Abstract
A method of regenerating a diesel particulate filter (DPF) may include operating a vehicle including a diesel engine at an idle condition and applying a load to the diesel engine during the idle condition to increase an exhaust temperature of the diesel engine relative to a nominal idle condition. The increased exhaust temperature may regenerate a diesel particulate filter of the diesel engine during the idle condition.
