Abstract
PURPOSE: To purify exhaust as well as to stabilize idling by both using an exhaust recirculating unit and a secondary air inlet device.
CONSTITUTION: An air intake port 11 is conducted to an exhaust port 12 by an exhaust recirculating passage 13, an exhaust recirculating valve 14 is arranged at the intermediate part of the recirculating passage 13. The exhaust recirculating valve 14 shuts off the exhaust recirculating passage 13 at the time of idling. The intermediate part on the side of the exhaust port 12 rather than the fitting part of the exhaust recirculating valve 14 has a secondary air inlet valve 16 installed, the secondary air inlet valve is constituted to be opened only at the time of idling.
