THE INVENTION TEACHES A DIESEL FUEL FILTER CONTAINING A SMOKE SUPPRESSANT, AND A METHOD OF SUPPRESSING SMOKE IN EXHAUST FROM A DIESEL ENGINE. THE SMOKE SUPPRESSANT IS ADSORBED ONTO A STRIP (3) OF POLYESTER SPONGE OR MESH. SIX TO EIGHT STRIPS (3) ARE INSERTED IN THE GAPS BETWEEN THE FOLDS OF A PLEAT OF FILTER PAPER (2), EQUI-DISTANTLY AROUND A ROUND CONTAINER OR CANISTER (1), WHICH HOUSES THE FILTER PAPER (2). THE SMOKE SUPPRESSANT IS SLOWLY RELEASED TO A STREAM OF DIESEL FUEL FLOWING THROUGH THE FILTER INTO THE DIESEL ENGINE FOR SUBSEQUENT COMBUSTION. THE ADDITIVE-COATED STRIPS (3) ARE DESIGNED TO LAST THE WORKING LIFE OF A DIESEL FUEL FILTER. THERE ARE SEVERAL EMBODIMENTS OF THE INVENTION, DEPENDING ON THE SIZES OR REQUIREMENTS OF DIESEL ENGINES.
