Vibrating decrease structure of multi- link type engine

摘要

P To provide a structure for reducing vibrations of a dual-linkage engine and which reduces lateral vibrations relative to a direction of piston movement by a simple configuration. PSOLUTION: The structure for reducing vibrations of a dual-linkage engine 100 includes: an upper link 13, one end of which being coupled to a piston 11 via a piston pin 16; a lower link 14 coupled to the other end of the upper link 13 via an upper pin 17 and also rotatably coupled to a crankpin 12A of a crankshaft 12; and a control link 15, one end of which being coupled to the lower link 14 via a control pin 18 and also the other end of which being slidably coupled to slidable shaft 21. In the structure and a balance weight 15B is provided in an end ON a slidable shaft side of the control link 15. PCOPYRIGHT: (C)2012 and JPO& INPIT
