Abstract:
1. An engine mount system for managing vehicular vibrations, comprising: a housing having a first end and a second end, the second end coupled to a vehicle structure; a first compliant member coupled to the housing proximate the first end; an inertia track assembly coupled within the housing forming a first fluid chamber with the first compliant member and forming a second fluid chamber with the second end, the inertia track assembly having at least first and second passageways there through for conducting fluid between the first fluid chamber and the second fluid chamber, the first passageway having a substantially greater flow resistance than the second passageway and the second passageway having a substantially shorter length than the first passageway, the inertia track assembly including a first vacuum chamber and an idle-track bypass mechanism disposed in the second passageway for opening and closing the second passageway; a first port in communication with the first vacuum chamber; a second port in communication with the idle-track bypass mechanism; and first and second switches coupled to the first and second passageways, respectively, for selectively enabling the first and second passageways to control fluid displacement between the first fluid chamber and the second fluid chamber, wherein a first pressure is applied to the first port and a second pressure is applied to the second port in a highway cruise state of the vehicle and the first pressure is different than the second pressure.
