Cummins Releases CARB-Compliant APU

Diesel engine maker Cummins Inc. Wednesday unveiled two new auxiliary power unit systems that are compliant with new California Air Resources Board idle-reduction regulations.

Cummins released the two ComfortGuard units at the at the Mid-America Trucking Show in Louisville, Ky.

The new CARB idle reduction regulation, which went into effect on Jan. 1, established more stringent standards to further reduce emissions by limiting the idling of new and in-use diesel-powered trucks. The standards require that diesel-powered APUs have exhaust aftertreatment.

Cummins said its ComfortGuard will be available with two options to meet the standard —a stand-alone particulate filter on the ComfortGuard APU or an engine installation kit to route the ComfortGuard diesel exhaust gas into a particulate filter on a Cummins engine.

“Cummins ComfortGuard APUs offer the best solutions for a vast majority of trucks on the road,” said Shawn Wasson, Cummins’ APU business leader. “These new 2008 CARB-certified APUs will give drivers cost-effective options to idling when necessary, with increased benefit to the environment.”
