Abstract
An hydraulic mount providing double idle rate dip frequencies of dynamic stiffness, the idle rate dips being vibration orders of an internal combustion engine corresponding to one and two times firing frequencies. The double idle rate dip is achieved by providing the first idle rate dip at the first vibration order via resonance tuning of the idle inertia track, and providing the second idle rate dip at the second vibration order via additional resonance tuning of a tunable air conduit.
