PURPOSE: A system for preventing inflow of liquid fuel into an engine in the cold starting of an LNG car is provided such that LNG is vaporized by first and second vaporizers. CONSTITUTION: A system for preventing inflow of liquid fuel into an engine in the cold starting of an LNG car comprises a fuel tank(10), a fuel line(20), first and second vaporizers(30,50), and an engine system(100). The fuel line connects the fuel tank to an engine to supply fuel to the engine. The first vaporizer firstly vaporizes LNG using convection current in the predetermined position of the fuel line. The second vaporizer secondly vaporizes the LNG passing through the first vaporizer using high temperature coolant. The LNG passing through the second vaporizer is delivered to the engine system through a fuel injection device. [Reference numerals] (AA) Engine |
