Abstract
Methods and systems are provided for controlling an airflow to an engine via a primary air induction pathway or a secondary air induction pathway, where the secondary air induction pathway routes the airflow to the engine via a deployable snorkel system. Thus, in one example, a method comprises routing the airflow to the engine solely via the primary air induction pathway by commanding open a first air inlet valve and commanding closed a second air inlet valve, and responsive to a request to switch the routing, commanding closed the first air inlet valve and commanding open the second air inlet valve. In this way, the snorkel system may selectively be used in response to requests from a vehicle operator.
