LOUISVILLE, KY – Cummins Inc.'s two new ComfortGuard APU solutions are compliant to meet the 2008 California Air Resources Board’s (CARB) idle reduction regulation. The new CARB idle reduction regulation, which went into effect on Jan. 1, 2008, established more stringent standards to further reduce emissions by limiting the idling of new and in-use diesel-powered trucks.

This new California regulation also requires that diesel-powered Auxiliary Power Units (APU), such as Cummins ComfortGuard, have exhaust aftertreatment. Cummins ComfortGuard will be available with two options to meet these new, more stringent emissions criteria: 1) a stand-alone particulate filter on the ComfortGuard APU, or 2) a Cummins engine installation kit to route the ComfortGuard diesel exhaust gas into the Cummins Particulate Filter. The integrated kit for the ISX engine has been approved by CARB. Both options will be in production by the end of June 2008.

The new ComfortGuard APUs meet all Cummins standards for performance as well as all criteria for compliance with the new CARB regulations.

Cummins ComfortGuard APUs feature a two-cylinder, low-emissions diesel engine and either a regenerative DPF or an exhaust adapter kit for use with 2007 Cummins ISX engines. Equipped with a Cummins alternator, the APU produces 4,000 watts at 120 volts and 60 Hz AC. It also produces up to 40 amps at 12 volts DC for charging the truck’s batteries and powering lights and fans.
