ABSTRACT:
An adjustable valve gear is provided for two lift-type intake valves per cylinder in an internal combustion engine which are actuated by the cams of a camshaft via rocker arms with variable support and a rocker cam. In order to make possible different lift curves for the two lift-type intake valves, each lift type intake valve is assigned a separate rocker cam. At least one of the curve joints assigned to a lift-type intake valve and establishing the connections between a cam and a rocker arm, between the rocker arm and its support and between a rocker cam and the lift-type intake valve are configured with a different shape or a rotated installation position relative to a curve joint assigned to the other lift-type intake valve.
