Title:
内燃機関運転停止時回転制御装置
Document Type and Number:
Japanese Patent JP4029581
Kind Code:
B2
Abstract:
A control apparatus (40,48,50) for suppressing vibrations of an engine (2) when combustion is stopped. The control apparatus maintains an engine rotational speed (NE) at a reference rotational speed for a reference time when the combustion of the engine is automatically stopped. This results in a reduction in pressure in a combustion chamber of the engine. The control apparatus gradually reduces the rotational speed of the crankshaft, and stops the crankshaft before the rotational speed of the crankshaft reaches a resonant speed. In this way, the resonance and increased pressure in the combustion chamber are prevented to reduce vibrations of the vehicle.
