Abstract
PURPOSE: To obtain appropriate control on volume ratio of air to fuel in response to an engine fluctuation, by a proportional control of main fuel system of feed-back type carburetor by means of an air inlet negative pressure and by an on-off control of a slow system using an electromagnetic valve.
CONSTITUTION: In an air-inlet line of engine 1, idling switch 3, and in an exhaust line, O2 sensor 5 and ternary catalyst 6, are provided. Signals from switch 3 and O2 sensor 5, etc. are inputted into control circuit 10 and by compairing these signals with set value, its deflection amounts are outputted. On an auxiliary bleeder of slow system of carburetor, there provided on-off electromagnetic valve 9 for introducing of atmosphere via passage 24, 25 and furthermore, in auxiliary fuel passage of main fuel system, arranged a proportional type controling valve 7, driven by an inlet negative pressure, and negative pressure amount for this control valve 7 is controlled by on-off electromagnetic valve 9. And both electromagnetic valves 9, 9 are electrically connected with circuit 10.
