Abstract

A pollution control system for an internal combustion engine comprises a mechanism for separating air from the environment into nitrogen enriched air and oxygen enriched air. The nitrogen enriched air is introduced to an internal combustion engine, thereby reducing engine combustion temperature and concomitantly reducing oxides of nitrogen (NO.sub.x). A mechanism is also provided for introducing oxygen enriched air to the exhaust products of the internal combustion engine, the mixing of the exhaust products with oxygen enriched air minimizes pollution.
