Truck HVAC System drives engine accessories electrically

MorElectric System provides electrically powered heating, ventilating, and air-conditioning system, allowing all HVAC components to be removed from engine compartment. Electric power comes from 7,300 W generator that replaces alternator. When coupled with Auxiliary Power Unit, system provides driver with comfortable cab environment when main engine is off. Using Shore Power, truck is plugged into pedestal at truck stop, providing low emission idling solution.

Recent Caterpillar and DOE Tests Confirm Savings

The focus on the noise and emissions effects of idling vehicles continues to grow in many states and communities, drawing even more attention to the economic and environmental issues related to wasteful, diesel engine idling. Studies indicate the average U.S. long haul truck engine idles over 1,800 hours annually. At an average fuel consumption of 0.9 gallons per hour, this translates to the fact that more than a billion dollars of diesel fuel is consumed each year simply to provide the driver with a comfortable cab during required rest periods. Now Caterpillar offers an alternative to idling, known as the MorElectric System.

Recently, at one of the trucking industry's largest conferences, the Technology & Maintenance Council (TMC), the US Department of Energy's (DOE) Advanced Vehicle Testing Activity and Caterpillar reviewed some of the early results from tests completed on five Cox Transfer trucks under a DOE Idling Reduction Demonstration Program overseen by DOE's National Renewable Energy Laboratory and managed by DOE's National Energy Technology Laboratory. Ongoing testing of Caterpillar's MorElectric Technology will continue through 2005 on fleets from Cox Transfer, Schneider National, Werner Enterprises, and others, as part of DOE's Office of FreedomCAR and Vehicle Technology and New York State sponsored technology demonstration programs.
