However, even if it is possible to qualitatively understand how the interrelationship of the exhaust turbine and blower specifications affects the performance of the turbocharger, it is difficult to quantify it strictly. The present invention is intended to solve the above-mentioned difficulties, and in the present invention, the blower driven by the exhaust turbine is An inlet guide vane is provided whose inclination angle is automatically controlled using one or both of them as control factors. The inlet guide vanes on the blower and its automatic control system serve to improve the performance of the blower over a wide operating range of the engine.
