Abstract
An intake system has a recirculation passage, through which supercharging air discharged from a supercharger is recirculated into the supercharger, and a recirculation control valve disposed in the recirculation passage, by which the recirculation passage is gradually opened and closed as the pressure of supercharging air downstream from the supercharger changes between a low specified pressure, below the atmospheric pressure, and a high specific pressure, above the atmospheric pressure. The air intake system further has a bypass passage, for allowing air to bypass an intercooler, which is opened and closed by a bypass control valve at an interim specified pressure between the high and low specified pressures.
