 CAT NOx REDUCTION SYSTEM
The Cat NOx Reduction System captures and cools a small quantity of exhaust gas, then routes it back into the combustion chamber where it drives down combustion temperatures and reduces NOx emissions. The result of more than a decade of Caterpillar engineering research into this technology, the Cat NOx Reduction System is designed to be the most reliable system of its type.
