Definitions

  • the invention relates to an air intake duct system for an internal combustion engine, with a integrated exhaust gas recirculation duct according to the preamble of claim 1 or 2nd
  • this exhaust gas recirculation control has the disadvantage that it is closed Exhaust gas recirculation valve, in full load operation of the internal combustion engine, in which no exhaust gas is returned via the individual exhaust gas recirculation channels which are then connected to one another a pressure equalization between the individual cylinders of the internal combustion engine leading air intake ducts, which causes the vibration behavior of the intake air disturbed and the filling of the cylinders is reduced.
  • FIG. 1 shows a basic diagram of an air intake duct system 1 for an internal combustion engine according to the prior art, with individual to each cylinder of an internal combustion engine leading air intake ducts 2 and with an integrated exhaust gas recirculation duct 3, the Exhaust gas throughput, here from an exhaust gas recirculation valve 4, can be controlled.
  • the exhaust gas recirculation duct 3 opens into each of the individual air intake ducts 2 via individual ducts 5 on.
  • this air intake duct system 1 there is the disadvantage mentioned.
  • each individual duct 5 with respect to the air intake duct 2, into which it opens, in operating phases without exhaust gas recirculation can be closed by a valve section 6 is, or in an embodiment according to FIG. 3, that individual channels 7, which in air intake channels 8 open with the same vibration behavior compared to individual channels 9, which open into air intake ducts 10 with another same vibration behavior, in Operating phases without exhaust gas recirculation are separated by a valve section 11.
  • valve sections 6 each have a separate valve actuator 12 are controlled (Fig.), which responds to control signals, the valve sections 6 opened simultaneously and adjusted to the desired exhaust gas flow.
  • valve sections 6 pass through a common valve actuator 13 can be controlled, which responds to control signals.
  • valve sections 6 can be equipped with the simplest on-off valves.
  • valve sections 11 consist of a double seat valve 15, which is a connection controls between the exhaust gas recirculation channel 3 and two intermediate channels 16, 17, wherein the intermediate channels 16, 17 are each connected to the individual channels 7, 9, which in the Air intake ducts 9, 10 open with the same vibration behavior. This reduces the effort required for valve actuators.
  • the invention improves, less than the prior art Exhaust gas composition containing pollutants reached, the proportion of the recycled Exhaust gas in the combustion air can thus be increased to the limit because the Safety distance to the cylinders with the highest or lowest exhaust gas supply can be reduced.
  • the valve sections 6 can be any with plate, slide or Roller valves can be equipped, as valve actuators come electrical or pneumatic question.
