Definitions

  • the present invention relates to a valve for regulating an exhaust gas flow of an internal combustion engine according to the preamble of claim 1 and to a heat exchanger for cooling exhaust gas having at least one valve, and a system having at least one valve and having at least one heat exchanger.
  • cooled exhaust gas recirculation is being used in diesel engines and/or spark ignition engines for passenger cars or for utility vehicles as a means of reducing the nitrogen oxide emissions (NOx).
  • NOx nitrogen oxide emissions
  • Reliability problems of these systems are caused, for example, by failures or faults in a EGR valve which are due to the thermal loading by the hot exhaust gas stream or the formation of deposits from the exhaust gas stream.
  • An EGR valve controls, in particular, the mass flow of recirculated exhaust gas which can flow through a heat exchanger, in particular an exhaust gas heat exchanger.
  • the EGR valve can usually be actuated or activated electrically or pneumatically.
  • the EGR valve can have various open-loop or closed-loop control positions.
  • the EGR valve prevents, for example, exhaust gas from flowing through the exhaust gas heat exchanger.
  • a second position for example the entire mass flow of recirculated exhaust gas flows through the exhaust gas heat exchanger.
  • a mass flow of recirculated gas flows through the exhaust gas heat exchanger, said mass flow being between zero mass flow of recirculated gas and the maximum mass flow of recirculated gas.
  • the EGR valve can be arranged downstream or upstream of the heat exchanger, in particular of the exhaust gas cooler.
  • the EGR valve can be arranged in, or adjacent to, the exhaust gas cooler.
  • the EGR valve can be embodied in one piece with the heat exchanger, in particular the exhaust gas cooler.
  • the EGR valve and the heat exchanger, in particular the exhaust gas cooler can be arranged in a system having at least one internal combustion engine and at least one turbine, with which, in particular, a compressor for supercharging charge air or charge air and exhaust gas can be driven, on the outflow side of the turbine, i.e. on the low pressure side, or on the inflow side of the turbine, i.e. on the high pressure side.
  • the EGR valve When the EGR valve is arranged on the inflow side of the heat exchanger, in particular of the exhaust gas cooler, the EGR valve is subjected to high temperature requirements owing to the hot exhaust gas. It is known in this context that the temperature requirement of the EGR valve can be reduced if the exhaust gas is not fed directly to the EGR valve from the exhaust section but instead the recirculated exhaust gas is not fed to the EGR valve and/or the exhaust gas heat exchanger until it has passed through the cylinder head of the engine. As a result of this routing of exhaust gas, heat is already extracted from the hot exhaust gas by the engine coolant before said hot exhaust gas is in contact with the EGR valve. Nevertheless, the EGR valve still experiences very high temperature loading.
  • the arrangement of the EGR valve downstream of the exhaust gas cooler is usually selected in order to reduce the temperature loading of the EGR valve and of the corresponding actuator, in particular of the electrical or pneumatic actuator.
  • the unburnt hydrocarbons (HC) which are contained in the exhaust gas form deposits on the EGR valve in conjunction with soot particles.
  • the deposits which are formed in the EGR valve can be removed again only with difficulty since, for example, the deposits can only be burnt off with difficulty. The deposits cause the valve to become blocked due to sooting up or carbonizing and is therefore no longer functionally capable.
  • the EGR valve on the inflow side of the exhaust gas cooler makes it possible, owing to the high exhaust gas temperatures upstream of the exhaust gas heat exchanger, to burn off the deposits which are formed, for example in relatively high-load operating states of the internal combustion engine.
  • the high temperature loading of the EGR valve also leads to heavy loading of the actuator. Even after the recirculated exhaust gas cools in the cylinder head, the actuator and EGR valve are still heavily loaded by the engine coolant.
  • the applicant's unpublished document DE 102 005 029 322.0 discloses an EGR valve and an arrangement for recirculating and cooling exhaust gas of an internal combustion engine with an EGR valve.
  • the valve device is arranged here on the inflow side of a high temperature cooler, or in another exemplary embodiment the exhaust gas cooler is arranged on the outflow side.
  • an arrangement for recirculating and cooling exhaust gas of an internal combustion engine in which an EGR valve is arranged on the outflow side of an exhaust gas cooler.
  • an EGR valve is disclosed, which has, in particular, an oxidation catalytic converter on the inflow side of an exhaust gas cooler.
  • the object of the present invention is to improve a valve of the type mentioned at the beginning.
  • a valve for regulating an exhaust gas flow of an internal combustion engine which has at least one closure element and at least one actuator for activating the closure element, wherein the valve has at least one heat transfer duct for cooling the valve, through which heat transfer duct at least one first medium can flow.
  • the at last one closure element can perform open-loop or closed-loop control on, in particular, a mass flow of a second medium such as, for example, exhaust gas.
  • the closure element can be actuated by means of an actuator.
  • the valve has at least one heat transfer duct for cooling the valve, through which heat transfer duct at least one medium, in particular coolant such as cooling fluid or air can flow or does flow.
  • the heat transfer duct is embodied as an annular duct.
  • the first medium in particular cooling fluid or air, can particularly advantageously flow from an inlet opening to an outlet opening here.
  • the heat transfer duct has at least one wall pairing whose walls are embodied concentrically with respect to one another.

