    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.

    Abstract: An exhaust gas combustion system advances exhaust timing by using an electric CVVT apparatus. The system may include: an air supply passage adapted to provide for passing air to be supplied to an engine; an exhaust manifold adapted to transmit exhaust gas of the engine to an exhaust passage; an air injection passage adapted to connect the air supply passage with the exhaust manifold so as to supply a part of air passing through the air supply passage to the exhaust manifold; and an air valve disposed at the air injection passage so as to selectively open or close the air injection passage. Unburned gas melded in exhaust gas may be combusted according to air supplied to the exhaust manifold.

    Abstract: A control apparatus of an engine for a hybrid vehicle includes an engine including at least one cylinder that generates power required for vehicle driving by fuel combustion, an injector that injects fuel into the cylinder, a driving motor that assists the power of the engine, and a controller that selectively performs a single injection mode in which fuel is injected once into the cylinder of the engine through the injector and a multiple injection mode in which fuel is injected a plurality of times into the cylinder of the engine through the injector, in a transition region that transitions from a theoretical air-fuel ratio operating region in which the engine is operated at a theoretical air-fuel ratio to a lean-burn combustion operating region in which the engine is operated leaner than the theoretical air-fuel ratio.
