The Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) have reduced the temperature specs for Johnson Matthey's diesel particulate filters (DPF), including the CRT (Continuously Regenerating Technology) and CCRT (Catalyzed CRT) systems.
Revising the exhaust outlet temperature specifications downward means that these DPF units can now be used on “low-temperature applications such as school buses and refuse trucks,” according to Johnson Matthey.
