Cummins Inc. announced the release of Clean Idle Certified on-highway engines at the Technology & Maintenance Council annual meeting in Orlando last month. The engines are designed to meet the new California Air Resources Board (CARB) idle reduction standards by generating less than 30-g/hr. NOx.

According to Cummins, customers can specify a 50-state Clean Idle Certified engine option when ordering or can opt to update existing 2007 engines to meet the 50-state status.

In addition, Cummins introduced two new ComfortGuard APU solutions at the meeting, also aimed at meeting CARB idle-reduction regulations. The products are available with two options to meet the emissions standards: a stand-alone particulate filter on the ComfortGuard APU engine or an engine installation kit to route the ComfortGuard diesel exhaust gas into the particulate filter.
