Abstract

PURPOSE: To enhance fuel-jet responding obility by setting passage section variable actuator on bypass air passage where air-flow detector controlling air fuel ratio is set so as to organize properly responding variation work in accordance with operational condition.
CONSTITUTION: Fuel jet volume ex unillustrated fuel jet valve is made to be controlled according to the passing air volume by setting bypass air passage 4 with air flow volume detector 5 on such roudabout positon from air-supply drum 1. Diaphragm valve 10 which functions as actuator is set on air-passage 4. The valve 10 is firmly set with diaphragm 9 and holds the valve element 8 which is fixed to the diaphragm 9 and can change sectional area of the air passage 4. Thus it becomes now capable to determine the sectional area in accordance with the suction negative pressure to affect the negative pressure room 11.
