Problems solved by technology

In addition, in a vehicle in which a turbocharger is installed, the negative pressure of the engine intake system (such as the intake manifold) is relatively low, so it is difficult to perform the operation of purging the canister
In such a low-purification engine, the generation of fuel vapors is likely to exceed the collection capacity of the carbon canister

Abstract

A fuel system for a vehicle includes a fuel boil-off gas treatment system configured to control fuel boil-off gas generated in a fuel tank, the fuel boil-off gas treatment system including: a gas collection chamber configured to store fuel boil-off gas discharged from a canister through an atmospheric line connected to the canister; an outlet of the gas collection chamber is connected to the purge line through the intake line such that the fuel boil-off gas stored in the gas collection chamber flows into the engine through the intake line and the purge line.

Description

technical field [0001] The present disclosure relates to a fuel system for a vehicle. More particularly, the present disclosure relates to a fuel system for a vehicle that can eliminate a fuel odor generated due to exhaust of fuel boil-off gas from a tank of the vehicle. Background technique [0002] In general, a fuel system for a vehicle includes: a fuel tank configured to store fuel; a fuel pump module configured to discharge fuel stored in the fuel tank to supply fuel to an engine; a fuel filter configured to configured to remove impurities from fuel supplied to the engine; and fuel lines, such as a fuel supply line and a fuel return line, configured to pass fuel therethrough. [0003] The fuel system also includes a fuel vapor treatment system configured to treat and remove fuel vapor (hydrocarbon gas) generated inside the fuel tank. figure 1 is a schematic diagram showing the configuration of a fuel boil-off gas processing system. exist figure 1 1 , reference numer...
