るようにした内燃機関の軸受騒音防止装置。 In an internal combustion engine, a bearing cap is attached to a bearing formed in a cylinder block of the engine, and the crankshaft is supported by the cap on the side opposite to the piston. Therefore, a bearing noise prevention device for an internal combustion engine is configured to operate the ceramic actuator to reduce the clearance between the cap and the crankshaft only at the moment when the crankshaft vibrates the cap.
