DEVICE FOR REMOVING ENGINE VIBRATION AND ENGINE WHOSE STROKE CHARACTERISCTS ARE VARIABLE

Document Type and Number:

WIPO Patent Application WO/2006/049294

Kind Code:

A1

Abstract:

A device for removing engine vibration, capable of effectively removing secondary vibration cause by reciprocation of a piston (21) of a multilink-type variable compression ratio engine (E). The secondary vibration can be removed even if the direction of the secondary vibration is inclined relative to the cylinder axis (L1), and the removal is made by inclining the direction (see the arrow direction) of vibration exciting force, produced by a secondary balancer device (43), so that it matches the direction of the secondary vibration. The secondary balancer device (43) is constructed by having balancer weights (44a, 45a) respectively supported by a pair of balancer shafts (44, 45) rotating in the directions opposite from each other. Displacing the phases of the balancer weights (44a, 45b) enables the direction of the produced vibration exciting force to be inclined so that it matches the direction of the secondary vibration of the engine (E).
