Abstract (en)

[origin: EP0845582A1] Each cylinder of the engine is fitted with at least two inlet valves and with at least two exhaust valves, driven by two parallel cams (9,10) which drive cam followers mounted between hydraulic supports and the ends of the valve stems. Alternate cylinders are in a V-formation with each cylinder having the cam axes between the axes of the valves and the axes of the hydraulic supports. The valve guides and hydraulic supports are on alternate sides of the cam axes on alternate cylinders. The valve guides and hydraulic supports are parallel to each other. The hydraulic supports are connected to the lubrication circuit.
