The Cat NOx Reduction System (NRS) 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.All Cat engines feature innovative air-management systems that optimize airflow and enhance power, efficiency and reliability.These durable injectors enhance responsiveness while controlling soot. Advanced MEUI-C injector platforms deliver increased injection pressures and more precise fuel rates.Delivering better fuel economy with minimized maintenance costs while providing the same great power and response.Minimized impact of emission systems: designed to be transparent to the operator without requiring interaction.

Maximized uptime and reduced cost with world-class support from the Cat dealer network.Every Tier 4 Final/Stage IV and EU Stage V Cat engine is equipped with a combination of proven electronic, fuel, air and aftertreatment components.
