Definitions

  • the invention relates to an exhaust gas recirculation line for internal combustion engines according to the preamble of claim 1.
  • the invention has for its object to save the additional construction effort and to protect neighboring components from the radiation of heat.
  • FIG. 1 shows a top view of a cylinder head 1 with an exhaust gas recirculation system.
  • the exhaust gas recirculation system essentially consists of an exhaust pipe 2, a Check valve 3, an exhaust gas cooler 4 and a charge air line, not shown here educated.
  • the exhaust gas to be returned passes through coming from the exhaust pipe 2 initially a butterfly valve 5, then flows through the exhaust gas recirculation line 6 and passes through the check valve 3 when pressure peaks occur, and the exhaust gas cooler 4 into the charge air pipe.
  • the exhaust gas from the exhaust pipe 2 to the exhaust gas cooler 4 is now through a Exhaust gas recirculation line 6, which is in one of the end faces of the cylinder head 1 is integrated that it is guided through the cooling water chamber 7.
  • a line is saved, which is on the front of the Cylinder head 1 would take up additional space: The line would be in their Radiate considerable heat to the environment when installing in a vehicle Risk of fire and should be isolated.
  • Another advantage of the invention Arrangement is that by installation in the cooling water chamber 7 a noticeable pre-cooling of the exhaust gas is achieved, so that the actual exhaust gas cooler 4 can be dimensioned smaller.
  • the cooling effect of the exhaust gas recirculation line 6 can be increased further by that it has exhaust-side cooling fins, which the exhaust gas recirculation line 6 in the longitudinal direction pull through and the together with the cylinder head 1 in casting technique can be performed.
  • the check valve 3 is a flap valve formed, which opens when 6 exhaust pressure peaks via the exhaust gas recirculation line meet a tongue 8 in the direction indicated by the arrow.
  • the check valve 3 can advantageously be a structural unit with a seal 10 form which is arranged between the cylinder head 1 (Fig. 1) and the exhaust gas cooler 4 is.
  • the deflection of the tongue 8 can be limited by a stop 9 in turn forms part of the seal 10.
  • the exhaust gas flows after passing the tongue 8 in the exhaust gas cooler 4 and after cooling in the charge air line.
  • FIG. 3 A section III-III through the front end of the cylinder head 1 is shown in FIG. 3.
  • the exhaust gas recirculation line 6 is embodied in two channels here.
  • the two exhaust gas recirculation lines 6a, 6b penetrate the cooling water chamber 7.
  • the exhaust gas is already here pre-cooled. A heat radiation to the environment is completely impossible, isolation is therefore not necessary.
  • a butterfly valve 5 (Fig. 1) is provided, which by the actuator 5a can be actuated.
