Abstract: A fuel supply system of a vehicle, may include a fuel tank storing ethanol therein, a main injector installed at an engine to inject the ethanol from the fuel tank, a heater provided to heat the ethanol supplied from the fuel tank to the engine, a cold-starting injector installed at the engine to inject the ethanol heated by the heater, and a valve unit connected to the main injector and the cold-starting injector and performing a switching operation between a state of the ethanol being supplied from the fuel tank to the main injector and a state of the ethanol heated by the heater being supplied to the cold-starting injector.

Abstract: A device for reducing the temperature of a bombe, which stores liquefied petroleum gas (LPG) fuel and may be connected to a fuel supply line for supplying the fuel to an injector, using latent heat of LPG vaporization, may include a fuel pump installed in the bombe and connected to an end of the fuel supply line for pressurizing the fuel, a cut-off valve installed in the fuel supply line for selectively cutting off fuel supply to the injector, a fuel collection line branched from the fuel supply line to the inside of the bombe for collecting the supplied fuel into the bombe when the cut-off valve may be closed, and an injection nozzle connected to the fuel collection line and injecting the fuel collected through the fuel collection line into the inside of the bombe.

Abstract: The heat exchanger may include a pipe unit mounted on a refrigerant line connecting a compressor with an evaporator of an air conditioning and adapted to flow a refrigerant and a LPG fuel returned from the engine, a first connecting member mounted at an end of the pipe unit to connect the pipe unit with the refrigerant line where the refrigerant line is connected to the compressor, and a second connecting member mounted at the other end of the pipe unit to connect the pipe unit with the refrigerant line where the refrigerant line is connected to the evaporator. The heat exchanger is configured so that the high-temperature LPG fuel is capable of exchanging heat with the refrigerant.

Abstract: A canister for a vehicle is provided with charcoal therein so as to absorb evaporation gas evaporated at a fuel tank, supplies air by pressure difference formed due to engine purge, and thereby releases the absorbed evaporation gas so as to supply the evaporation gas to an engine and to be burned therein again.

Abstract: A fuel pump for LPG (liquefied petroleum gas), may include a main bracket that may be mounted at a fuel tank, an integrated bracket that an end thereof may be fixed to the main bracket, the other end thereof may be extended to an inner side of the fuel tank, and the whole of the bracket may be integrally formed, and a pump unit that may be fixed to the other end of the integrated bracket with a space therebetween so as to pump liquefied fuel to an engine.

Abstract: An apparatus and method for partially driving a plasma display panel (PDP) includes a PDP with a plurality of bus electrodes, and a plurality of addressing electrodes intersecting the plurality of bus electrodes to create a display area for displaying an image frame. A panel driver selectively drives the plurality of bus and addressing electrodes, and a controller controls the panel driver to exclude from driving at least one among the plurality of bus electrodes and addressing electrodes with respect to a partial area of the PDP. By only partially driving a portion of the PDP, the loads to be driven, costs of the driving, and power consumption can be reduced. Further, the quality and the brightness of an image can be improved by increasing the number of subfields or increasing a sustaining period by an amount of time corresponding to the time saved by excluding the partial area from driving.

Abstract: Apparatus and method for improving quality of an input image. The apparatus includes a contrast module for adjusting contrast of input image data; a luminance module for adjusting luminance of the input image data; and an average picture level detector for calculating an average picture level of the input image data, wherein the apparatus controls more than one of the luminance module and the contrast module based on the average picture level outputted from the average picture level detector to improve the quality of the input image. The image quality can be greatly improved by adding simple algorithm and circuitry.
