    Abstract: An engine system according to an exemplary embodiment of the present invention may include an engine including a plurality of cylinders; a fuel separator separating into a low-octane fuel and a high-octane fuel based on an octane number; a cylinder deactivation device deactivating some cylinders among the plurality of cylinder based on a driving region; a low-octane fuel injector injecting the low-octane fuel separated by the fuel separator into the plurality of cylinder; a high-octane fuel injector injecting the high-octane fuel separated by the fuel separator into the activated cylinders without being deactivated by the cylinder deactivation device; and a controller configured to control the cylinder deactivation device to deactivate some cylinders or activate all the cylinders, and to control the low-octane fuel injector and the high-octane fuel injector to inject the low-octane fuel or the high-octane fuel into the cylinders.

    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.
