Abstract

PURPOSE: To improve drive-ability, an emission perperty, fuel cost, etc. by linking three of the control secondary air change-over to a catalyst device, the control of partial relief of secondary air and the control of a fuel quantity regulator by an exhaust-gas component concentration sensor in repsonse to a change of a warming- up condition.
CONSTITUTION: The first controller 34 consists of the first diaphragm device 39 changing-over the first control valve 32 mounted to a joining section of the first secondary air feed passage 29 and the second secondary air feed passage 30. The second controller 35 is composed of the second diaphragm device 43 operating the second control valve 33 partially relieving the first secondary air feed passage 29. The third controller 36 is made up of the first switch 47 controlling the functioning of an actuator 17 of a fuel quantity regulator 18. The fourth controller 37 is formed of the second switch 49 controlling a solenoid 24 of a choke valve 10. A warming-up condition detector 38 relatively controls the driving devices 42, 46, 48, 50 of each controller.
