Each HD includes an elliptical wave generator (WG), a flexspline (FS) deformable by the WG, and a circular spline (CS) for engaging the FS. A dynamic spline (DS) connects the first and second FSs. The first HD is an input HD driven by an engine crankshaft via a sprocket wheel connected to the input CS. The second HD is an output HD driving an engine camshaft. The DS is meshed with both the input FS and the output FS. The phase relationship between the crankshaft and the camshaft may be changed by changing the angular relationship between the first and second WGs. Such change is effected by holding the first WG stationary and varying the angular position of the second WG via an electric motor.

The height of the rotor is less than the height of the stator, providing space for a vaned brake rotor alongside the camshaft rotor. The brake rotor is free to rotate independently of the camshaft rotor. The volume of each advance and retard chamber is a function of the rotational position of both the camshaft rotor and the brake rotor, and the volume of each chamber is constant. Rotation of the brake rotor in one direction causes rotation of the camshaft rotor in the opposite direction. The brake rotor is connected to a controllable brake mechanism. By sensing of the camshaft rotor position and feedback control of the braking mechanism, the camshaft rotor may be maintained at any position.

The camshaft adjuster is not required to be mounted inside the cylinder head (33), but can be mounted as a separate unit on the cylinder head (33) of the internal combustion engine independent of the lubricating oil circuit. This expands, in particular, the range of possibilities for use of the camshaft adjuster (13) with a belt drive.

Abstract: Extremely high injection pressures are achieved in a common rail fuel injection system via a movable intensifier positioned in each fuel injector. The fuel injectors are individually controlled via a single electrical actuator that moves between positions that connect an intensifier control cavity either to the high pressure common rail or a low pressure reservoir. Leakage is avoided between injection events by maintaining opposing hydraulic surfaces of the intensifier and needle valve exposed to fluid pressure in the high pressure rail. This avoids pressure differentials and leakage associated with guide surfaces separating high and low pressure areas.

Abstract: A preset waiting period is previously set on the basis of a signal in correspondence to a detection of a start point of a detection of a no-tooth portion of a signal rotor. In the case of a control for injecting a fuel after the preset waiting period has elapsed, an output of a signal indicating a start point of an actual detection of the no-tooth portion by a waveform shaping portion is delayed due to the existence of the no-tooth portion. A control computer corrects the preset waiting period to be shorter by an amount corresponding the delay. Accordingly, an accuracy of a fuel injection start timing control is improved.

Abstract: A method for controlling a piezoelectric actuator of a fuel injector for controlling the quantity of fuel injected into the cylinders of an internal combustion engine controls the voltage across the injector in accordance with a voltage/charge vs. time profile in which the injector is driven at high current up to a level required to start injection, and then at lower current, resulting in a lower voltage/charge vs. time gradient, until the point where full charge is achieved. This results in a reduced variation in minimum delivery pulse and a reduction in the slope of the gain curve, as compared with conventional arrangements in which the voltage/charge vs. time gradient is constant. Alternatively, the injector may be driven at high current up to the charge level required to switch to hydraulic lift amplification. Any point of current change between these extremes may also be used with good effect.

Abstract: An internal combustion engine is provided. Facing pistons eliminate a cylinder head, thereby reducing heat losses through a cylinder head. Facing pistons also halve the stroke that would be required for one piston to provide the same compression ratio, and the engine can thus be run at higher revolutions per minute and produce more power. An internal sleeve valve is provided for space and other considerations. A combustion chamber size-varying mechanism allows for adjustment of the minimum size of an internal volume to increase efficiency at partial-power operation. Variable intake valve operation is used to control engine power.

Abstract: A high-pressure fuel pump (10) used in a fuel system includes an electric motor (14) having a drive shaft (16) to which is attached a pumping element (18). A fuel inlet passage allows low-pressure fuel to be drawn into the pump, and a fuel outlet passage (24) allows high-pressure fuel to be pumped to an internal combustion engine (E). A check valve assembly (30) is installed in the outlet passage and includes a check valve (36) which, when the pump is off, blocks an inlet (38) into the outlet passage to prevent fuel flow through the passage and into the pump resulting in a decrease in pressure in the fuel system. When the pump is operating, the check valve is forced away from the inlet to open the valve and allow fuel to freely flow through the passage. The fuel flows both around and through the check valve as it flows through the outlet passage.
