Abstract

PURPOSE:To hold mixture ratio to constant, by controlling a flow amount of gas fuel with negative pressure in an intake manifold. CONSTITUTION:Liquid fuel in a liquid fuel tank 1 is fed to a carburetor 3 through a feed fuel pump 2, while gas fuel in a gas fuel tank 6 is fed to a nozzle 10, opened to an intake air flow path, through a solenoid valve 7, pressure regulating valve 8 and flow regulating valve 9. The flow regulating valve 9 is constituted by a diaphragm 12, pressed by a spring 11, and a valve 13, operated by this diaphragm 12, and a space 17, partitioned by the diaphragm 12, is communicated to an intake manifold 4 through a pipe 14, further an inlet 15 of the valve 13 is communcated to the pressure regulating valve 8, while an outlet 16 is communicated to the nozzle 10.
