CONSTITUTION: A liquefied natural gas supplying system comprises an electronic valve(20), a pressure regulator(4), and a pressue valve(30). The electronic valve is located at the rear of a vaporizer installed in a fuel supply line connected to an injector(5) of an engine. The electronic valve is controlled by an engine ECU(10). The pressure regulator regulates the pressure of the fuel supply line and discharges the excessive gas pressure of LNG to the air at the front of the injector.</p> |
