Definitions

  • the invention relates to an air intake duct system for an internal combustion engine, with a integrated exhaust gas recirculation channel according to the preamble of patent claim 1 or Second
  • this exhaust gas recirculation control has the disadvantage that it is closed when Exhaust gas recirculation valve, in full-load operation of the internal combustion engine, in which no exhaust gas is recirculated via the then connected individual exhaust gas recirculation channels a pressure balance between the individual cylinders of the internal combustion engine leading air intake ducts, whereby the vibration behavior of the sucked air disturbed and the filling of the cylinder is reduced.
  • JP 06081720A an air intake duct system is described in which the disturbance of the Vibration behavior of the air is reduced by that each air intake duct Valve section is associated with the exhaust gas recirculation passage from the respective air intake duct can separate.
  • the control of these valve sections takes place via a central Control valve, with all valve sections when closing the control valve also be closed (Fig.4).
  • Fig. 1 shows a schematic 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, whose Exhaust gas flow, here by an exhaust gas recirculation valve 4, is controllable.
  • the exhaust gas recirculation channel 3 opens via individual channels 5 in each of the individual air intake ducts 2 a.
  • this Air intake duct system 1 is the mentioned disadvantage.
  • valve sections 6 by a common Valve actuator 13 are controlled, which responds to control signals.
  • each individual channel 5 with respect to the air intake duct 2, in which it opens, be closed by a valve section 6 in operating phases without exhaust gas recirculation is.
  • individual channels 7, which in air intake ducts 8 with lead to the same vibration behavior, compared to individual channels 9, in the air intake ducts 10 with another identical oscillatory behavior, in operating phases without Exhaust gas recirculation are separated by a valve section 11.
  • valve sections 6 by a respective separate valve actuator 12th 2 (Fig. 2) responsive to control signals, the valve sections 6 open simultaneously while being adjusted to the desired exhaust gas flow rate.
  • valve sections 11 in the embodiment according to the invention consist of a double seat valve 15, which is a connection between the exhaust gas recirculation channel 3 and two intermediate channels 16, 17 controls, wherein the intermediate channels 16, 17 are each connected to the individual channels 7, 9, in the air intake ducts 9, 10 open with the same vibration behavior.
  • the invention improves over the prior art, lower Pollutant exhaust composition achieved, the proportion of recirculated Exhaust gas to the combustion air can thus be increased to border areas, as the Safety distance to the cylinders with the highest or lowest exhaust gas supply can be reduced.
  • the valve sections 6 can be equipped with plate, slide or roller valves be equipped as valve actuators are electrical or pneumatic question.
