Abstract

PURPOSE: To make a supply of secondary air correctly operated to the exhaust pipe, by operating the supply of the secondary air deriving from a working of at least one of the speed reduction detector and the idling detector.
CONSTITUTION: Output of the second AND circuit AND2 is of high potential when both opened a speed reduction detecting switch 24a and an idling detecting switch 7b, and of low potential when closed one of the both. Consequently, even in a case with the first throttle valve 15 opening degree not reaching an idling opening degree and an idling detector 7 not working, when provided a speed reduction to increase rapidly the negative pressure of an air intake pipe 25 to an extent enough for operating a speed reduction detector 24, a three-way solenoid valve 12 is actuated to supply the secondary air to an exhaust pipe 2.
