Cummins ComfortGuard APU can meet California emissions limits with a stand-alone DPF or a kit that routes its exhaust through the truck's primary DPF.
LOUISVILLE, Ky. — The Cummins ComfortGuard auxiliary power unit (APU) is now California-compliant, the company announced at the Mid-America Trucking Show this week.
The California Air Resources Board (CARB) requires diesel-fired cab comfort solutions to have exhaust aftertreatment systems such as a diesel particulate filter (DPF). The new rule kicked in Jan. 1, 2008.
Cummins said it has complied with the requirement by offering its ComfortGuard APU with either a stand-alone DPF or an engine installation kit that routes the diesel exhaust gas through the truck’s main DPF. Both options will be in production by the end of June, the company announced.
“Cummins ComfortGuard APUs offer the best solutions for a vast majority of trucks on the road,” said Shawn Wasson, APU business leader for Cummins. “These new 2008 CARB-certified APUs will give drivers cost-effective options to idling when necessary, with increased benefit to the environment.”
The exhaust adapter kit is designed for use with 2007 Cummins ISX engines.
“Cummins is the only manufacturer with experience in the design and production of all the components in an APU diesel engines, diesel exhaust aftertreatment systems, alternators and controls,” explained Wasson. “That experience is critical to designing products that offer superior performance, low maintenance and cost-saving advantages for the trucking industry.”
