Abstract
PURPOSE: To set controllably air fuel ratio in a carbureter to a predetermined value accurately by detecting warming-up condition of an engine and sending control signal computed by a control circuit to an actuator provided in an air or fuel system of the carbureter.
CONSTITUTION: A control circuit 400, upon receiving signal of a cooling water temperature sensor 104, sends control signal corresponding to water temperature value at that time to an actuator 300. Then a movement shaft 301 is displaced and controlling valves 303, 304 control the opening area to control air bleeding amount sent to main and low speed systems of a carbureter 200 through air bleed paths 204, 205 and vary fuel amount from a main fuel nozzle 203 and an injection port of the low speed fuel system for providing proper mixture to an engine body 100. When a cooling water temperature sensor 104 senses a temperature corresponding to warming- up running of the engine the control circuit 400 controls the opening area of air bleed to maintain air fuel ratio in the carburetor 200 at the target air fuel ratio.
