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.
