Abstract
Diesel engine exhaust filter system for off-road vehicles. The system has a trap device and controlling mechanism on the vehicle. An electrical power source and a combustion air source are off-board. The controlling mechanism monitors backpressure to determine when regeneration is required. The vehicle is parked at a regeneration station for connection to the air source and power source for regeneration, which is then controlled by the controlling mechanism on-board.
