Truck Anti-Idling Technologies

Vehicles of all types run their engines at idle to provide power to accessories. The type and power demand of a vehicle’s accessories are largely dependent on the function it serves. Examples include the refrigeration system for a chilled or frozen transport truck, the in-transit mixing drum of cement truck, and the pump of a tank truck. Class 7 and 8 long-haul trucks, also referred to as tractor trailers, designed for the transport of goods over long distances are generally equipped with a sleeper cabin in which the driver lives while on the road. Typically, these types of trucks idle to provide power for cabin climate control; residential-type AC electricity loads, also referred to as “hotel loads;” and other miscellaneous equipment such as main engine block heaters, main vehicle battery recharging, or utility air compressors in some cases.
