Abstract

A vehicle engine mount system comprises a housing and an inertia track assembly that forms a first fluid chamber with an upper compliant member and a second fluid chamber with the second end of the housing. The inertia track assembly has first and second passageways therethrough for conducting fluid between the first and second fluid chambers. The first passageway has a substantially greater flow resistance than the second. First and second switches are coupled to the first and second passageways, respectively, for selectively enabling the first and second switches to control fluid displacement between the first fluid chamber and the second fluid chamber.
