    Abstract: According to a control strategy, a cylinder valve control device is monitored and operation of the engine is modified. The cylinder valve control device includes a driving shaft driven by the engine to drive an intermediate member which in turn drives a cam arranged to open an engine intake valve, and a driver which is operative in response to a command to vary an amount of eccentricity of the intermediate member with respect to a shaft axis of the driving shaft. During one mode of engine operation, the intermediate member is supported in a support for rotation about an axis in eccentric condition with respect to the shaft axis to accelerate and decelerate the cam with respect to rotation of the driving shaft. During another mode of engine operation, the intermediate member is in concentric condition with respect to the shaft axis to provide a synchronous motion of the cam with rotation of the driving shaft. In response to the eccentricity of the intermediate member, the engine operation is modified.

    Abstract: A driving connection between a hollow camshaft (1) and its driving shaft (5) located within it, the axes (3, 8) of these two members being parallel but laterally displaceable to vary the characteristics of rotation of the camshaft in response to constant-speed rotation of the driving shaft. The camshaft supports a slideway (11) in which moves a slider (12) which makes a rotary joint with the end of an arm (15) carried by the driving shaft. The geometry of the arm is such that the center of rotation (18) of the rotary joint lies within the outline of the periphery of the driving shaft (5) when viewed along its axis (8), thus promoting radial compactness. The essential component of the arm may be an item (15) of crescent-shaped cross-section, the concave surface (19) of the crescent registering with the surface of the driving shaft.

    Abstract: An internal combustion engine has n member of cylinders, a piston in each cylinder connected to a crankshaft (2), each piston being in phase or out of phase with the others by A.degree. or a multiple thereof (A=720/n), cams for actuating inlet and exhaust valves to each cylinder, and a cam drive mechanism (5) which rotates the cams in phased relationship with the crankshaft (2) to open the valves in sequence for a desired angle of rotation of the crankshaft. The cam drive mechanism also includes means for combining the rotational movement of the cams with a phased oscillatory movement of the camshaft (3) and cams of variable amplitude about the axis of rotation at a frequency f times the crankshaft frequency so that over the period which the valves are opened and/or their timings variable, f has the following values:f=2n when the number of cylinders n=1;f=n or n/2 when n=2;and f=n/2 when n=3 or more. The selection of the frequency of the oscillations allows all the cams to be mounted on the same camshaft.
