Audubon, PA —The US EPA has set extremely low emission limits for Tier 4 non-road diesel engines. To meet the requirements of the EPA’s New Source Performance Standards, new engines will come from the factory with low NOx, PM, CO, and HC emissions. For existing engines, Johnson Matthey introduces a Tier 4 solution with its compact and efficient integrated SCRT® (Selective Continuously Regenerating Technology) system combining its CRT® diesel particulate filter (DPF) and SCR technology making it the best available retrofit technology on the market today.
