Estimating the term…
An intake system for an internal combustion engine of a motor vehicle which includes a first unfiltered air intake (10) which is arranged at a location in the vehicle that is favorable for air intake, and a second unfiltered air intake (11) which is arranged at a location in the vehicle that is protected against road spray and splashes of water. The two unfiltered air intakes (10, 11) each open into a common line (12) which communicates with the internal combustion engine. In the first unfiltered air intake (10) there is a moisture sensor (14) which emits a signal when water enters the first unfiltered air intake (10). This signal actuates a drive member 23 which moves a flap 13 between first and second switching positions. In the first switching position, the flap 13 closes the second unfiltered air intake 11, so that no air can get into line 12 from the second unfiltered air intake 11. In the second position, the flap 13 closes the first unfiltered air intake 10, so that air gets into line 12 exclusively through the second unfiltered air intake 11.
An intake system for an internal combustion engine of a motor vehicle, comprising a first air intake, a second air intake, a valve member movable between first and second positions, an actuator which moves the valve member, and a controller which actuates the actuator, wherein the second air intake is arranged at a location protected against road spray and splashes of water, the first air intake and the second air intake each open into a common line leading to the internal combustion engine, the second air intake is blocked when the valve member is in the first position, and the first air intake is blocked when the valve member is in the second position;
