Mack MP7, MP8 engines certified to meet California emissions standards

Mack customers now have the option to specify their Mack MP7 and MP8 engines to meet 2008 California emissions regulations for idling, using the “Idle Emission Certification – CARB 08” feature. This allows drivers to idle their engines, when necessary, beyond the five-minute limit for engines not meeting the regulations.

LEHIGH VALLEY, Pa. — Mack MP7 and MP8 engines have been certified to meet California’s 2008 criteria to limit emissions of nitrogen oxides (NOx) while idling, the company announced today.

This 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, according to David McKenna, Mack powertrain sales and marketing manager. 

The California Air Resources Board requires trucks to stop idling after no more than five minutes, under most circumstances.  However, trucks with engines which emit 30 grams or less per hour of NOx are not required to shut down and can continue to idle, which can be necessary to provide a comfortable environment for resting drivers in hot or cold weather.

McKenna said several other states intend to pursue adoption of California's idle regulations in the near future.

Customers now have the option to specify “Idle Emission Certification – CARB 08” for Mack MP Series engines built after Jan. 1, 2008, meaning that the truck’s engine has been certified to meet the 30 gram/hour NOx limit, McKenna said.  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 customers can order this feature from their dealers now.

“This feature gives Mack drivers the ability to idle their engines as needed, while still emitting extremely low levels of NOx,” McKenna said.  “Our customers know not to idle unnecessarily, but they will be pleased with having this option for those times when idling is necessary.  And Mack MP engines are designed to be very fuel efficient while idling.”
