Optimize performance

Each Cat engine compliant with Tier 4 Final/Stage V standard is equipped with a set of proven components for electronic, fuel, air, and after-treatment circuits. Optimization of availability and cost reduction, with world-class support offered by the Cat dealer network. Reduction of the impact of emission systems: designed to be completely transparent to the driver without requiring intervention. Superior fuel savings and reduced maintenance costs while providing the same power and responsiveness. Advanced mechanically controlled electronic unit injectors (MEUI-C) provide higher injection pressures and improve injection rate accuracy. These durable injectors enhance responsiveness while controlling soot levels. All Cat engines are equipped with innovative air management systems that optimize air flow for more power, efficiency, and reliability. The Cat Nitrogen Oxide Reduction System (NRS) captures and cools a small amount of exhaust gas, then redirects it into the combustion chamber to lower combustion temperatures and NOx emissions. Cat engines are equipped with a Selective Catalytic Reduction (SCR) system that injects Diesel Exhaust Fluid (DEF) into the exhaust stream to reduce NOx emissions. DEF is a blended solution composed of 32.5% high-purity chemical urea and 67.5% deionized water.
