Heavy Duty Diesel Engine Requirements

No model year 2005 or 2006 heavy duty diesel engine may be sold, leased, or registered within North Carolina unless it has been certified by the California Air Resources Board as meeting the requirements of Title 13 of the California Code of Regulations, Section 1956.8.

Certification is granted annually by California to individual engine families and is good for one model year. An engine family is a grouping of vehicles or engine models that exhibit similar emission characteristics (e.g., common engine parameters, fuel system, and emission control systems). Within an engine family, there may be one or more evaporative families that are associated with distinct vehicle models.

2005 Heavy Duty Diesel Engines Certified by the Air Resources Board can be found at: http://www.arb.ca.gov/msprog/onroad/cert/mdehdehdv/2005/2005.php.

2006 Heavy Duty Diesel Engines Certified by the Air Resources Board can be found at: http://www.arb.ca.gov/msprog/onroad/cert/mdehdehdv/2006/2006.php.
