摘要

1. Four-stroke internal combustion engine which comprises either three inlet valves or three outlet valves or three inlet and three outlet valves per cylinder, with a first cam shaft for the inlet valves and a second cam shaft for the outlet valves, the tams of said cam shafts acting upon the valves via cup-shaped tappets, characterized in that at least the longitudinal middle axis (19) of the tappet (8b) cooperating with the intermediate valve (4) of the three inlet and/or outlet valves (3, 4, 5) penetrates the plane (22) placed through the axis of rotation (21) of the respective cam shaft (14) at right angle to said longitudinal middle axis (19) at a distance (a) from the axis of rotation (21) of the cam shaft (14).
