Cat achieves the required 90-percent reduction in particulate matter and 45-percent reduction of oxides of nitrogen by adding to its ACERT technology series turbochargers (to improve both low- and high-end throttle response), and a suite of NOx reduction technologies to fit various equipment manufacturers’ needs.
