Abstract: A variable compression ratio engine (1) is provided with a multi-link mechanism (101) between a piston (102) and a crankshaft (103). The multi-link mechanism (101) includes an upper link (104), a lower link (105) and a control link (106). An anti-vibration device (6) for vehicles is attached between the upper part of the engine (1) and a vehicle body to which the engine (1) is mounted. The anti-vibration device (6) includes a rod body (63) having a first elastic connecting part (61) at one end and a second elastic connecting part (62) at another end. The first elastic connecting part (61) is connected to the engine (1). The second elastic connecting part (62) is connected to the vehicle body.

Abstract: An amplification device for amplifying suction noise of a vehicle is disclosed herein. An embodiment of the amplification device comprises an intake duct, a connecting pipe, an elastic membrane member and a contact member. The intake duct feeds air into an engine inlet port. A connecting pipe is connected to an interior of the intake duct. The elastic membrane member blocks a passageway inside of the contacting pipe. The contact member is connected to the connecting pipe and includes at least one portion that is adapted to selectively contact a surface of the elastic membrane member that faces the intake duct.
