A carburetor for vehicles having a gas fuel stay delaying device is provided to more efficiently absorb the heat of an engine coolant and vaporize, prior to the supply to an engine, by forming an additional snail shell in a second preheating chamber defined in the carburetor and delaying the stay of LPG using the snail shell. A carburetor for gas fuel vehicles includes a first coolant circulation space(400) which is provided on the upper end of a lower unit(300) of the carburetor(100) and is connected to a coolant inlet(410) and a coolant outlet. A first preheating chamber(600) connected to a gas fuel inlet(610) is integrally provided on the lower end of the lower unit. A second preheating chamber connected to a gas fuel outlet(620) is provided on the upper end of an upper unit(200), and a second coolant circulation space(400a) communicating with the first coolant circulation space is integrally provided on the lower end of the upper unit. The carburetor includes a snail shell(700) which selects the second preheating chamber and prevents gas fuel from being in direct contact with the interior of the second preheating chamber, thus delaying the stay of the gas fuel. One end of the snail shell is provided around a gas passage(630) so that the gas fuel passing through the gas passage is introduced into the snail shell, and the other end is provided on the inner wall of the second preheating chamber so that the gas fuel passing through the snail shell is discharged to the gas fuel outlet. |
