    Abstract: PURPOSE: An evaporation gas suppression equipment of a fuel tank of a vehicle is provided to collect hydrocarbon included in evaporation gas and to supply the collected hydrocarbon to the engine by substituting an expansion tube for a canister. CONSTITUTION: An evaporation gas suppression equipment of fuel tank of a vehicle comprises a fuel tank(20), a cut valve(21) opened and shut by pressure of evaporation gas formed in the fuel tank, a separator(23) formed in the middle of a connection line(22) guiding the evaporation gas to a combustion chamber, an expansion tube(30) formed in the middle of the rear connection line of the separator, a check valve(24) formed in front of the expansion tube, a fuzzy control solenoid valve(27) formed in the rear of the expansion tube to control the amount of fuel evaporation gas supplied to the combustion chamber. The separator is formed to return the condensed fuel to the fuel tank, when the fuel evaporation gas is condensed in the middle of the connection line. The volume of the expansion tube is expanded according to the amount and pressure of the fuel evaporation gas flown in and the collected amount of the fuel evaporation gas is increased. Collection and supply of fuel evaporation gas just by the check valve and expansion tube are possible and the cost is reduced.
