Mack unveils low-NOx engines that meet California standards

Mack Trucks Inc. is the latest manufacturer to announce 2008 engines that meet California’s clean idle standard.

According to Mack, the California Air Resources Board has certified Mack MP7 and MP8 engines. That means they will be allowed to idle beyond the state’s five-minute limit. The Mack MP10 engine is expected to meet the standard when it goes into production later in 2008.

“Customers now have the option to specify ‘Idle Emission Certification – CARB 08’ for Mack MP Series engines,” a Mack press release stated.

CARB requires all 2008 model-year and later engines to have ECMs programmed to shut off the engine after five minutes parked and 15 minutes without the parking brake engaged. Engines certified to emit 30 grams or less per idling hour are exempt from the requirement, however.

Trucks that idle beyond five minutes have been subject to administrative fines since Jan. 1. Previously, the state allowed idling beyond five minutes while truckers were in the sleeper.

“This feature gives Mack drivers the ability to idle their engines as needed, while still emitting extremely low levels of NOx,” said David McKenna, marketing and sales manager for Mack powertrain, according to a company news release. “Our customers know not to idle unnecessarily, but they will be pleased with having this option. And Mack MP engines are designed to be very fuel efficient while idling.”

Mack is owned by the Volvo Group, a Gothenburg, Sweden-based company, which has annual sales of $42 billion.
