Claims

[Scope of utility model registration request]

In an internal combustion engine having a supercharger system in which an exhaust turbo supercharger is combined with an engine supercharger, a bypass path is connected to a direct path from an air cleaner to a compressor inlet side of the exhaust turbo supercharger,
Then, an intake control valve is provided, the bypass path is connected to the direct path again through the mechanical supercharger, and the engine output side drives the mechanical supercharger via an electromagnetic clutch, and the engine speed is detected. A sensor, an engine cooling water temperature detection sensor, a fuel injection pump rack position detection sensor, a shift lever position detection sensor, and an accelerator pedal depression amount detection sensor are respectively installed at predetermined positions, and the detection signals from these detection sensors are taken in to detect the intake air. 1. A control device for a mechanical supercharger, comprising a controller that outputs control commands to a control valve and an electromagnetic clutch.
