Definitions

  • the invention relates to an internal combustion engine with at least three cylinders having the features of the preamble of patent claim 1.
  • an internal combustion engine with at least two cylinders is known.
  • the internal combustion engine has an inlet and an outlet side for the charge exchange, as well as a web region between the cylinders.
  • the cylinder head and / or the crankcase of the internal combustion engine have on the inlet side a first and on the outlet side a second coolant channel oriented substantially parallel to a longitudinal axis of the internal combustion engine.
  • the proposed internal combustion engine is characterized in that the first coolant channel in the web region is conductively guided by at least one bore to the second coolant channel coolant.
  • Object of the present invention is to show a measure, such as an internal combustion engine with at least three cylinders in the direction of its longitudinal axis uniformly, d. H. can be cooled with a low temperature difference from land area to land area.
  • Fig. 2 shows a horizontal section through the internal combustion engine 1 with the schematically drawn, inventive coolant circuit.
  • the coolant flows from the coolant inlet channel 11 into the first coolant channel 7 and from there mainly across the cylinder head 3 and through the web bores 9, 9 '.
  • the coolant is in this case conveyed into the second coolant channel 8 and from there further in the direction of the coolant pump, not shown.
  • the rest of the coolant circuit is not considered here.
