摘要： A pilot burner for a device for burning off solid particles, especially soot particles, in the exhaust gas of internal combustion engines has a hollow-cylindrical mixture preparation chamber receiving a glow element and extending eccentrically thereto a hollow-cylindrical glow plug receiving chamber. The two chambers communicate with one another via an opening formed by piercing the chamber walls. A fuel inflow line discharges in the receiving chamber and an air supply line discharges into the preparation chamber. To improve the mixture preparation and largely avoid carbonization of the glow plug, the air supply line discharges into two inflow openings having a tangential direction; one inflow opening is located opposite the opening between the two chambers, and the other inflow opening is located near the end face of the preparation chamber having a mixture outlet opening. In obth inflow openings, the combustion air is introduced in the same direction.

摘要： A device for removing solid particles, in particular soot particles, from the exhaust gas of internal combustion engines includes a centrifugal separator or cyclone 11 to separate the untreated gas flow 10 into coaxially removed pure gas flow 23 and a particle-enriched carrier gas flow 24 and includes a combustion device 12 for burning the solid particles carried in the carrier gas flow. In order to reduce the manufacturing costs and to obtain a compact, small-volume assembly the combustion housing 16 of the combustion device 12 is integrated in the collecting piece 133 of the cyclone housing 13 such that an annular channel 18 is left between the combustion hosuing 16 and the collecting piece 133 through which a carrier gas flow is passed so as to enter the combustion housing 16 at the end of the latter facing away from the interior of the cyclone housing 13, to pass through a filter 27 heated up above combustion temperature of the solid particles and to finally enter into the vortex core of the cyclone and be removed together with pure gas flow 23. The free end of the collecting piece is closed so as to prevent carrier gas from escaping.

摘要： An apparatus for burning solid particles, in particular soot particles, in the exhaust gas of internal combustion engines having a combustion chamber and an ignition burner connected coaxially through an overflow opening. The combustion chamber includes an annular cup portion forming a hot combustion chamber that is open toward the overflow opening, and downstream of this hot combustion chamber has a plurality of labyrinthine annular conduits toward which a plunger tube extends centrally toward the combustion chamber, through which tube a flow of exhaust gas carrying the soot particles is directed into the hot combustion chamber. The flow of exhaust gas having the soot particles emerges into the hot combustion chamber through radial outlets transversely to the direction of extension of the ignition flame that is propagating through the overflow opening. The soot particles that are supplied are for the most part burned in the hot combustion chamber, and the remainder is burned in the labyrinthine conduits. The exhaust gas from the burner is carried away in a counter current to the exhaust gas laden with soot particles that is delivered to the plunger tube.

摘要： An apparatus for removing solid particles, especially soot particles, from the exhaust gases of an internal combustion engine includes a separator that divides the flow of exhaust gases into a largely particle-free primary flow and a particle-enriched secondary flow. The secondary flow is delivered to a disposal device, which has a combustion chamber and a pilot burner for producing a flame that burns off the solid particles. To improve the efficiency of the apparatus by reducing the heating output required, a filter is provided in the combustion chamber, which divides the combustion chamber into a filter pre-chamber and after-chamber. The burnoff flame of the pilot burner burns into the filter pre-chamber, and the burnoff gases are removed via an outlet opening disposed in the filter after-chamber. The secondary exhaust gas flow is delivered to the filter pre-chamber with a tangential inflow direction.

摘要： An apparatus for the burning of solid particles, especially soot particles, separated from the exhaust gas from internal combustion engines has a rotationally symmetrical combustion chamber which coaxially adjoins an ignition burner connected with it by a flame transfer orifice. Fuel and air are metered to the ignition burner through an additional-air line and a fuel line and, as a prepared mixture, they are ignited in the ignition burner and enter the combustion chamber through a flame transfer orifice. In the combustion chamber an exhaust gas partial stream enriched with the solid particles is introduced, and, after the solid particles have been consumed together with the additional air put into the combustion chamber, the exhaust gas is then discharged again as cleaned exhaust together with the remaining combustion products through an outlet tube.

摘要： A soot reservoir for an exhaust gas scrubbing system for an internal combustion engine has a housing, having an inlet for introducing a soot-laden carrier flow diverted from the exhaust gas flow and an outlet for the escape of the scrubbed carrier flow, a soot filter disposed between the inlet and outlet for retaining soot particles, and a removable collecting container for receiving the trapped soot. To attain a large storage capacity of the collecting container, a number of compacting balls are placed loosely in it. Hopping and rolling movements of the balls caused by the motion of the vehicle driven by the engine produce a considerable increase in the settled apparent density of the soot deposited in the collecting container. With the same collecting container volume, about 10 times as much soot can be held, when compared with conventional soot reservoirs.

摘要： A method is proposed for operating an internal combustion engine with decomposition gas generated by gasifying methanol into hydrogen and carbon monoxide in a gasification reactor. The enthalpy necessary for gasifying the methanol is obtained from the heat of the exhaust gas of the engine. To attain high efficiency and high power, the decomposition gas is injected at high pressure directly into the combustion chamber of the engine.
