Abstract

PURPOSE:To condense the air-fuel ratio in a wide scope of the suction negative pressure responding to the engine temperature by furnishing a back spring made of a shape memory alloy to a diaphragm to drive a valve which closes and opens an auxiliary fuel passage. CONSTITUTION:At a valve body 10 to open and close an auxiliary fuel passage 5 which is furnished at a carburetter 1, a diaphragm valve 6 is furnished. At the negative pressure chamber 7 of the diaphragm valve 6, a back spring 11 made of a shape memory alloy is arranged. In such a composition, the spring force of the spring 11 is strong when the engine is cooled, and the valve 10 is opened at the lighter load side than after the engine is heated, opening the auxiliary fuel passage. And after the engine is heated, the spring force is weakened and the unnecessary fuel increase is prevented.
