ABSTRACT:
A suction system for an internal combustion engine has a device for avoiding the ingress of water and includes a switch-over valve between a primary intake line and a secondary intake line. To provide improved protection against water ingress, the switch-over valve is controlled so that during off-road travel there is a change-over from a primary air intake to a secondary air intake.
