20120118273 | CANISTER FOR VEHICLES AND FUEL EVAPORATIVE SYSTEM PROVIDED WITH THE SAME - 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. The canister may include an evaporation gas supply passage connected to the fuel tank and receiving the evaporation gas, an air passage selectively receiving the air from the exterior, a purge passage supplying the evaporation gas to the engine according to flow of the supplied air, and a heating module heating a position at which the air passing through the air passage flows in the canister, or mounted at the air passage and heating the air flowing in the canister, wherein the heating module comprises a heating core for heating the air flowing in the canister, and a diffusing plate disposed between the air passage and the heating module and diffusing the air passing through the air passage so as to be heated at the heating core evenly. | 05-17-2012 |
20130133855 | HEAT EXCHANGER FOR LPI VEHICLE - 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. | 05-30-2013 |
20130146025 | FUEL SUPPLY SYSTEM OF VEHICLE - 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. | 06-13-2013 |
20130146145 | DEVICE AND METHOD FOR REDUCING TEMPERATURE OF BOMBE USING LATENT HEAT OF LPG VAPORIZATION - 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
