The invention is embodied in a diesel system for reducing diesel particulate matter (DPM) emissions particularly in underground diesel engine operations, comprising, in combination, a supply of synthetic paraffinic diesel fuel having substantially no sulfur, aromatics and nitrogen content and formulated to greatly reduce DPM levels in the engine exhaust emissions relative to conventional diesel fuels, and other exhaust emissions processing apparatus preferably forming an aqueous filter constructed and arranged to form a water bath for all exhaust gas output from the engine and including in the water bath a preselected significant quantity of a low foaming wetting composition having a high affinity for hydrocarbons. The invention is further embodied in the method of reducing diesel emission contaminants including providing a supply of synthetic diesel fuel having a negligible sulfur, aromatics or nitrogen content, pre-filtering the diesel fuel, and removing DPM from exhaust gases by filtration. |
