Abstract
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.
