Publication number: 20230242094Abstract: Methods and systems are described for a hybrid vehicle with a passive prechamber combustion engine. The system includes a passive prechamber combustion engine, an electric motor, and a controller communicatively coupled to the combustion engine and the electric motor. The combustion engine is configured to operate at engine loads satisfying a load threshold. The controller is configured to determine whether an engine load falls below the load threshold. The controller is configured to select the electric motor to propel the vehicle. The controller is configured to determine whether the engine load satisfies the load threshold. The controller is configured to select the combustion engine to propel the vehicle for providing efficient fuel consumption associated with prechamber ignition in response to determining that the engine load satisfies the load threshold.Type: ApplicationFiled: January 31, 2022Publication date: August 3, 2023Inventors: Mayuri Wagh, Mark Shirley, Nahm Roh Joo, Mark Bourcier, Antowan Zyada, Jeffrey Hollowell, Philip Zoldak

Patent number: 11459995Abstract: Methods and systems are described for combustion engine mode optimization. The system includes a combustion engine, a fuel delivery system, and a controller communicatively coupled to the combustion engine and the fuel delivery system. The controller selects a low temperature combustion mode based on the combustion engine being warmer than a predetermined temperature and low load conditions on the combustion engine. The low temperature combustion mode includes instructions that reduces an intake valve opening duration and an exhaust valve opening duration. The controller reduces the intake valve opening duration and the exhaust valve opening duration to create a delay between an intake valve opening duration and an exhaust valve opening duration in response to selecting the low temperature combustion mode. The delay increases a residual gas temperature in the combustion chamber and induces auto-ignition of fuel in the combustion chamber.Type: GrantFiled: January 5, 2022Date of Patent: October 4, 2022Assignees: Hyundai Motor Company, Kia CorporationInventors: Antowan Zyada, Kyoung Pyo Ha, Shengrong Zhu, Philip Zoldak, Jeffrey Hollowell, Mark Shirley, Nicholas Fantin

Publication number: 20220275748Abstract: An ignition promoter assembly includes: an ignition device to ignite a mixture of fuel and air; and a passive pre-chamber body that defines: a cylindrical fitting space into which the ignition device is inserted, and a secondary combustion space along with an end of the inserted ignition device. In particular, the passive pre-chamber body fluidly communicates with a main combustion chamber disposed outside an exterior surface of the passive pre-chamber body through a flow channel, and the passive pre-chamber body includes: a cylindrical main body portion defining the cylindrical fitting space; and an end portion continuously extended from the cylindrical main body portion and at least partially exposed to the main combustion chamber. In particular, the flow channel is formed in the end portion of the passive pre-chamber body, and a volume of the cylindrical fitting space is greater than a volume of the secondary combustion space.Type: ApplicationFiled: February 26, 2021Publication date: September 1, 2022Applicants: HYUNDAI MOTOR COMPANY, KIA MOTORS CORPORATIONInventors: Mark SHIRLEY, Philip ZOLDAK, Mayuri WAGH

Patent number: 10316802Abstract: An exhaust gas recirculation valve device for a vehicle includes: a mixer tube extending between an inlet end and an outlet end, a first plate at the inlet end, and a second plate at the outlet end. The mixer tube having a plurality of divider walls extending radially between the longitudinal axis and the outer wall longitudinally from the inlet to the outlet. The divider walls defining a plurality of mixing chambers therebetween for receiving and storing exhaust gas from a dedicated engine cylinder. The first plate rotatably disposed at the inlet end of the tube, and the second plate rotatably disposed at the second end of the mixer tube to selectively block off at least one chamber at the inlet and outlet ends, respectively. The mixer configured to capture and distribute recirculated exhaust gas corresponding to an operating speed of the engine.Type: GrantFiled: March 28, 2017Date of Patent: June 11, 2019Assignees: HYUNDAI MOTOR COMPANY, KIA MOTORS CORPORATIONInventor: Mark Shirley
