Abstract
The U.S. Bureau of Mines (USBM) and Diesel Controls Limited are evaluating a new diesel emission control system on an underground mine vehicle. The system is a catalyzed ceramic wall-flow diesel particulate filter (CDPF) combined with an oxidation catalytic converter (OCC). It is the first installation in the U.S. of a CDPF on a mining vehicle with a turbocharged engine at a high altitude mine, and the first installation of both a CDPF and an OCC on a mine vehicle.This paper describes the design and installation of the system on the load-haul-dump (LHD) vehicle. The results of screening tests conducted by the USBM are also given. The screening tests were conducted to determine if the device's particulate collection efficiency, regeneration temperature, and effect on gaseous hydrocarbon (HC) and carbon monoxide (CO) emissions changed over the period it was being used.The system was removed from the LHD and evaluated in the laboratory after operating for 308 and 1200 hours. After 308 hours of operation, laboratory testing revealed its particulate collection efficiency varied from 41.0 to 93.5 percent, depending on engine operating conditions. Its regeneration temperature was about 415\mDC. It reduced HC emissions by up to 97.6 percent, and CO by up to 95.0 percent. When tested in the laboratory after operating for 1200 hours on the vehicle, no significant change in performance was observed.
