    摘要： For example, while the state of combustion of an internal combustion engine is detected from a cylinder pressure at the top dead center of the cylinders, if a decision has been made that the detected combustion state is an irregular combustion state, on the basis of a result of comparison between a torque waveform corresponding to the irregular combustion state and a torque waveform under normal combustion state, this torque control apparatus for internal combustion engines according to this invention puts into operation a torque correcting device, such as a motor-generator, mounted fixedly to the internal combustion engine, thereby making the former torque waveform approach the latter torque waveform. Therefore, even when an irregular combustion occurs in the internal combustion engine, the torque waveform is substantially free from irregularity, so that vibration and an abnormal noise can be prevented.

    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： 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 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.
