- Control Of The Air-Fuel Ratio Of Carburetors (AREA)
Abstract
PURPOSE: To obtain proper value of air-fuel ratio in idling revolution by ON-OFF- controlling the bypass air passage and slow air breed of a carburetor by means of one solenoid valve which performs duty control according to the number of revolution.
CONSTITUTION: On the intake passage for the lower stream of the throttle valve 24 of a carburetor 12, a bypass correcting air passage 16 is opened, and to a slow jet 30, an air-fuel ratio correcting air passage 28 for slow air breed is allowed to communicate. At the top ends of both passages 16 and 28, one solenoid valve 26 is mounted which closes and opens to the air. To said solenoid valve 26, the signal of a revolution number detector 22 is input through a correcting circuit 20, and compared with the standard value in the circuit 20, and duty control is performed according to the differential signal, and thus the number of revolution in idling is feedback-controlled.
