Abstract:
Vibration damping for accessory items of an engine is improved. An engine according to a first embodiment of the present invention is provided with a plurality of accessory items that vibrate in a direction parallel to the crankshaft of the engine, the plurality of accessory items being provided so as to shift the phase of the resonance point of a frequency response function. An engine according to a second embodiment of the present invention is provided with a first accessory item disposed along a direction orthogonal to the crankshaft of the engine, and a second accessory item installed in the flywheel housing of the engine, the support rigidity of the first accessory item and the support rigidity of the second accessory item being set to proximate values, whereby the characteristic frequency of the first accessory item and the characteristic frequency of the second accessory item are caused to come closer to each other.
