Mack Engines Certified To California Clean Idle Rules

Posted on April 30, 2008

Mack announced that its MP7 and MP8 engines have been certified to meet California’s 2008 clean idle standards, which are intended to limit emissions of nitrogen oxides (NOx) while idling. The certification means Mack customers with compliant engines will not have to shut down their engines after five minutes of idling as otherwise required by California regulations which took effect earlier this year.

Customers now have the option to specify “Idle Emission Certification – CARB 08” for Mack MP Series engines built after January 1, 2008. This feature means the truck’s engine has been certified to meet the 30 gram/hour NOx limit. A CARB-required decal affixed to its hood identifies the truck as meeting the regulation. The new Mack MP10 engine will also be able to meet this standard when it goes into production later this year, Mack said.
