摘要： An apparatus induces vibrations in a generator for effectively reducing vibrations of a vehicle engine and the vehicle body due to irregular combustion of the engine. The load torque of a generator fixed to the engine is changed to generate an angle moment on the body of the generator to cancel engine vibrations due to rough idling and suppress body vibrations due to the rough idling. Irregular combustion of the engine is detected from a change in the engine speed, and a voltage higher than the output voltage of the generator is than applied across the field winding to increase the field winding current and hence the load torque on the generator, which induces vibrations on the generator body. When the generator vibrations and vibrations due to irregular combustion are in inverse phase relationship to each other, they are cancelled.

摘要： The present invention relates to an electrical protective circuit, used when abnormality occurs, in a vibration suppressing apparatus which changes the load torque on a generator such as an alternator fixed on the engine to generate an angle moment on the generator body to cancel rough idling engine vibrations to suppress vehicle body vibrations due to the rough idling. In the inventive vibration suppressing apparatus, a generator is fixed on the engine which generator includes a voltage regulator to control a field winding current such that a fixed voltage is output to a battery. The generation of engine rough idling is detected on the basis of either a change in the engine speed or a change in the engine vibrations. If rough idling is detected, a high voltage circuit is connected to the field winding to increase the field winding current and hence the load torque on the generator. In the inventive protective circuit, the battery voltage is compared with a predetermined reference value when no rough idling is detected. If the battery voltage exceeds the reference value, a changeover signal is generated and the high voltage circuit is disconnected from the field winding in response to the changeover signal.

摘要： In a vehicle vibration reduction control apparatus for controlling an alternator driven by an engine to charge a battery in such a way that vehicle body vibration due to the engine can be cancelled by alternator vibration, the reference voltage applied to an alternator field coil is reduced by a predetermined value for a predetermined time period, whenever battery terminal voltage exceeds a predetermined level. Since the battery charging rate can be reduced automatically at battery overcharge due to cancellation of engine vibration by alternator vibration, it is possible to prevent the battery from being overcharged when engine vibration increases at idling, for instance.

摘要： A method of reducing vibrations of a car body comprises a step of detection of rough which is irregular combustion in an engine, preferably through monitoring of angular velocity of a crankshaft of the engine, and a step of exerting such external force as will cancel roll vibrations of the engine caused by the rough on an engine block of the engine temporarily after the occurrence of the rough. A magnitude of the force and timing of exerting the force is preferably determined on the basis of a degree of the rough and the angular velocity immediately before the occurrence of the rough.

摘要： An apparatus and a method for detecting abnormal combustion in an internal combustion engine and an apparatus and a method for controlling vibration caused by abnormal combustion. The apparatus for detecting abnormal combustion includes a unit for detecting the rotation of an internal combustion engine, a unit for calculating rotation angular acceleration on the basis of the detected rotation, a unit for comparing the rotation angular acceleration at the position of a predetermined crank angle in one cycle of the operation of the internal combustion engine with a predetermined reference value, and a unit for judging from the comparison result whether abnormal combustion occurs in the internal combustion engine. The apparatus for reducing vibration caused by abnormal combustion offsets vibration caused by abnormal combustion and vibration of an electric generator to each other by passing a pulse-like field current in the electric generator in response to detection of abnormal combustion to generate vibration torque in the electric generator.

摘要： A method of detecting the condition of combustion in each cylinder of an internal combustion engine while monitoring a variation in rotation of a crankshaft in the engine for each cylinder, in which the degree of irregular combustion is judged based on the magnitude of the rotational variation, and/or in which the condition of combustion in a succeeding cylinder is judged based on the difference between rotational variations within one combustion period, of adjacent cylinders, and/or in which the rotational ascending rate within one combustion period, of each cylinder is detected to judge the condition of combustion in the cylinder based on the dropping state of the rotational ascending rate, and/or in which the rotational angular acceleration within one combustion period, of each cylinder is detected to thereby judge that a predetermined cylinder is in a condition of irregular combustion when the quantity of the variation in rotational angular acceleration between adjacent cylinders exceeds a predetermined value.

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 torque control unit rotates a motor machine having a motor element and a load element. The load element is coupled to the motor element via a rotational main shaft and driven to rotate by the motor element. Rotational acceleration at each rotation angle during one revolution of the rotational main shaft is detected and fed back. An electromagnetic torque of the motor element is controlled so that a difference between the electromagnetic torque of the motor element and a load torque of the load element may become zero at each rotation angle of the rotational main shaft.
