Abstract
A compression ignition type engine comprising an NO.sub.x arranged in its exhaust passage. This NO.sub.x absorbent absorbs NO.sub.x when the air-fuel ratio of the inflowing exhaust gas is lean and releases the absorbed NO.sub.x when the air-fuel ratio of the exhaust gas is rich. When NO.sub.x should be released from the NO.sub.x absorbent, the mean value of the air-fuel ratio in the combustion chamber is changed from lean to rich. At least at this time, use is made of fuel containing oxygen as the injected fuel.
