Abstract

The system has two untreated air inlets connected to a common line to the engine. The second inlet is protected against splash and bilge water and can be closed by a closure element in a first position. The first inlet can be closed by the closure element in a second position. The closure element is movable by a motion unit, which is connected to a moisture sensor control unit with electrically conducting sensor wires and a control signal output. The system has two inlets (10,11) for untreated air connected to a common line to the engine, a closure element and a motion unit (17). The second air inlet is at a position protected against splash and bilge water and can be closed by the closure element in a first position. The first inlet can be closed by the closure element (13) in a second position. The closure element is movable by the motion unit, which is connected to a control element in the form of a moisture sensor (14) with at least two electrically conducting sensor wires at a distance apart and a signal output for controlling the motion unit.
