Definitions

  • the invention relates to a suction line part of the type specified in the preamble of the first claim and is based on the generic DE-OS 1576355.
  • a device for venting the housing of injection internal combustion engines in which a ventilation line connected to the machine housing is connected to the line system for the intake air at a point upstream of the throttle valve.
  • the flap connection for the throttle valve or an adjacent line part has a heat exchanger for a heating medium.
  • ice formation in the throttle valve area can still be determined in some cases. Those ice formations are caused by condensate accumulating after the internal combustion engine has been switched off, which finally freezes - since there is no heating effect when the internal combustion engine is at a standstill.
  • the object of the invention is therefore to develop such a suction line part in such a way that the risk of icing of the throttle valve caused by the latter effect is also prevented.
  • crankcase ventilation line By opening the crankcase ventilation line into a geodetically underlying trough-shaped recess of the intake line part, it is ensured that the condensate that accumulates in the mouth region after the internal combustion engine has been switched off collects in that trough-shaped recess and possibly causes ice formation there. This reliably prevents the throttle valve from icing up.
  • heating is carried out according to claim 2 by means of a heated fluid (for example the coolant of the internal combustion engine), it is particularly advantageous to provide the trough-shaped depression in an attachment element, the wall of which is flowed through by this fluid and which is detachably connected to the intake line part, since this when disassembling the intake line part, the fluid circuit does not have to be opened, but that attachment element can simply be separated from the intake line part.
  • a heated fluid for example the coolant of the internal combustion engine
  • a throttle body is shown as an intake line part with a flange-mounted attachment element in section.
  • a schematically illustrated throttle valve connector (intake duct part 1) is arranged in the intake tract of an internal combustion engine (not shown) and is provided with a throttle valve 3 which can be pivoted about the shaft 2. Upstream of that throttle valve 3 opens into a breakthrough 4 of the intake line part 1, a crankcase ventilation line 5, which branches off from a suitable location of the crankcase, not shown, of the internal combustion engine.
  • the crankcase ventilation line 5 is plugged onto a connecting piece 6 of an attachment element 7, which has a trough-shaped recess 8 and is flanged to the intake line part 1 by means of two screw connections 9a, 9b.
  • an annular channel 10 is provided, which is connected to the coolant circuit of the internal combustion engine via an inlet connection 11 and an outlet connection 12.
  • Condensate which forms in the area of the opening 4 when the fresh air guided through the intake line part 1 meets the blow-by gases guided through the crankcase ventilation line 5, partially collects in the trough-shaped depression 8.
  • the add-on element 7 is heated, icing up of this condensate is reliably ruled out.
  • condensate residues can freeze inside the trough-shaped depression 8, but do not have a disruptive effect. Without that trough-shaped depression 8, however, condensate residues would accumulate in the gap area 13 between the throttle valve 3 and the inner wall of the intake line part 1. Icing at this point would impede the freedom of movement or mobility of the throttle valve 3.
  • the trough-shaped depression 8 lying below is provided on the intake line part 1 in the mouth area of the ventilation line 5, that is to say in the area of the opening 4.
