摘要： An electromagnetic valve unit in an internal combustion engine is controlled by determining a difference between the output of a displacement sensor when a valve head is in an open position and the output of the displacement sensor when the valve head is in a closed position in each period of an opening and closing action of the valve head. The difference corresponds to a full displacement of the valve head between the open position and the closed position. The electromagnetic valve unit is also controlled by establishing, using the difference, a threshold for the output of the displacement sensor which corresponds to a predetermined displaced position of the valve head which is determined based on a proportion of the full displacement, and controlling energization of the valve-opening electromagnet and/or the valve-closing electromagnet depending on whether the output of the displacement sensor has reached the threshold or not upon the opening and closing action of the valve head immediately after the threshold is established.

摘要： A control apparatus for an electromagnetic actuator for driving a mechanical element by using an electromagnetic coil. The control apparatus includes a circulation circuit for circulating current to be supplied to the electromagnetic coil, a capacitor provided in the circulation circuit and to be charged by the current flowing through the circulation circuit, and a unit for, when the current supplied to the electromagnetic coil is stopped, forming a discharge path for discharging the capacitor and flowing current to an opposite direction through the electromagnetic coil. The current supplied to the electromagnetic coil is charged in the capacitor, then when the current having been supplied to the electromagnetic coil is stopped, the electric charge thus accumulated in the capacitor is discharged thereby to flow current to the opposite direction through the electromagnetic coil. Thus, the current caused by the induced electromotive force generated in the electromagnetic coil due to the stop of the supplied current can be canceled, so that the electromagnetic coil can be quickly demagnetized.

摘要： The present invention aims at expanding an operation range for allowing a compression ignition combustion operation. The present invention provides an internal combustion engine of a compression ignition type that is capable of operating with a compression ignition combustion scheme in a given operation range. The ECU of the internal combustion engine detects an operating condition of the internal combustion engine and determines, according to the detected operating condition, which mode is to be used operate the internal combustion engine, a 4-cycle compression ignition mode or a 2-cycle compression ignition mode. The ECU controls the internal compression engine to perform the compression ignition mode determined. According to the present invention, the compression ignition combustion operation is switched from 4-cycle to 2-cycle when the operating condition of the internal combustion engine is in such state that the 4-cycle compression ignition mode cannot be performed, fro example, when the exhaust temperature is low.

摘要： An electromagnetic valve controller estimates a dead time based on predetermined parameters. A dead time for the current cycle is determined based on the estimated dead time. The controller measures a dead time in the previous cycle. The controller determines a deviation between the dead time measured in the previous cycle and the dead time estimated in the previous cycle. The deviation is added to the dead time estimated in the current cycle to determine the dead time for the current cycle. The controller further determines a target de-energization timing indicating when to execute a valve timing command. The dead time determined for the current cycle is offset or subtracted from the target de-energization timing to determine an actual de-energization timing. An electromagnet of the valve is de-energized in accordance with the actual de-energization timing.

摘要： Displacement of a mechanical element is accurately detected by a simple and inexpensive structure. To provide displacement detecting device including: a mechanical element capable of being displaced; a magnet connected to the mechanical element and magnetized in displacement direction of the mechanical element; and a magnetic sensor for detecting a magnetic flux generated by the magnet and outputting a sensor output corresponding to a detected magnetic-flux value, so as to detect displacement of the mechanical element in accordance with the sensor output. In one embodiment, a Hall element is used as the magnetic sensor and the magnet longer than distance of movement of the mechanical element is used. Thus, an output having a linear relation with displacement of the mechanical element is obtained, and detection of the displacement is easily implemented. The displacement detecting device can be applied to an actuator of intake/exhaust valves of an engine. In another embodiment, a magnetic material provided between the Hall element and a spring to reduce the disturbance caused by the spring. Moreover, a transfer shaft connected to the intake/exhaust valve is made of a non-magnetic material or a material having characteristics close to the non-magnetic material to reduce the effect of leakage flux.

摘要： An electromagnetic actuator is equipped with two springs which act in opposite directions, and an armature that is connected to the springs and is supported in an unactivated state in a neutral position provided by the two springs. The armature is coupled to a mechanical element such as a valve of an engine. The actuator includes a pair of electromagnets that drive the armature between a first terminal position and a second terminal position, and a power supply device that controls the voltage supplied to the electromagnet attracting the armature to a constant voltage when the armature is driven from one of the terminal positions to the other terminal position. The voltage supplied to the electromagnets is maintained at a constant value and the larger current flows in the larger is the gap between the armature and the yoke and smaller is the counter electromotive force.
