摘要

PURPOSE: A dual fuel tank of a LNG vehicle is provided to enhance the insulating performance through the decrease of a cross section required for heat transfer by the decrease of a pipe of an auxiliary fuel vessel. CONSTITUTION: A dual fuel tank(100) of a LNG vehicle comprises a main fuel vessel(110) and an auxiliary fuel vessel(120). The main fuel vessel comprises first port assembly(130). The auxiliary fuel vessel comprises second port assembly(140). The first port assembly comprises a supply pipe(131), a fuel filling pipe(132) and a vent pipe(133). The supply pipe is connected to a fuel supply pipe and supplies LNG to the engine. The vent pipe discharges the gas vaporized in the main fuel vessel.
