Abstract

A canister for a vehicle, and more particularly, a canister with dual air flow paths is configured to divide an inner space of an air entrance of the canister into two spaces and allow air to flow in from an outdoor atmosphere through one space between two spaces in a purging operation and discharge fuel evaporation gas to the outdoor atmosphere through the other space when the fuel evaporation gas is discharged in order to prevent pressure in a fuel tank from being raised.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2010-0123300 filed on December 6, 2010, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a canister for use in a vehicle, and more particularly, the present invention relates to a canister having a dual air flow path configuration that connects the air inlet of the canister to The internal space of is divided into two spaces, and the air from the external atmosphere is flown in through one of the two spaces in the purge operation, and the fuel boil-off gas is discharged through the other space when the fuel boil-off gas is discharged. to the outside atmosphere, thereby preventing pressure build-up in the fuel tank. Background technique [0004] The fuel system device of the vehicle is a device for storing and supplying the fuel consumed in the engine, which...
