Studies are described for the development of a combined diesel particulate and NO/sub x/ emissions control system for underground diesel mine vehicles. It is known that methods for reduction of NO/sub x/ tend to increase particulates, unburned hydrocarbons and carbon monoxide emissions. The strategy pursued, therefore, is to attempt to find a compromise combination using exhaust gas recirculation (EGR), for NO/sub x/ control, and a ceramic diesel particulate ''wall'' filter (DPF), together, to make significant reductions of both NO/sub x/ and particulate with minimum increases in CO and hydrocarbon emissions. The application of Corning DPFs, of EGR, and of DPFs and EGR in combination are made on heavy-duty diesel engines of a type typically used on load-haul-dump vehicles in mining operations. Steady-state tests and simulated mine duty cycle tests are made using engine dynamometer facilities. The ability of the DPF's to auto-regenerate by burn-off of the collected particulate during regular engine operation is studied by evaluation of duty cycle exhaust temperature profiles and by simulated duty cycle runs.
