Abstract

PURPOSE:To aim at the improvement of accurate control of the title supercharger by controlling at the downstream from an engine-driven supercharger the supercharging pressure according to the pressure at the upstream from a throttle valve when an exhaust turbosupercharger is operated alone with the operation of the engine-driven supercharger stopped. CONSTITUTION:The intake passage 2 of an internal combustion engine has an exhaust turbosupercharger 4 equipped at its downstream side and also an engine-driven supercharger 5 equipped at its downstream. An exhaust gas pas sage 3 has a waste gate valve 18 provided on it to make a part of the exhaust gas by-pass an exhaust gas turbine 4a of the exhaust turbosupercharger 4 and also has an actuator 19 provided on it to control the supercharger pressure of the intake passage 2 upon adjusting the valve opening power of the valve 18. A throttle valve 7 is to be provided on this device at the downstream from the engine-driven supercharger 5 on the intake passage 2. The supercharger pressure at the upstream from the throttle valve 7 is introduced into the actua tor at the downstream from the engine-driven supercharger 5.
