| Abstract | A silver-based catalyst was loaded on a commercial ceramic wall-flow filter to produce a prototype catalyzed diesel particulate filter (CDPF). The effectiveness of the prototype CDPF for soot removal
from the engine exhaust was quantified by the balance point temperature (BPT) during the engine test using a heavy-duty mining diesel engine. The determination of the CDPF balance point temperature revealed its high passive regeneration performance.
Emission tests using a medium-duty mining diesel engine demonstrated that the catalyst coating of the CDPF assisted CO and total hydrocarbon (THC) combustion as well as NO2 reduction within a wide temperature range. The average effectiveness of the
particulate matter (PM) mass removal was found to be greater than 85% while keeping the back pressure within the application requirements for the tested engine. The engine test results showed the potential for the lower cost, silver-based, prototype
CDPF to oxidize PM effectively during normal operation conditions. Further, the improvement it provides in passive regeneration would lower fuel consumption and related CO2 emissions by avoiding active regeneration cycles or decreasing their
frequency. |

A silver-based catalyst was loaded on a commercial ceramic wall-flow filter to produce a prototype catalyzed diesel particulate filter (CDPF). The
effectiveness of the prototype CDPF for soot removal from the diesel exhaust was quantified by the balance point temperature (BPT) during the engine test using a heavy-duty mining diesel engine. The BPT determination of the CDPF revealed its enhanced
passive regeneration performance. Emission tests using a medium-duty mining diesel engine demonstrated that the catalyst coating of the CDPF assisted CO and total hydrocarbons combustion as well as NO2 reduction within a wide temperature range. The
average effectiveness of the particulate matter (PM) mass removal was found to be greater than 85% while keeping the back pressure within the application requirements for the tested engine. The engine test results showed the potential for the lower
cost silver-based prototype CDPF to oxidize PM from the exhaust effectively during normal operation conditions. Further, the improvement it provides in passive regeneration would lower fuel consumption and related CO2 emissions by avoiding active
