An LPI(Liquefied Petroleum Injection) gas injection system and a gas leakage preventing method and a poor start preventing method using the same are provided to reduce the amount of exhaust gas. An LPI gas injection system includes a fuel bombe(2), a gas injector(42), a fuel supply line(6) and a fuel return line(8), a fuel pump(10), a fuel pressure regulator(16), a pressure and temperature sensor(18), a cooling water temperature sensor, and an intake air temperature sensor. The fuel bombe is filled with LPG. The gas injector is mounted on a combustion chamber of an engine. The fuel supply line and the fuel return line connect the fuel bombe to the gas injector. The fuel pump is installed in the fuel bombe to supply the fuel into the gas injector. The fuel pressure regulator, the pressure and temperature sensor, the cooling water temperature sensor and the intake air temperature sensor are arranged in the fuel return line. |
