摘要： A torque controlling apparatus for an internal combustion engine comprises an electric machinery for absorbing torque from the internal combustion engine and/or for imparting torque to the internal combustion engine; a memory unit for storing, in advance, waveform characteristics of torque deviation generated by the engine in the respective operative conditions of the engine; a detector for detecting an operative condition of the engine; and a control unit. The control unit reads out the waveform characteristics of torque deviation, from the memory unit, corresponding to the detected operative conditions of the engine detected by the detector. The control unit controls the electric machinery to generate countertorque on the basis of the read-out waveform characteristics to cancel the torque deviation.

摘要： Using a swirl type fuel injection valve, a concentrated spray area and a thin spray area are formed, the positions thereof are adjusted, and the spray is made to conform to the geometric shape of the engine and mounting position of the fuel injection valve, so as to reduce the fuel consumption and control the unburnt components in exhaust gas. The fuel injection valve is so constructed that a step is formed on the injection hole opening of the fuel injection valve, so as to provide two or more edge transition portions at the injection hole opening, resulting from the step, and the line connecting the edge transition portions forms an oblique angle relative to the wall formed by the step perpendicular to the injection hole center axis and the angled wall.

摘要： A valve structure which works easily, does not increase production cost, can reduce dispersion in a side gap by restricting eccentricity and incline of a valve body and can maintain highly accurate injection. An electromagnetic fuel injection valve is required which is easy to manufacture even in a narrow valve structure. A guide portion is provided having one end fixed to an injection valve main body for guiding the valve member. A nozzle guide body constituting a magnetic passage portion to surround a magnetic member connected and fixed to one end of the valve member by the same material is provided. Accordingly, it is possible to reduce dispersion of a side gap constituting the magnetic passage, and it is also possible to stabilize an axial motion of the valve member, whereby high injection accuracy is maintained and an inexpensive injection valve is obtained.

摘要： An electromagnetic fuel injection valve in an engine injects fuel by opening/closing a fuel flowing path with a valve element. A controller controls opening/closing of the fuel flowing path and changes magnetic force generated by a control coil driving the valve element so that the magnetic force is less during a valve open state-holding period than at an initial valve-opening time. The controller detects the voltage of a battery and applies the voltage fed from the battery to the control coil, while changing a time interval (Tc), for which current is passed through the control coil, based on the detected voltage, in order to change the magnetic force, without raising the voltage from the battery. The controller also detects increase/decrease of a pressing force on the valve element caused by fuel pressure and changes the time interval (Tc) accordingly.

摘要： In order to control a movable object such as an automobile, the differential of acceleration is derived and used as control information. In order to derive that differential, a value representing the acceleration may be differentiated, but preferably a sensor is provided which generates a direct measurement of the differential of acceleration. In one example of such a sensor, a pendulum has a coil thereon which interacts with the magnetic field of a magnet on a casing supporting the pendulum. A current is supplied to the coil such as to generate a force resisting movement of the pendulum. It is then found that the voltage across the coil corresponds to the differential of acceleration.

摘要： The target peak current value, where a current value is reduced in conformity to a drop in the voltage of a battery 18 is stored in target peak current storage unit 68. ON-signals are sent from current control circuit 56 to power transistor 50 in response to the injection command pulse coming from engine controller 58 so that current is applied to coil 20. Then, the current flowing to coil 20 is detected by the current detecting resistor 52. Comparator 62 compares this detected current and the target peak current value read from the target peak current storage unit 68 conforming to the voltage of battery 18. If agreement is found between these two values, OFF-signals are sent to power transistor 50 from current control circuit 56 in response to the switching command coming from comparator 62. Then, On/Off signals to effect holding of the coil 20 are sent from current control circuit 56 to power transistor 50. The linearity of the injection volume despite changes in battery voltage can be maintained.

摘要： A fuel-injection valve includes a fuel-injection hole, a valve element and a valve seat for opening and closing the fuel-injection hole, a force-applying member for applying force to the valve element in a direction of motion of the valve element, and a drive unit for applying force to the valve element in the direction opposite to that of the force applied by the force-applying member; wherein a secondary oscillation system, which interacts with a primary oscillation system including the valve element and the force-applying member, is added to the primary oscillation system, and the phase angle of force applied to the primary oscillation system by the secondary oscillation system is also staggered from that of force applied to the primary oscillation system, which is other than the force applied to the primary oscillation system by the secondary oscillation system, whereby the bouncing of the valve element during opening and closing of the valve is reduced, which in turn makes it possible to achieve very accurate fuel-injection control.
