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： A control apparatus for a hybrid vehicle includes an engine that combusts fuel to generate power. A drive motor assists the engine power and selectively operates as a generator to generate electrical energy. A clutch is disposed between the engine and drive motor. A battery supplies electrical energy to the drive motor or is charged by the generated electrical energy. A DC converter transforms a DC from the battery. An electric supercharger supplies supercharged air to the engine. A controller determines an optimal air amount to maximize system efficiency based on a drive motor limited output value determined by a battery SOC, and determines an output drive motor power output and an output engine power output based on the optimal air amount when an atmospheric pressure is less than a predetermined pressure, intake temperature is greater than a predetermined temperature and the SOC is less than a predetermined value.
