Abstract (en)
[origin: EP0340834A2] Each cylinder (1) of the internal combustion engine comprises a group of intake valves (2, 2 min ) and a group of exhaust valves (3). At least one (2, 2 min ) of said groups is formed by three circumferentially spaced out valves (2, 2 min ) operated by a single camshaft (9). Of said three valves the two lateral ones (2) are of smaller diameter with respect to the central one (2 min ) and have stems (6) which are parallel to one another and inclined with respect to that (6 min ) of the central valve (2 min ). At least one of said stems (6, 6 min ) has its axis displaced laterally with respect to the axis of rotation (10) of the camshaft (9). Means (18, 18 min ) are provided for offsetting the lateral displacement of the above axis.
