摘要： An engine system includes an engine with a combustion chamber, an intake line in which external air flows, and an exhaust line in which exhaust gas flows. A compressor is disposed in the intake line and rotated with a turbine to compress external air. A first recirculation line is branched off from the exhaust line and merged into the intake line. An EGR cooler cools exhaust gas flowing through the first recirculation line. A second recirculation line is branched off from the first recirculation line. A bypass line is branched off from the first recirculation line between an electric supercharger and the EGR cooler. A three-way valve is disposed where the bypass and first recirculation lines join. An intake valve is disposed in the intake line between where the first recirculation line and intake valve join and where the bypass line and intake valve join.

摘要： An apparatus and a method for controlling a hybrid vehicle are provided. The apparatus includes an engine that generates power by combusting fuel and a drive motor that supplements the power from the engine and operates selectively as an electric generator to produce electrical energy. A clutch is disposed between the engine and the drive motor and a battery supplies electrical energy to the drive motor and is charged with the electrical energy produced by the drive motor. Multiple electric superchargers are installed in multiple intake lines through which outside air to be supplied into a combustion chamber of the engine flows. A controller determines an operation mode of the multiple electric superchargers based on required power of a driver and a state of charge (SOC) of the battery and adjusts the power output from the engine and the power output from the drive motor.
