Abstract
A variable valve train is provided with cylindrical cam carriers axially slidably and co-rotatably supported on camshafts. The cam carriers have thereon, respectively, plural cam lobes different in cam profile and axially adjacent to each other. Cam changeover mechanisms are provided for axially shifting the cam carriers and for changing over the cam lobes for operating on engine valves. At least one of the cam changeover mechanisms is disposed between axes of the two camshafts and on the side of an engine crankshaft relative to the axes.
