Abstract
PURPOSE: To prevent the non-operation of a control valve by non-decomposed fuel, by mounting an air circuit, to which an air flow rate control valve is arranged, and a fuel mixed gas circuit in parallel with an upper stream of an improving instrument.
CONSTITUTION: An air circuit provided with a flow rate control valve 4 for passing a large portion of sucked air and a fuel mixed gas circuit for producing mixed gas between one portion a1 of sucked air and fuel f after the one portion a1 passes through a passage 17 opening to a Venturi 11 are mounted in parallel between a carbureter 1 and an improving instrument 2 for feeding mixed gas to an engine 5. The flow rate control valve 4 adjusts the opening of the valve in response to differential pressure P1, and works so as to constantly keep the quantity of air. The flow rate control valve 4 accurately acts without being affected by non-decomposed hydrocarbon and condensed water or soot, etc. formed at the improving insturment 2 because it is located at an upper stream of the improving instrument 2, and can also prevent the effects to atomized fuel bacause fuel does not pass.
