Abstract
An intake system for a supercharged engine can include a blow-off passage provides communication between the upstream side of the throttle valve and the upstream side of a supercharger. A blow-off valve opens and closes the blow-off passage. The blow-off valve can be configured to open and close based upon pressure on the downstream side of the throttle valve. The present intake system can further comprise a first conduit providing communication between the upstream side of the throttle valve and the blow-off valve, a second conduit providing communication between the downstream side of the throttle valve and the blow-off valve, and a solenoid valve for switching between the first and second conduits.
