ABSTRACT:
A supercharging pressure control device for an engine having a supercharger, which is driven by the engine and disposed in an intake passage downstream of an engine throttle valve, includes a bypass passage. The bypass passage connects a part of the intake passage, upstream from the supercharger and downstream from the engine throttle valve, and a part of the intake passage downstream from the supercharger. A bypass valve is disposed in the bypass passage. The bypass valve is controlled so as to allow intake air to bypass the supercharger at a controlled flow rate.
