Abstract

PURPOSE: To facilitate air/fuel ratio control in exhaust gas by the combined use of a device for recycling exhaust gas to an intake system to control the combustion ratio of the gas mixture and a device for reducing the generation of NOx to reduce the ratio of purifying NOx in a tertiary catalyst device.
