Abstract
An intake system for an internal combustion engine of a motor vehicle, which includes a first air intake which is arranged at a point in the motor vehicle that is advantageous for air intake, and a second air intake which is arranged at a point that is protected from road spray and splashes of water. The two air intakes end in a common line that communicates with the internal combustion engine. In the first air intake a moisture sensor is arranged. When water enters into the first air intake this moisture sensor emits a signal that actuates a solenoid to move a pivotable valve In a first switching position pivotable valve closes the second air intake so that no air reaches line from the second air intake In a second position (shown in broken lines) pivotable valve closes the first air intake so that air reaches line only through the second air intake
