摘要： The present invention relates to an apparatus for effectively reducing vibrations of a vehicle engine and the vehicle body due to irregular combustion of the engine. In the inventive vibration suppressing apparatus, a generator (4) is provided which has a voltage regulator (9) to control a field winding (8) current so as to output a constant voltage to a battery (1). When irregular combustion of the engine is detected on the basis of a change in the engine speed, a voltage higher than the output voltage of the generator (4) is applied across the field winding (8) to increase the load torque on the generator (4). A change in the load torque of the generator (4) induces vibrations on the generator body due to reaction. When the generator vibrations and vibrations due to irregular combustion are in inverse phase relationship to each other, they are cancelled by each other to suppress those vibrations.

摘要： A method of reducing vibrations of a car body (13) comprises a step of detection of rough which is irregular combustion in an engine (11), preferably through monitoring of angular velocity of a crankshaft of the engine (11,) and a step of exerting such external force as will cancel roll vibrations (A1) of the engine (11) caused by the rough on an engine block of the engine (11) 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.
