The supercharge method of a supercharge system, an internal-combustion engine, and an internal-combustion engine

Japanese Patent JP6205994

B2

Provided is a supercharging system (2) in which an air intake passage (4) of an engine (1) is provided with an S/C (speed up ratio-adjusting supercharger) (10) driven by the engine (1), for adjusting the speed up of the rotating speed of a screw rotor (22) for compressing the intake air, wherein the system is provided with a bypass passage (11) for bypassing the S/C (10) and a bypass valve (12) for adjusting the flow rate passing through the bypass passage (11), and moreover provided with an ECU (control device) (13) for adjusting the speed up ratio of the S/C 10 and the opening of the bypass valve (12), and controlling the supercharging pressure intaken into the engine, to a target supercharging pressure based on the rotating speed of the engine (1) and the output torque output by the engine (1). The supercharging pressure intaken into the engine is thereby brought to the target supercharging pressure based on the rotating speed of the engine (1) and the output torque of the engine (1), over the entire operating range of the engine (1).
