Abstract: A reference angle detecting device includes a control shaft (60) that is connected to a controlled object (e.g., to a variable valve actuation mechanism of an engine E) and an electric motor (73) that causes the control shaft (60) to rotate via a worm gear mechanism (72), a stopper (80) disposed on a motion track of a worm wheel (74), an angle sensor (94) that can detect a rotation angle of the control shaft (60), and a controller (90). The stopper (80) includes a spring member (for example, torsion coil spring (84)) which is elastically deformable in an operation direction of the worm wheel (74). The controller (90) drives the electric motor (73) to operate so that the worm wheel (74) may face the stopper (80), and stores the rotation angle at a time point when a change rate É of the rotation angle ¸ detected by the angle sensor (94) changes to a value less than a predetermined threshold É1 as a reference angle ¸ 0 . With this, the reference angle can be detected with high accuracy for control of an angle of the control shaft.

Abstract: A system for variable actuation of an engine valve of an internal-combustion engine, comprises a master piston (16) and a slave piston (21), which drives the engine valve (7) and is hydraulically driven by said master piston (16) by means of a volume of pressurized fluid (C). The system further comprises an electrically operated control valve (24), which controls a communication of the volume of pressurized fluid (C) with a lower pressure environment (23). A device (D) for dampening pressure oscillations is connected to the volume of pressurized fluid (C) and comprises an additional volume adapted for receiving fluid from the volume of pressurized fluid (C) only when, following upon oscillations of the pressure in the volume of pressurized fluid (C), the pressure exceeds a maximum threshold value, which is higher than a mean pressure value that is set up in the volume of pressurized fluid (C).

Abstract: A control unit for an internal combustion engine is configured for suppressing knocking phenomenon with reduction of overlap, while maintaining an opening timing of an exhaust valve at the time of low-rotation, high-load state. A valve opening/closing timing control apparatus includes a phase adjustment mechanism configured to vary a relative rotational phase between a driving side rotary body rotatable in synchronism with a crankshaft of the internal combustion engine and a driven side rotary body rotatable together with an exhaust cam shaft. After an opening timing of the exhaust valve, an advancing operation is effected for displacing the relative rotational phase in the advancing direction relative to the opening timing.

Abstract: An internal combustion engine (1) includes a first bank (A) and a second bank (B). The first bank (A) includes a continuously variable valve apparatus (600A) that continuously changes a valve characteristic of an intake valve. The second bank (B) includes a multi-stage variable valve apparatus (600B) that changes the valve characteristic in multiple stages. An engine control apparatus (100) adjusts the intake air amount of the first bank (A) by adjusting the valve characteristic that is changed by the continuously variable valve apparatus (600A), based on the intake air amount of the second bank (B).

The valve gear includes a spring member (66) for return which biases the first rocker arm (52), and a second rocker arm (54) which presses an intake valve or an exhaust valve (9). The valve gear includes a first pin hole (63) of the first rocker arm (52), a second pin hole and a third pin hole (82) of the second rocker arm (54), a first switch pin (55), a second switch pin, a third switch pin (57), and a switching mechanism (3) which witches between the connected state and non-connected state of the switch pins. The second rocker arm (54) includes a stopper (78) against which the first rocker arm (52) abuts. When the first rocker arm (52) abuts against the stopper (78), all the pin holes are located on the same axis. It is possible to provide the valve gear in which the switch pins readily and reliably move when switching between a form in which the two types of rocker arms are integrated and a form in which the rocker arms are separated.
