    摘要: A system and method are described for reducing engine vibration during cylinder deactivation in selected operating conditions. The method utilizes open valve deactivation to better match the cylinder pressure of deactivated cylinders to combusting cylinders. This mode is utilized, along with cylinder closed valve cylinder deactivation, to improve overall fuel economy, while at the same time reducing vibration felt by the vehicle driver.

    摘要: A starting device for an internal combustion engine is capable of increasing starting torque as well as supplying air to a cylinder that is on the expansion stroke without separately providing a means for supplying high-pressure air. Communication control valves control the states of communication between cylinders of the engine. A crank angle detector detects the crank angle of a crankshaft of the engine. A compression/expansion identification part identifies the compression stroke or the expansion stroke of each cylinder. Fuel is injected into a cylinder on the expansion stroke and ignited therein, and the expansion stroke cylinder is placed in communication with a cylinder on the exhaust stroke by a communication state control part for a prescribed time after the ignition thereof, after which the expansion stroke cylinder is further placed in communication with a cylinder on the compression stroke for a prescribed time.

    摘要: A method to compute, store, and inject adaptive valve timing corrections in a camless valvetrain architecture where a measurable (based on the resolution of the measuring methodology) error exists between the requested and delivered valve timing. This method is based on a measurement of the delivered valve timing, such as from a direct position sensor, (hall effect, LVDT, optical, etc.) or inferred position sensing based on valve actuator current (electronic actuation) or pressure (hydraulic actuation) feedback. This measured delivered valve timing information is used to compute offsets which, when applied to the desired timing, provide more accurate correlation between the delivered timing and the desired timing.

    摘要: A control method with variable feedback gain for energization of an electro-magnetically driven intake/exhaust valve of an internal combustion engine increases opening and closing speeds of the intake/exhaust valve driven with electromagnets having small capacity and improves the control performance in bringing the final speed of the opening and closing action of the valve close to zero. According to the variable feedback gain energization control method, a target moving speed of the armature relative to the electromagnets is determined dependent upon a spacing distance of the armature from the electromagnet; at least a part of energization of the electro-magnetically driven valve is controlled through feedforward control so as to make an actual moving speed of the armature relative to the electromagnets in conformity with the target moving speed while at least the other part of the energization is controlled through feedback control based upon a deviation of the actual moving speed from the target moving speed. And a gain of the feedback control is changed based upon a relation between the actual moving speed and the target moving speed. The energization control is modified through learning modification based upon the deviation between the actual and target moving speeds and the actual value of the final speed of opening and closing the valve.

    摘要: A control method for modulating the torque in an internal combustion engine with mechanical power transmission and with pneumatically, hydraulically or electromagnetically controllable valves that are open and closed based on signals from a control system, by which method a torque that is requested in an operative situation at a certain moment is provided by a selection of the frequency with which power strokes are performed by controlling the number of power strokes in relation to the number of idle strokes. The power strokes take part in 2-stroke cycles or 4-stroke cycles, and one or more 2-stroke cycles are alternated with or more 4-stroke cycles.

    摘要: An intake valve control system for an internal combustion engine includes a first valve control mechanism for varying an actual operation angle of an intake valve, a second valve control mechanism for varying an actual maximum lift phase of the intake valve and a control unit that operates the first and second valve control mechanisms to adjust an intake air amount by controlling the operation angle predominantly in a low-intake range and controlling the maximum lift phase predominantly in a high-intake range. The control unit is configured to calculate a target operation angle and a target maximum lift phase according to engine operating conditions so that the actual operation angle and maximum lift phase are controlled to the target operation angle and maximum lift phase, respectively, and correct the target operation angle in a transient operating state where the actual maximum lift phase deviates from the target maximum lift phase.
