This paper will present emissions durability data from an underground mining vehicle equipped with diesel particulate filter technology, which was followed over 4000 hrs on a Detroit Diesel Series 60 engine. The twin particulate filter system is catalyzed using a base metal formulation on cordierite wall flow monoliths. After the durability accumulation, the recovered filters were individually emissions tested on a Detroit Diesel Series 50 engine over the ISO 8178 test cycle. Performance, maintenance and emissions issues pertaining to base metal catalysts will be discussed.
