Abstract

PURPOSE: A secondary air feeding pipe is connected with the exhaust pipe arranged between the air-fuel ratio detector and the catalytic converter, and on said feeding pipe, a secondary air control valve is arranged, and in deceleration the secondary air is blown out into the exhaust pipe, and CO and HC in the exhuast gas is treated effectively.
