  • Process for reducing the soot content of diesel engine exhaust gases and device for implementing it
    Patent number: 6158397
    Abstract: In 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.degree..+-.5.degree. before top dead center and the fluid containing the peroxide compound is fed in the range 5.degree. to 30.degree. 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.
