Controllable engine mounts

The engine has engine mounts that can be enabled, familiar from vehicles with diesel engines. The engine mounts that can be enabled are set by means of partial vacuum to hard or soft to ensure a comfortable start and idling of the combustion engine. As soon as the partial vacuum is no longer applied to the engine mounts, they are switched to hard. The electric changeover valve of the controllable engine mounts is activated by the Digital Engine Electronics (DME).
