Abstract

A fuel tank venting system for a hybrid vehicle includes a first flow path configured to deliver fuel vaporized from a fuel tank to a canister, a second flow path configured to deliver air used for cooling a high voltage battery to the canister, a first three-way valve disposed on the second flow path and configured to control opening and closing of a first discharge port for releasing pressure of the fuel tank, a second three-way valve disposed on the second flow path and configured to control opening and closing of a second discharge port for flowing the air used for cooling the high voltage battery into the canister or discharging the air used for cooling the high voltage battery outside the vehicle, and a controller configured to control the first three-way valve and the second three-way valve.

Description

technical field [0001] The present disclosure relates to a fuel tank ventilation system for a hybrid vehicle. Background technique [0002] Generally, gasoline is filled into the fuel tank as fuel for the engine of the vehicle, and if the ambient temperature is high or the vapor pressure of the fuel tank increases due to reasons such as steam movement, there is a risk that gasoline evaporated gas will flow to the outside through the gap of the fuel tank . Since gasoline evaporative gas is carcinogenic and harmful to the human body, environmental laws have been enacted in various countries to regulate the outflow of evaporative gas, and actual vehicles employ a system in which a carbon canister is installed to capture evaporative gas to prevent the discharge of evaporative gas. [0003] In a hybrid vehicle, the fuel tank and high voltage battery are used simultaneously. At this time, as the air that has cooled the high-voltage battery is discharged into the vehicle, the int...
