The apparatus includes receiving a selection of at least one text region from displayed text, determining at least one classification for one of the at least one text region and the character information based on a connection relationship between at least one piece of character information included in the at least one text region selected, and processing a text related function associated with the at least one piece of character information according to the determined at least one classification.

Abstract: An electronic device is provided. The electronic device includes a Subscriber Identity Module (SIM) card configured to store SIM information, a control module configured to combine the SIM information with stored address information on a server device to create combined address information, to control a connection with the server device based on the combined address information, and to control a reception of a list of applications comprising information related to application installation or update corresponding to a type of the SIM information, and a communication module configured to establish communication with the server device.

Abstract: An oil supply device includes a plurality of hollow cam shafts, cam shaft journals, and a shaft side path. The hollow cam shafts have through holes that pass in a longitudinal direction from interior to exterior thereof. The cam shaft journals are provided on every position at which the through holes are formed. Each of the cam shaft journals has a path connected with an associated through hole and is coupled with a cylinder head. The shaft side path is formed to supply oil into each hollow cam shaft after the oil sequentially passing from an oil pump through an associated cam shaft journal and an associated through hole.

Abstract: 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.

Abstract: The engine throttle body for inducing a smooth mixture of air and EGR gas regardless of the openness of a valve flap makes it possible for an engine to operate under a super thin air condition through the even mixture between air and EGR gas during a low engine load, thereby improving fuel consumption and reducing the exhaust of nitrogen oxide.

Abstract: 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.

Abstract: A gasoline direct injection engine system provided with an air rail for supplying air and a fuel rail for supplying fuel comprises an air supply for adjusting the flow rate of intake air, pressurizing the intake air, and supplying the pressurized air to the air rail. A fuel supply pressurizes the fuel from a fuel tank and supplying the pressurized fuel to the fuel rail. At least one injector assembly is connected to both the air rail and the fuel rail, forming an air-fuel mixture and injecting the air-fuel mixture into a cylinder of an engine.

Abstract: A fuel injection control method using a system comprising a high-pressure pump for pumping fuel, a fuel-pressure control valve disposed in a fuel bypass line communicating an output port and an input port of said high-pressure pump, and a controller for regulating fuel pressure, is provided. The method comprises: monitoring engine operating conditions; determining an optimal fuel injection pressure on the basis of said monitored engine operating conditions; determining on/off timing and on/off duration of said fuel-pressure control valve such that fuel pressure inside a fuel rail approaches said optimal fuel injection pressure; and opening and closing said fuel-pressure control valve according to said determined on/off timing and on/off duration of said fuel-pressure control valve.
