    Facts about APU’s

    Savings and Benefits

    “The amount of idling varies widely among trucks by season, type of operation, and driver practices. A typical long-haul combination truck can idle between 1,600 and 2,400 hours per year, which would use about 900 and 1,400 gallons of fuel, respectively. Saving fuel annually through idle reduction by installing an APU would remove
    about 9 to 14 metric tons of carbon dioxide, reduce nitrogen oxide and particulate matter emissions, save between $3,600 and $5,500 in fuel costs, and lower engine maintenance costs. A short-haul truck can save 360 gallons per year, saving $1,300 when using an idle reduction technology.” – “Idle Reduction, a Glance at Clean Freight Strategies”. EPA Smartway.
