Publication number: 20230358162Abstract: Disclosed are an apparatus of injecting fuel for an engine and a method thereof. The apparatus of injecting fuel for an engine includes: a main injector positioned adjacent to an exhaust valve and injecting the fuel into a combustion chamber of the engine; and an auxiliary injector positioned adjacent to an intake valve and injecting the fuel into the combustion chamber of the engine later than injection time of the main injector, wherein the fuel injected from the main injector and the fuel injected from the auxiliary injector are injected into the combustion chamber in a tumble direction.Type: ApplicationFiled: December 6, 2022Publication date: November 9, 2023Inventors: Jonghyeok Lee, Dong Hee Han, Hyunjin Kang, Seungwoo Hong, Kwanhee Lee, Jaeheun Kim, Ingee Suh, Heechang Oh

Patent number: 11536207Abstract: An apparatus of controlling a vehicle and a method thereof are provided. The operating region of an engine is operated with theoretical air-fuel ratio. The apparatus includes a supercharger that supplies compressed air to a the combustion chamber of the engine and a spark plug that ignites mixed air supplied to the combustion chamber. An intake valve selectively opens and closes the combustion chamber for inflowing the mixed air therein. A variable valve apparatus adjusts an opening timing and closing timing of the intake valve and a controller adjusts an ignition timing of the spark plug and the closing timing of the intake valve through the variable valve apparatus based on the operating region of the engine.Type: GrantFiled: November 3, 2021Date of Patent: December 27, 2022Assignees: Hyundai Motor Company, Kia CorporationInventors: Yeongseop Park, Dong Hee Han, Jong Il Park, Hyunjin Kang, Heechang Oh, Jaun Ku, Seungwoo Hong, Jonghyeok Lee, Kwanhee Lee, Dongwon Jung, Jaeheun Kim
