Abstract
PURPOSE: To achieve a proper air fuel ratio during idle running by regulating a bypass air on the basis of a signal of a revolutional speed sensor of an engine, and a carbureter air bleed quantity on the basis of a signal of an O2 sensor of an exhaust system.
CONSTITUTION: A secondary air bypass 16 containing a primary control valve 17 opens into a suction port 2 downstream a throttle valve 3g of a carbureter 3. As the primary valve 17 is controlled to be opened or closed once an idle running speed control circuit 19 receives a signal of a revolutional speed sensor 18a of an engine 1, the valve supplies an amount of secondary air for revolutional speed requirements. Secondary control valves 14, 15 respectively provided in main and slow auxiliary air bleed passage 9, 10 of the carbureter 3 are controlled by an air fuel ratio control circuit 21 which receives a signal of an O2 sensor 20 so that the air fuel ratio may be kept close to a theoretical air fuel ratio.
