CARB-READY APU

Cummins has introduced two new ComfortGuard APU models that are compliant with the 2008 California Air Resources Board’s (CARB) stringent idle-reduction regulations that went into effect on January 1. The new regs also require that diesel-powered auxiliary power units have exhaust aftertreatment.

The ComfortGuard will be available with two options to meet these emissions rules: 1) a stand-alone particulate filter, or 2) a Cummins engine installation kit to route the APU’s 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.
