KIRKLAND, Wash. – Kenworth’s Clean Power no-idle system is fully compliant with California Air Resources Board (CARB) idling regulations which go into effect Jan. 1 for sleeper trucks with 2007 and later model engines.

CARB’s new regulatory measures expand the five minute idling limit for heavy-duty vehicles to include sleeper berth trucks, ending their exemption to idle the engine during periods of sleeper and rest by year’s end.

CARB’s heavy-duty vehicle idling emission reduction program also sets requirements for anti-idling technologies, including auxiliary power units (APUs) and fuel-operated heaters.

Both the idling and emission regulations apply to heavy-duty trucks operating in California, whether or not they are registered in the state.

“Customers operating Kenworth T660s equipped with Kenworth Clean Power can rest comfortably without idling and conform with California’s new, five minute idling limit when it takes effect on January 1, 2008,” said Mike Dozier, Kenworth chief engineer. “Kenworth Clean Power also may enhance fuel economy by as much as 8% for customers with current high idling times.”
