ABSTRACT:
A V-type internal combustion engine having two overhead camshafts per cylinder bank is provided with an absolutely synchronous rotational-angle adjustment between two inlet camshafts and the engine crankshaft to minimize torque fluctuations in the cam drive. One of the two camshafts actuating the inlet valves of the internal combustion engines has a device for the rotational-angle adjustment of this camshaft relative to the crankshaft and the two camshafts actuating the inlet valves are coupled to one another via a timing chain or a toothed belt which is in operative connection between an output side of the rotational-angle adjusting device and the other camshaft actuating the inlet valves.
