PURPOSE: A vaporizer of an LPG(Liquefied Petroleum Gas) vehicle is provided to enhance convenience and to improve operating condition by automatically supplying the fuel of a proper amount in the low-speed or idle operation. CONSTITUTION: A vaporizer of an LPG vehicle has a first pressure reducing chamber(22), a second pressure reducing chamber(24), and a main path(3) for supplying fuel to the second pressure reducing chamber from the first pressure reducing chamber. A bypass branch pipe(3a) is diversified from the main path to connect the first pressure reducing chamber with the second pressure reducing chamber. A shut-off valve(25) is installed in the branch pipe to selectively shut off the inside of the branch pipe. An electronic control unit(30) controls the shut-off valve depending on the variable fuel demanding amount of an engine.
