    ”Two hydraulically dampened engine mounts reduce the transmission of engine vibration to the passenger compartment. At idle, a pneumatically actuated solenoid allows engine vacuum to pull a positioning spring in the engine mount down, allowing the easier transfer of a glycol mixture through the mount, which softens the mount and reduces the transmission of engine vibration. At a speed of about 3 mph, the engine-control unit cuts off current to the solenoid valve, closing the hydraulic connecting channel between the two chambers. Now, the exchange of hydraulic fluid is through a smaller spiral-shaped channel, thus making the engine mounts firmer.”
