Patent ID: 8042505

Claim:
A combustion engine having a valvetrain for actuating a first intake valve and a second intake valve, comprising: a first driving member, which is arranged in a cylinder head portion of the combustion engine, and which is rotatable about a first rotation axis for actuating the first and second intake valves; a second driving member for driving the first driving member, wherein the second driving member is rotatable about a second rotation axis; a connecting rod with a first joint and a second joint; and a guiding member for guiding the connecting rod, the guiding member being pivotable around a guiding member axis; and a valve spring, wherein: the first joint of the connecting rod is joined to the first driving member; and the second joint of the connecting rod is joined to the guiding member; the position of the first rotation axis is pivotable about the second rotation axis; and a phase relation between a rotational angle of the first driving member and an engine cycle is adjustable by the pivoting of the position of the first rotation axis.
