PURPOSE:To enhance the efficiency of an engine and to reduce NOX in exhaust gas by enabling to suitably mix hydrocarbon liquid which is higher molecular weight than an LPG into an engine which uses as fuel the LPG, and stopping the supply of hydrocarbon during low speed rotation. CONSTITUTION:A conduit controller body 10 which integrally contains a conduit control valve 30, a control valve 20 and an atmospheric air guide 40 in a transmission passage which supplies hydrocarbon liquid to a fuel suction passage to an engine, in whch a mixture gas of LPG and air flows. The body 10 is connected through an adapter 12 to a hydrocarbon liquid tank, and through adapters 13, 25 to a fuel suction passage. The valve 30 controls the depth of a groove 3 by the threadening movement of a threaded rod 30c to alter the sectional area of the conduit. The valve 20 moves a valve rod 20a through a diaphragm 21 by a spring 22 to a closing direction when the suction negative pressure in the fuel suction passage becomes the prescribed pressure or lower, thereby closing the passage 1c. |
