face each other close to the mouth of the fuel nozzle to achieve an especially balanced combustion process under safe ignition conditions in changing load conditions over the total range of revolutions of the diesel engine it could be of further advantage that the end portion of the combustion chamber is void of any build ins and where the first and second partial exhaust flows mix with perforations provided for the onward flowing of the portions of the main exhaust here a small first partial exhaust enables the preservation of stable igniting conditions in conjunction with continued complete incineration of the exhausts with the remaining co 2 of the successively introduced portions of the partial exhaust flow it does not matter within the boundaries of the invention what kind of a soot filter is used for example the standard ceramic filter come into consideration as well as the so called ceramic swaddle filter where steel pipes with punched holes are wrapped with a ceramic fiber furthermore within this invented method an exhaust turbine could be in series the fuel used for the function of the fuel nozzle can be matched according to the preference of the motor fuel which has been given an advantageous additive to help the incineration process of the burning of the soot the supply of fuel into the fuel nozzle can be regulated according to the engine load from an operating point of view the hotter the engine exhaust in the regeneration area the less fuel injected into the combustion chamber is needed.
