Abstract
Systems and methods for using a diesel particulate filter (DPF) heater as a load bank to maintain a minimum exhaust temperature for a diesel oxidation catalyst (DOC) paired with a prime mover are provided. The system includes a prime mover coupled with a generator, a compressor powered by the prime mover, a DOC disposed downstream from the prime mover, and a controller. The prime mover is separate from another prime mover used for operating a vehicle. The controller is configured to determine a load of the generator, to determine a load of the compressor, to determine a load of the prime mover based on the determined load of the generator and the determined load the compressor, and to control the load of the prime mover to maintain a minimum exhaust temperature for the DOC.
