Die Erfindung· betrifft eine VerbesserungThe invention relates to an improvement

der Auspuffeinrichtung für Kraftwagen. Sie bezweckt die störenden Wirkungen der Auspuffgase, insbesondere den schlechten Geruch, möglichst zu beseitigen. Dies geschieht da-the exhaust system for motor vehicles. she aims at the disturbing effects of the exhaust gases, especially the bad smell, to eliminate if possible. This is done because

«iurch. daß die flüssigen un-i festen Jiestan-lteile der Auspuffgase, die die störenden Wirklingen zum großen Teil verursachen, auf elektrostatischem Wege aus dem Gase ausgeschieden werden, wie dies bereits zum Ab-«I by. that the liquid and solid parts of Jiestan the exhaust gases, which cause the disruptive effects to a large extent, are eliminated from the gases by electrostatic means as it has already been

Claims

separating ashes and for precipitating smoke is known. The electrical separator is inserted in the muffler or in the exhaust pipe. The electricity for «he device will by one driven by "the engine DC or AC dynamo machine, the voltage of which is supplied by a voltage converter is increased. For automobiles with electric lighting the light dynamo can be used to operate the electrical separation device will. If the usual DC machines are used for the lighting, it may be advantageous to use the Convert direct current to alternating current using the simple and cheap alternating current transformer to be able to use to increase the voltage. The DC machine for the lighting then only needs with two slip rings to take the alternating current for the electrical separation device to be provided.

An embodiment of the invention is illustrated in the drawing. The engine of the motor vehicle is denoted by ■; «■, with r the exhaust pipe emanating from it, which opens into the muffler α. The muffler α is through a wall τ «. ' with a passage opening 0 for the exhaust gas divided into two chambers, leren rear serves to accommodate the electrical separation device. In the present case, this consists of wires s stretched across the gas flow, which serve as spray electrodes, and of interposed wires £., Which form the counter-electrodes. The wires? are stretched between wires q , which run along the housing and are electrically isolated from the housing by insulators i. The counter electrodes g are attached directly to the housing wall.

The electrode wires can also be arranged in the longitudinal direction of the housing. Instead of simple wires, wire meshes can also be used in a known manner. The housing itself can be used as a counter electrode.

The electricity is supplied by a direct current machine (/ which is coupled to "the motor"; and the lamps p of the motor vehicle Sf) CiSt. This has two slip rings e suitably connected to the armature winding, from which the low-voltage alternating current is fed to the transformer t , in which the voltage is increased to the required level for clic electrical separation device. The transformer supplies the voltage to the spray electrodes of this device via the splitting / through the insulator / and to the counter electrodes via, the line »; and the housing wall of the exhaust pipe.

The impurities deposited on the electrodes are -by the shock- 6; tion of the separator is shaken when driving to the bottom of the housing, from where they can be removed by a trigger. On the fume cupboard, there is expediently, since the excreted constituents are for the most part liquid Xatur, a valve v.

Instead of uniting the separator with the muffler, it can also be used in a special housing. This housing is given a suitable shape, which is as adapted as possible to the available space. The tube shape is particularly simple.
