Abstract:
1. An internal-combustion engine comprising an engine block defining a plurality of cylinders, and engine shaft, and a cylinder head, as well as a pair of shafts mounted rotating in the cylinder head and controlled in rotation by the engine shaft via transmission means, wherein one of said shafts mounted rotating in the cylinder head is a camshaft comprising cams for control of intake valves of the engine and cams for control of exhaust valves of the engine, wherein the cams controlling the intake valves control said intake valves by means of an electronically controlled hydraulic device for variable actuation of the intake valves, wherein the cams controlling the exhaust valves control said exhaust valves mechanically, and wherein the second shaft of said shafts mounted rotating in the cylinder head is without cams and has one end coming out of the head and constituting a power take-off, and wherein all the components of the electronically controlled hydraulic device for variable actuation of the intake valves are carried by a structure fixed on the cylinder head and having a bottom surface for resting on the cylinder head, which coincides with the plane passing through the axes of the two shafts mounted rotating in the cylinder head.
