摘要： Provided is a turbocharger system capable of ensuring a sufficient EGR amount in all operating conditions, and reducing NOx emission from an engine. A turbocharger system for an engine includes an EGR controller that recirculates a part of exhaust gas discharged from an engine to an intake side, and a turbocharger. In the turbocharger system, the turbocharger is provided with a power-assisted turbocharger including an electric motor (2c) that assists a drive force of a compressor (2b). The EGR controller controls an amount of exhaust gas recirculated to the intake side so as to inhibit the generation of NOx regardless of an amount of oxygen necessary for combustion of the engine. An electric motor control unit (23) is provided to drive the electric motor (2c), by the control of the EGR controller, when the amount of oxygen necessary for the combustion of the engine is deficient.

摘要： Provided is an engine system capable of immediately restarting an engine upon detecting a driver's reaccelerating operation while an engine speed is decreased by idle-stop control. In an engine system (1) including an idle-stop control unit (26) which performs the idle-stop control of stopping a fuel injection to an engine (2) when the engine (2) idly rotates upon stopping the vehicle by connecting an electric assist turbocharger (4) obtained by the combination of a turbocharger and a motor (3) to an intake and exhaust system of the engine (2), the idle-stop control unit (26) is configured to restart the engine (2) by resuming the fuel injection to the engine (2) while operating a motor (3) upon detecting the reaccelerating operation during the idle-stop control.
