ABSTRACT:
An arrangement for exhaust gas purification is such that a plurality of valve openings communicate the suction or intake tube within the cylinder with a recirculation pipe for recirculating the exhaust gas into the suction tube, and each valve opening is controlled to open or close by means of a valve which is regulated in response to various signals derived from the internal combustion engine and emitted as signals from a computer so as to thereby adjust the flow rate of the exhaust gas being recirculated and to purify the same.
