  • Moisture excluding air intake system for an internal combustion engine
    Patent number: 6453866
    Abstract: 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.
