Abstract

PURPOSE:To improve the heat efficiency by performing the fuel supply in a low speed region by a primary fuel supply system constructed in accordance with the low-speed region, and performing the fuel supply in middle and high regions by the primary fuel supply system and a secondary fuel supply system having a variable venturi tube. CONSTITUTION:The primary fuel supply system is provided with a small diameter suction passage 11 disposed in a main structure 9, a primary venturi tube 12 formed in the intermediate of the suction passge 11 and having an invariable sectional area, and a primary throttle valve 13 positioned at the downstream side of the primary venturi tube 12 and loaded within the suction passage 11. The secondary fuel supply system comprises a suction passage 30 provided in the main structure 9, a variable venturi tube 31 provided at the intermediate of the suction passage 30, and a secondary throttle valve 32 disposed at the downstream of the variable venturi tube 31. The secondary throttle valve 32 is controlled of its opening degree by a link mechanism connected to the primary throttle valve 13.
