    Abstract: A valve control mechanism is disclosed which permits the engine timing to be varied as a non-linear function of axial camshaft (4) displacement. The mechanism utilises a coupling in which radially outwardly extending pegs (107) carried by a first member (80) cooperate with a variable angular pitch spline track (106) in a second member (88) positioned about said first member (80).

    Abstract: The invention concerns a hydraulic control device for turning the camshaft (10) of an internal combustion engine, the device having a linkage element (23), designed as a piston (25), which is connected to a sprocket wheel (12) on the camshaft (10) by helical gearing and is connected to the camshaft (10) by straight-tooth bevels (29, 30). Flange-fitted to the camshaft is a hydraulic unit (13) accommodating a radial piston pump (14) which supplies the hydraulic fluid necessary for displacement of the piston (25). The pressure space (78) in front of the piston is closed off by a controllable pressure-relief valve (85). A solenoid valve (39) controls the flow of hydraulic fluid from an external pump (57) to the cylinder bores (62) of the radial piston pump. Translational motion of the piston (25) causes the sprocket wheel (12) and the camshaft (10) to rotate relative to each other.

    Abstract: A device for accurately detecting an engine intake air volume based on an air volume passing through an air flowmeter in an internal combustion engine provided with a variable intake air control mechanism capable of varying the operational condition of an intake air control valve for controlling a flow of intake air into a combustion room. A throttling ratio is reduced according to the operational condition of the intake air control valve when a volumetric efficiency is lowered to calculate a throttling ratio so as to increase a throttling level. An engine intake air volume is calculated by throttling an air flowmeter passing air volume based on the obtained throttling ratio. A volumetric efficiency is calculated according to, in addition to the operational condition of the intake air control valve, an engine load and an engine revolution speed to calculate a throttling ratio based on the calculated volumetric efficiency.

    Abstract: The invention relates to a device (1) for changing the duration of opening and closing of gas-reversing valves in an internal combustion engine. It is intended to avoid disadvantageous rattling caused by very frequent abutment of the adjusting piston (9) of said device in its "late" abutment position due to a lack of hydraulic pressure during start-up, using simple means. According to the invention, it is therefore provided to position a slide (19) in a driven unit (12) of the device (1), which slide acts on radially and externally acting coupling means (24). Said coupling means (24) can be moved with partial regions of the surface (27) thereof into a recess (26) of an adjustment piston (9) of the device (1), thereby preventing the adjustment piston (9) from making further axial movement when it reaches its "late" abutment position until the device (1) has been sufficiently refilled with hydraulic medium.
