SUPPORT DEVICE OF INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To suppress vibration by solving the problem of an increase in vibration when switching the mount characteristics (damping characteristics) of a negative pressure switching type engine mount. SOLUTION: Two systems of negative pressure switching type mounts 31 and 32 are provided to change damping characteristics by switching to a negative pressure or atmospheric pressure. An engine (internal combustion engine) 12 is supported on a car body frame (car body) 11 side through the negative pressure switching type mounts 31 and 32. The two systems of negative pressure switching type mounts 31 and 32 are provided with first and second conduits 33 and 34 for introducing a negative pressure or atmospheric pressure to them. A one-way valve 35 and orifice 36 for regulating flow rate of air are provided in parallel to one of the first and second conduits 33 and 34. COPYRIGHT: (C)2006,JPO&NCIPI
