摘要： A returnless fuel supply system applicable to an LPG vehicle is provided. The system supplies LPG fuel from an LPG bombe to an engine at a predetermined pressure or greater and prevents the generation of vapor in the LPG fuel, thereby eliminating a need to return a portion of the LPG fuel supplied to the engine to the LPG bombe. Through the application of the returnless fuel supply system that does not return the high temperature fuel to the LPG bombe, the cause of the internal pressure increase in the LPG bombe is eliminated, and thus efficient refueling of LPG bombe with LPG fuel is achieved.

摘要： A controller of a fuel system for a vehicle is provided in which heat is dissipated outside from a printed circuit board to cool the controller. The dissipated heat is utilized to maximize the efficiency of the purge operation using a canister by waste heat. The controller is integrated with an air filter for removing foreign substances from air to be suctioned into a canister, and is configured to realize heat exchange between air passing through the air filter and a motor driver.

摘要： A fuel system for a vehicle includes a fuel evaporation gas treatment system configured to control fuel evaporation gas generated inside a fuel tank. The fuel evaporation gas treatment system includes: a gas collection chamber configured to store the fuel evaporation gas discharged from the canister through an atmosphere line connected to the canister; and an outlet of the gas collection chamber is connected to a purge line through a gas intake line so that the fuel evaporation gas stored in the gas collection chamber flows into an engine through the gas intake line and the purge line.
