arbcombo -- Modification of Johnson Matthey CRT Verification
Posted: 16 Nov 2009 14:16:16
Modification of Johnson Matthey CRT Verification. The Air Resources Board verified the Johnson Matthey Continuously Regenerating Technology (CRT) Particulate Filter as a Level 3 Plus passively regenerating diesel emission control system for use with on-road engines model years 1994 through 2006 and certified with particulate matter emissions of 0.1 grams per brake horsepower hour (g/bhp-hr) or less. That verification has since been modified requiring that on-road engines be certified with oxides of nitrogen (NOx) or non-methane hydrocarbons plus NOx emissions greater than 3.2 g/bhp-hr. Specific conditions for which the CRT has been approved may be found in the Executive Order which will be posted within ten days on the ARB website at http://www.arb.ca.gov/diesel/verdev/verdev.htm .
