Definitions
- the invention relates to a device for cleaning the exhaust gas Internal combustion engine according to the preamble of claim 1.
- Internal combustion engine is preferably a gasoline engine, in particular around a diesel engine.
- the exhaust gases from an internal combustion engine contain pollutants, in particular C02, HC, N0x and S0x, with mainly carbon-containing particles such as soot particles occur in the exhaust gas, which is due to incomplete combustion, especially of diesel internal combustion engines, arise.
- the invention has for its object the effectiveness of reducing the pollutants to further improve the device.
- the invention is based on the knowledge that the addition of ozone to the exhaust gas Can effect or at least support exhaust gas aftertreatment. Because ozone is very is unstable, it reacts almost immediately and completely with the exhaust gas components, so that ozone slip is not to be expected.
- an ozone source is provided which releases ozone to the exhaust gas in the exhaust pipe.
- the Ozone source is at a delivery point that is at such a distance from the rear end of the exhaust pipe is arranged that the afterburning in the Exhaust pipe at the required post-combustion temperature and - below Taking into account the exhaust gas speed - in the required Post-combustion time can take place before the exhaust gas leaves the exhaust pipe. So hydrocarbons are attacked even at low ozone concentrations broken down into smaller fragments and oxidized.
- the device according to the invention not only enables oxidation, especially of CO and hydrocarbons, but also of S02 and NO as By-product, especially at low temperatures and in Starting area.
- the device according to the invention is also suitable for NO2 production high efficiency for CRT systems, especially at low temperatures.
- On CRT system consists of a particle filter and an upstream one Oxidation catalyst that oxidizes NO to NO2, which is a filter regeneration in particular continuously supported.
- a catalyst and / or Place the gas mixer in the exhaust pipe In order to improve the effectiveness of the ozone addition, it is advantageous in Flow direction behind the ozone delivery point, a catalyst and / or Place the gas mixer in the exhaust pipe.
- the ozone can, depending on Concentration and addition conditions to replace the catalyst function, being a high ozone concentration is advantageous, or supplement, especially on one Expand or support the work area at low temperatures, especially at the partial oxidation of hydrocarbons.
- the ozone can be generated either by means of an ozone source pure oxygen, which should be carried along, or by means of an ozone generator will be produced.
- the ozone source or the ozone generator on or in the is particularly advantageous Exhaust line or on or in a supply line for supply air or fresh air or Arrange secondary air or recirculated exhaust gas.
- Exhaust pipes With an arrangement on or in the Exhaust pipes are supply paths for the outside of the exhaust pipe Avoided ozone.
- the ozone source or the ozone generator is arranged at a distance from the exhaust pipe. In Both cases result in better distribution and mixing of the ozone in the exhaust gas reached. If there is a supply line, it can be used to promote the a gas pump can be provided in the feed line.
- the device according to the invention is characterized by a simple and also safe design and function, whereby it can be converted into a Integrate exhaust system or combine with it.
- An automatic and good mixing of the ozone with the exhaust gas is achieved, if the delivery point is an upstream distance from the catalyst and / or gas mixer.
- the feed line is at an upstream distance from the Catalyst and / or gas mixer opens into the exhaust pipe, will also be a good one Mixing in the exhaust gas achieved automatically due to the exhaust gas flow.
- the ozone generator prefferably has an oxygen ion conductor to be provided so that the oxygen concentration in the ozone generator increases becomes what improves the efficiency of the device.
- ozone generators of different designs can be used and function are used, which are characterized by performance, a safe function and distinguish an advantageous arrangement and a small design and stand out in simply on or in an agas line or on or in an in the exhaust line Have the opening supply line integrated.
- the ozone generator can e.g. by a UV lamp, by a microwave generator or an electric one Spark discharge path are formed.
- the exhaust system is in the form of an exhaust line 2 an internal combustion engine 3 arranged.
- the catalyst 5 and the gas mixer 6 are of conventional construction and each arranged in a housing 5a between pipe sections 2a, 2b, which form the exhaust pipe 2 in front of and behind the housing 5a.
- the catalyst 5 and the Gas mixers 6 form an exhaust gas treatment unit 6a.
- An ozone generator 7 is provided which continuously or intermittently applies ozone emits the exhaust gas and that in a flow direction 4 before Catalyst 5 and / or gas mixer 6 located delivery point 8, in particular has a distance b from the treatment unit 6a.
- the ozone generator 7 is from the exhaust pipe 2 spaced and thus arranged outside of this, being by a Feed line 9 is connected to the exhaust line 2.
- the ozone generator 7 forms the ozone from fresh air or oxygen supplied.
- the ozone generator 7 can be assigned to a pump, not shown in FIG. 1, which pumps the ozone if necessary with the supply air 11 to the exhaust pipe 2.
- the ozone generator 7 can have a display device 12 which has the function or indicates the amount of ozone supplied.
- FIGS. 2 to 4 show possible embodiments of the Ozone generator.
- the Oxygen concentration uses an oxygen ion conductor 14 on the outside 14a is supplied with fresh air or exhaust gas by means of a pipe 15.
- the Oxygen ion conductor 14 is the oxygen of the fresh air or the exhaust gas via the Inside 14 b of the ion conductor 14 transported into a chamber 16, so that it is there a high oxygen concentration.
- a potential is applied to the ion conductor 14 by means of electrical leads 17a, 17b placed, which causes the oxygen transport.
- the chamber 16 is through a Housing 18 formed.
- a gas pump 19 in one Gas passage 21 arranged, by means of which the ozone from the Chamber 16 is pumped into the feed line 9 or into the exhaust system 1.
- the oxygen ion conductor 14 can be an ZrO2 or act on another oxygen ion conductor with pump voltage.
- FIG. 2 to 4 each show a special embodiment for a Ozone generator 7, the ozone generator 7 according to FIG. 2 by an infrared lamp 7a, 3 by a microwave generator 7b and FIG. 4 by a electric spark discharge gap 7c is formed.
- the oxygen ion conductor 14 and the pump 19 can be dispensed with, such as this is shown in FIG. 5.
- the ozone generator 7 or 7a, 7b, 7c is directly in arranged the exhaust pipe 2, each with a UV lamp 7a, for example Microwave emitters 7b and a spark gap 7c are shown.
- a UV lamp 7a for example Microwave emitters 7b and a spark gap 7c are shown.
- a small size Furthermore, the supply route for the ozone is omitted.
- the exhaust gas flows from left to right in FIG. 1 through the exhaust pipe 2.
- the ozone reaches into the exhaust gas stream into which it is distributed and mixed, e.g. automatically due to the Flow and the flow path b between the point 8 and the catalyst 5.
- the invention is based on the finding that the addition of ozone to the exhaust gas Promotes oxidation of pollutants.
- the oxidation performance of the ozone is determined according to the ratio in which it is added to the exhaust gas. With the exhaust gas The ozone thus preferably reaches the gas mixer 6 and / or Catalyst 5, whereby the oxidation can take place.
- the generation or supply of the ozone can be carried out continuously or be carried out discontinuously.
- the latter can be done by a not shown Control device, in particular by the existing electronic control device, by switching on and off, e.g. by switching on and off each of the circuit of the UV lamp 7a, the ion conductor 14, the Microwave generator 7b and / or the spark discharge path 7c.
