SYSTEM FOR RETURNING FUEL OF LPI HYBRID VEHICLE

摘要

A system for returning fuel in an LPI hybrid vehicle is provided to prevent the leakage of the injector by processing the fuel remaining in the injector line when the ignition key is off or in case of hot soaking. A system for returning fuel in an LPI hybrid vehicle comprises a canister for collection, an on/off valve(12), and a CCV valve(14). The canister is connected to a fuel return line of the LPI fuel feeding system through a residue fuel recovery line(10) and collects the fuel remaining in the fuel return line. The on/off valve is installed on the fuel recovery line and opens/closes according to on/off of an ignition key to control the returned fuel. The CCV valve is installed on a standby line(13) of the canister and maintains the atmospheric pressure condition within the canister when collecting the residual fuel.
