PURPOSE: An LNG fuel supply system for a low pressure heterogeneity fuel engine is provided to simplify a system configuration efficiently for supplying an engine fuel by removing a heavier hydrocarbon component contained in a liquefied natural gas and vaporizing the liquefied natural gas. CONSTITUTION: An LNG fuel supply system for a low pressure heterogeneity fuel engine comprises a fuel tank (100), a fuel transport unit (200), a low temperature heat exchanger (300), a fuel supply unit (400), and an exhaust line (500). The fuel tank stores a liquefied natural gas of a high pressure. The fuel transport unit guides the liquefied natural gas inside the fuel tank to an outside. The low temperature heat exchanger stores the liquefied natural gas transported from the fuel transport unit, and separates into a gaseous fuel and a liquid fuel at the same time. The low temperature heat exchanger comprises a refrigerant flow pipe (310), and an organic refrigerant and heating element (320). The fuel supply unit supplies a gaseous fuel vaporized from the low temperature heat exchanger into a low pressure heterogeneity fuel engine. The exhaust line is installed at a lower part of the low temperature heat exchanger. |
