Patent number: 7025038Abstract: A fuel rail in a variable intake module is integrated, thereby obtaining a sufficient coupling area and excellent sealing between the variable intake module and intake manifold. The assembly of injector and variable intake module to an engine is improved. A high pressure fuel path is integrally formed at a lower inner side of the variable intake module, wherein the variable intake module includes a plurality of intake paths and a flap placed at each intake path to form a tumble. Furthermore, an injector insertion part is formed at a lower side of each intake path to communicate with the high pressure fuel path.Type: GrantFiled: October 27, 2004Date of Patent: April 11, 2006Assignee: Hyundai Motor CompanyInventor: Chul-Ho Yu

Patent number: 6928997Abstract: An exhaust-valve-side portion of a bottom surface of a bowl is connected to an upper surface of a piston by a smoothly curved surface. Therefore, a separation of a tumble flow can be minimized and air flow introduced into the bowl is more strongly tumbled. Fuel mixed with the air flow is also introduced into the bowl, so a generation of a carbon layer that is caused by contact of fuel and oil with the wall can be prevented. A width of the exhaust-valve-side portion of the bowl is greater than a width of the intake-valve-side portion of the bowl and the side walls of the bowl are formed as curved surfaces. The intake valve pocket is formed as a single groove, accumulation of carbon can be minimized, and propagation of a flame during the combustion occurs easily.Type: GrantFiled: November 17, 2004Date of Patent: August 16, 2005Assignee: Hyundai Motor CompanyInventor: Chul Ho Yu