  • the valve has at least a first opening for the inflow of the first medium and/or at least a second opening for the outflow of the first medium.
  • the first medium can particularly advantageously flow through the heat transfer duct via the first opening, and the first medium can particularly advantageously flow out again from the second opening after it has flowed through the heat transfer duct.
  • the first medium is coolant, in particular a cooling fluid or air.
  • the valve can be cooled particularly advantageously.
  • the valve has at least one plate in which the heat transfer duct is arranged.
  • the heat transfer duct can particularly advantageously be provided in the plate, for example by means of a primary shaping fabrication method such as injection molding, or by means of a material-removing fabrication method such as milling or drilling, and can particularly advantageously be connected to the valve.
  • the plate has reinforcing devices and/or cavities in order to save weight. In this way, the plate can be made particularly lightweight.
  • the plate is connected to a valve housing in a materially joined and/or positively locking fashion.
  • the plate can particularly advantageously be connected to the valve housing, for example by soldering, welding, bonding etc. and/or particularly advantageously connected in a positively locking fashion.
  • the plate is embodied in one piece with the valve housing. In this way, it is possible, in particularly advantageous way, to make savings in terms of assembly processes.
  • the plate has at least a first flange face for fastening purposes. It is particularly advantageously possible to fasten other components, for example an inlet diffuser and so on, to this flange face.
  • a further advantageous refinement is characterized in that at least one aperture for preventing a flow around the heat transfer duct is arranged in the heat transfer duct.
  • This can particularly advantageously prevent first medium, such as for example coolant or air, from flowing from the first opening, in particular the inlet opening, directly to the second opening, in particular to the outlet opening, and in the process not flowing through the heat transfer duct, as a result of which the valve element would not be correspondingly cooled.
  • the valve has at least one sealing element, in particular a flat seal. This can particularly advantageously prevent media, such as for example the first medium, from escaping from the valve and/or other media entering the valve.
  • a heat exchanger for cooling exhaust gas having at least one valve as claimed in one of claims 1 to 12 is also proposed.
  • the heat exchanger has a first flow duct through which the first medium and/or a second medium can flow.
  • the first medium which has in particular previously flowed through the valve, can particularly advantageously be made to flow through the heat exchanger, and/or a second medium can particularly advantageously be made to flow through the heat exchanger.
  • the heat exchanger has a second flow duct through which a third medium can flow.
  • the third medium such as for example exhaust gas
  • the heat exchanger can particularly advantageously be made to flow through the heat exchanger, in particular, the exhaust gas heat exchanger.
  • the second medium is a cooling fluid or air and/or the third medium is exhaust gas.
  • the third medium in particular exhaust gas, can be particularly advantageously cooled by the second medium, in particular the cooling fluid or the air.
  • the heat exchanger has an inlet diffuser for the third medium.
  • the third medium can in particular advantageously be made to flow through the heat exchanger via the inlet diffuser.
  • the inlet diffuser has a second flange face which can be connected to the first flange face of the valve.
  • the valve can particularly advantageously be connected to the heat exchanger.

  • the heat exchanger has at least one bypass valve to permit the third medium to bypass the heat exchanger.
  • a third medium such as, for example, exhaust gas
  • a third medium can particularly advantageously not be directed through the heat exchanger, in particular the exhaust gas heat exchanger, but rather can be directed around it with the result that, particularly advantageously, it is possible to avoid cooling the exhaust gas.
  • a further advantageous embodiment is characterized in that the at least one bypass valve can be activated by means of a second actuator.
  • the bypass valve can particularly advantageously be activated by an electrical or pneumatic or hydraulic actuator.
