Abstract

PURPOSE: To constantly control air-to-fuel ratio by providing a control valve so as to have the sum of the sectional area of the flow passage at the atmospheric opening port and that of the flow passage at the fuel gas inlet port constantly stabilized on the fuel passage.
CONSTITUTION: A fuel passage 10 is branched into an air passage 11 and a fuel passage 38, each orifice 31, 32 is installed at the branched place, and a drum-type valve 33 is inserted in this passage. The shape of the drum-type valve 33 is made in such a way that the constant stabilization may cover the sum of the air flow passage sectional area Ac which is formed by the air orifice 31 and the drum-type valve 33 and the sectional area A0 which is formed by the fuel orifice 32 and the drum-type valve33. Said drum-type valve 33 is fixed onto a control valve 30 which is controlled by O2 in the exhaust with use of a sensor 15 in an exhaust pipe 19. Said constitution makes it possible to control constantly the air-to-fuel cost regardless of the drive situation
