The Air Resources Board has verified the Johnson Matthey reformulated CRT™ Particulate Filter system for specific 1994 through 2006 model year diesel engines used in on-road applications. All of these engines are four-stroke, turbocharged, and were certified in California to the 0.1 gram per brake horsepower-hour (g/bhp-hr) particulate matter (PM) emission standard when new. The reformulated CRT™ Particulate Filter system employs a catalyst and a wall-flow diesel particulate filter with a back pressure monitor to achieve an 85 percent reduction in particulate matter emissions, qualifying it for Level 3 “Plus” verification. Specific engine families and conditions for which the reformulated CRT ™ Particulate Filter system has been approved may be found in the Executive Order and attachment below.
