Abstract:
PCT No. PCT/EP97/02253 Sec. 371 Date Jun. 28, 1999 Sec. 102(e) Date Jun. 28, 1999 PCT Filed May 2, 1997 PCT Pub. No. WO97/42405 PCT Pub. Date Nov. 13, 1997In order to reduce the soot content of a diesel engine's exhaust gas, a fluid containing a peroxide compound, preferably an aqueous hydrogen peroxide solution, is fed into the combustion chamber after the start of the injection and combustion of the fuel, preferably following the combustion phase. The diesel fuel is preferably injected in the range 10 DEG +/-5 DEG before top dead center and the fluid containing the peroxide compound is fed in the range 5 DEG to 30 DEG after top dead center. Use may be made for the alternate supply of diesel fuel and hydrogen peroxide of a shared injection nozzle (FIG. 1) which supplies one or other of the media depending on the pressure of the diesel fuel and hydrogen peroxide solution supplied.
