Definitions

  • the subject of the present invention is an exhaust system for internal combustion engines with heat exchanger and exhaust gas treatment unit in an exhaust gas recirculation line.
  • Exhaust systems of internal combustion engines are often formed with heat exchangers, which are used in particular for a return of the exhaust gas in the air inlet region of the internal combustion engine for cooling the exhaust gas.
  • Contamination of the heat exchanger by pollutants present in the exhaust gas reduces its efficiency, so that when the heat exchanger is designed, it basically has to be over-dimensioned in order to ensure over a longer period of time that the heat exchanger has at least the desired performance.
  • an exhaust gas treatment system with an exhaust gas recirculation line in which a heat exchanger is provided. in the Inlet portion of the heat exchanger, an oxidation catalyst is provided. This is provided as a layer on the walls of the exhaust gas recirculation line. So can according to the US 2003/0213230 A1 a reduction of the unbranched carbons can be achieved.
  • the JP 2000146465 also describes an exhaust gas recirculation system, wherein in the exhaust gas recirculation line, a heat exchanger is provided, on whose walls an oxidation catalyst can be provided so that the clogging of the channels can be avoided by particles. Furthermore, it is also proposed to carry out the walls of the exhaust gas recirculation line with a catalyst, wherein its placement and configuration, taking into account Adhesion or accumulation of particles (PM and SOF) takes place.
  • PM and SOF Adhesion or accumulation of particles
  • the object of the invention is to propose a system to be used in the exhaust gas recirculation line comprising a heat exchanger and a catalyst, in which an effective reduction of the contamination of the heat exchanger and at the same time the smallest possible construction volume of the heat exchanger and the catalyst is achieved.
  • the exhaust system according to the invention of an internal combustion engine comprising an intake system and an exhaust outlet, wherein exhaust outlet and intake are connected via an exhaust gas recirculation line, in which an exhaust treatment unit and a heat exchanger are formed, wherein the heat exchanger has a first back pressure and the exhaust treatment unit has a second back pressure, the smaller
  • the first back pressure is characterized by the fact that the exhaust gas treatment unit at such a first distance in the flow direction is formed before the heat exchanger, that during operation of a entering into the exhaust gas treatment unit gas flow is made uniform. This means, in particular, that the back pressure in the flow direction before the exhaust gas treatment unit is influenced by the first dynamic pressure of the heat exchanger.
  • the exhaust treatment unit further comprises a polling body.
  • a honeycomb body an exhaust gas treatment unit can be created, whose properties such as surface, back pressure, etc. can be very accurately einizesteht.
  • metallic or ceramic honeycomb bodies are suitable as honeycomb bodies.
  • honeycomb bodies can be used here in an advantageous manner, as described for example in the DE 197 55 703 A1 , of the WO 90/13736 A1 and the WO 99/11911 A1 are described. With respect to the attachment of the honeycomb body, these applications are fully incorporated by reference.
  • the first distance is selected so that the Cumulate the effect of the first dynamic pressure and the second dynamic pressure.
  • the first distance between the exhaust gas treatment unit and the heat exchanger is less than 15 mm, preferably less than 10 mm, particularly preferably less than 5 mm.
  • Cumulating means here in particular that the dynamic pressure applied in front of the Abaas treatment unit is greater than that second dynamic pressure, the exhaust treatment unit as such would have.
  • the dynamic pressure in front of a component in a flow causes a kind of pressure pad, which leads to a change of Flow leads.
  • the present invention causes instead of two areas with a pressure pad iewe before the heat exchanger and the Abgasbehandiungshim forms only a pressure pad before the exhaust treatment unit.
  • the cumulation of the dynamic pressures advantageously leads to the exhaust gas, before it flows into the exhaust gas treatment unit, having to overcome a back pressure which is greater than the second back pressure of the exhaust gas treatment unit.
  • the dynamic pressure is even significantly greater than the second dynamic pressure.
  • the enlargement of the back pressure causes a homogenization of the flow of the exhaust gas treatment unit and thus the gas flow through the exhaust gas treatment unit and heat exchanger.
  • a heat exchanger is to be understood here in particular also an exhaust gas cooler, with which the recirculated exhaust gas is cooled.
  • the internal combustion engine is in particular a diesel engine, for example a diesel engine of a motor vehicle (eg a passenger car, a truck, a motor-driven two-wheeled vehicle, boat or aircraft) or a stationary-use diesel engine.
  • a homogenization is in particular also understood as a broadening of the probability distribution of the applied velocities.
  • a heat exchanger which has a plurality of tubes through which the exhaust gas flows. These tubes are preferably flowed around by a coolant which flows through the housing of the heat exchanger and which is taken from a not shown cooling circuit of the internal combustion engine.
  • honeycomb bodies for example ceramic or metallic honeycomb bodies, or else wire knit bodies, bodies made of metal foam or the like are suitable as exhaust gas treatment units.
  • Metallic honeycomb bodies may in particular be constructed from at least one at least partially structured metallic layer and optionally at least one substantially smooth layer, which are wound or stacked together and twisted. The each other twisted or wound layers form permeable cavities which are bounded by the layers.
  • the layers are in particular made of a high temperature corrosion resistant material, such as Al or Cr steel.
  • the layers may be interconnected, in particular cohesively, such as by a Hochtemperaturlöt compiler.
  • Both the essentially smooth layers and the at least partially structured layers can have microstructures, guide surfaces, perforations and / or perforations, at least in some areas, which serve for even better mixing of the gas flow.
  • the equalization of the gas flow before entering the exhaust gas treatment unit is advantageously carried out in that the exhaust gas treatment unit is formed relatively close to the heat exchanger. This leads to an equalization of the gas flow already in the exhaust gas treatment unit, so that here the conversion rate is improved because the cross section of the exhaust gas treatment unit is more uniformly exposed to exhaust gas.
  • the volume of the exhaust gas treatment unit can be reduced compared to a conventional structure at the same rate of conversion of pollutants in the exhaust gas. Due to the significantly more efficient conversion rate of the pollutants also reduces the pollution of the heat exchanger, so that it can be smaller in size compared to conventional heat exchangers.

  • the catalytically active coating comprises, for example, a ceramic washcoat which contains materials which catalyze the desired reactions, ie in particular reduce the reaction temperature of these reactions to such an extent that they run to a considerable extent at the temperatures in the exhaust gas recirculation line.
  • Suitable catalysts are in particular noble metals such as platinum, rhodium or the like.
  • the oxidation catalyst coating catalyzes in particular the oxidation of hydrocarbons, since they are responsible for fouling the heat exchanger.
  • the hydrocarbons form a sticky substance that condenses on the cold areas of the heat exchanger and that may further cause soot particles contained in the exhaust gas to adhere to the walls of the heat exchanger.
  • the exhaust gas treatment unit is in particular designed so that the longest possible residence time and the largest possible surface available for the reaction is given.
  • the ratio of the first dynamic pressure to the second dynamic pressure is greater than 2, preferably greater than 10.

As explained above, this leads to an equalization of the gas flow 14, which flows into the exhaust-gas treatment unit 6.
