![]() ![]() The most prevalent onboard technology was directfired heaters, which were used by 32% of respondents with sleeper cabs.īattery-powered air conditioners were used by 24% of respondents with sleeper cabs, while auxiliary power units/ generator sets were used by 12% of respondents with sleeper cabs.ĭirect-fired heaters were reported to be the least expensive onboard technology to purchase and to maintain.īattery-powered air conditioners were the next least expensive technology to purchase and maintain, followed by auxiliary power units/generator sets.īased on the reported average capital cost for each type of equipment installed, the study found respondents had already spent nearly $8.8 million on idle reduction technologies.įollowing is an overview of different idle reduction solutions on the market today. These technologies were reported to be used an average of 29 hours per week or 1,508 hours annually. Day cabs were reported to idle an average of 6 hours per week, which equates to 312 hours annually.Ībout 36% of respondents with sleeper cabs used onboard idle reduction technologies, which provide power for heaters, air conditioners, and/or in-cab appliances while eliminating main engine idling. Sleeper cabs were reported to idle an average of 28 hours per week, which equates to 1,456 hours annually. The most extensive study ever on the topic, survey participants provided data on more than 55,000 trucks, allowing researchers to compile a comprehensive profile of idling and the use of idle reduction technologies. of Energy’s Clean Cities Program and the New York State Energy Research and Development Authority, conducted a national survey in 2006 to gather information on the use of idle reduction technologies among trucking fleets. With the growing number of regulatory and financial incentive initiatives aimed at curtailing commercial vehicle idling, the American Transportation Research Institute (ATRI), in partnership with the Dept. ![]() Truck idling also emits more than 11 million tons of carbon dioxide and more than 180,000 tons of nitrogen oxides annually, as well as fine particulate matter and other harmful air toxins. of diesel fuel annually at considerable costs to the trucking industry as a whole. The payback for use of engine idle reduction technology in fuel savings alone can come in as few as six months, depending on the solution used.ĮPA studies indicate long duration truck idling consumes more than 1 billion gals. Unnecessary idling just two hours per day squanders at least $1,040 per year per truck, based on a diesel price of $4/gal. As demands to reduce heavy-duty truck idling increase, fleet executives and owner-operators continue to look for the best idle reduction technologies available.Īccording to the Environmental Protection Agency (EPA), a typical commercial truck can waste a half-gallon of diesel fuel per hour while idling. ![]() Shutting down engines is not only better for the environment and your fuel budget, it’s also the law in most states, and fines for non-compliance can be large-reaching $5,000 plus jail time in some locations. The best way to save fuel and the environment- and avoid costly fines for violating anti-idling laws-is to turn those engines off whenever possible. ![]()
