気筒エンジンの回転変動抑制装置。[Scope of Claim for Utility Model Registration] Determining whether or not the engine is in an idling operating state in a multi-cylinder engine that calculates the fuel injection amount for each cylinder and injects fuel independently using an injector provided for each cylinder. an idling determination means for determining engine speed during idling, a cylinder-by-cylinder rotational speed fluctuation detection means for detecting engine speed fluctuations during a predetermined period of the explosion stroke of each cylinder during idling, and calculating an average value of rotational speed fluctuations for all cylinders during idling. An average rotational speed variation calculation means and a correction means for comparing the engine rotational speed variation for each cylinder with the average rotational speed variation for all cylinders and correcting the fuel injection amount for each cylinder so that the former approaches the latter. A rotational fluctuation suppression device for a multi-cylinder engine, which is characterized by:
