<P>PROBLEM TO BE SOLVED: To provide a vibration reducing structure for a multi-link engine capable of reducing vibrations in a transversely oriented direction with respect to a piston movement direction using a simple configuration. <P>SOLUTION: The vibration reducing structure for the multi-link engine 100 is provided with an upper link 13 coupled to a piston 11 by a piston pin 16, a lower link 14 coupled to the upper link 13 by an upper pin 17 and rotatably coupled to a crank pin 12A, and a control link 15 coupled to the lower link 14 by a control pin 18 and rockably coupled to a rocking shaft 21. The upper link 13, the lower link 14 and the control link 15 are configured such that inertia forces of at least one prescribed order of second or higher order in terms of an engine rotational speed act on at least the upper link 13 and the control link 15 in a direction oriented transversely leftward and rightward with respect to a piston movement direction with a sum of leftward and rightward inertia forces of the prescribed order of the respective links balanced. <P>COPYRIGHT: (C)2010,JPO&INPIT |
