Comprehensive engine exhaust emissions tests were carried out in a test cell on seven diesel fuels and two retrofitted diesel particulate filters. For each evaluation, the engine was operated over a legislated non-road steady-state test cycle and a real-world transient cycle. The transient cycle was obtained from a recording of a working Load-Haul-Dump vehicle in an underground mine, which was used to replicate real-world emissions in a controlled environment. The emission data thus obtained was used also to assess the effectiveness of current dilution rates used in a typical underground mechanized platinum mine to meet proposed occupational exposure levels.enDiesel engineExhaust emission reductionDiesel particulate filtersSouth African underground minesConference PresentationWattrus, M., Biffi, M., Pretorius, C.
