燃機関の過給制御装置。[Claims for Utility Model Registration] 1. A supercharging control device for an internal combustion engine consisting of the following elements, a mechanical supercharger disposed in the intake pipe of the internal combustion engine, and a mechanical supercharger selected as the rotating shaft of the internal combustion engine. an exhaust-type supercharger with a compressor installed in a bypass intake pipe that bypasses the intake pipe in which the mechanical supercharger is installed; a first non-return valve; a bypass control means for performing bypass control of the exhaust type supercharger in response to the pressure between the compressor and the first non-return valve; the pressure increases to a level close to a pressure controlled by the bypass means; means for releasing the clutch means when 2. The throttle valve of the internal combustion engine is installed upstream of the mechanical supercharger and the exhaust supercharger, and the bypass control means controls the pressure between the compressor and the first check valve between the throttle valve and the supercharger. The internal combustion engine according to claim 1, which is controlled by the differential pressure between the intake pipe pressures and which is further provided with a second check valve on the discharge side of the mechanical supercharger. Engine supercharging control device.
