8b of the oscillating cam 8 is formed into a shape by which the cam face can be brought into contact with the valve lifter 11 at an about fixed position up to a maximum valve lift position after a specified amount of valve lift of an intake valve 10 is reached. Thus, dispersion in the amount of valve lift, which is caused by the shift of the contact-point of the oscillating cam 8 with the valve lifter 11 can be reduced, and dispersion in the intake air quantity per a cylinder can also be reduced.
