Definitions

  • the invention relates to an air-cooled multi-cylinder internal combustion engine according to the preamble of claim 1.
  • Such an internal combustion engine is known from DE-AS 1 205 772.
  • the cooling air flowing in transverse to the cylinders flows along the broad side of the transverse ribs and is deflected on the rear cooling air outflow side of the cylinders by columns which are designed to be streamlined.
  • baffles are attached to the pillars, the type of fastening of which is not specified. Such baffles are usually screwed on and cause undesirable noise emissions.
  • the object of the invention is to provide an air guiding device which can be produced and assembled at low cost and does not constitute an additional source of noise.
  • FIGS. 1 and 2 three individually cast cylinders 2, 3, 4 are arranged in a row next to one another in a crankcase 1 of an internal combustion engine and together with the cylinder heads 6 with the crankcase 1 placed on the cylinders 2, 3, 4 by means of expansion screws 5 screwed.
  • the cylinders 2, 3, 4 are provided all around with ribs 7 extending transversely to their longitudinal axis, between which cooling air is blown through.
  • a deflecting part 8 covering all cylinders, which is cast in one piece from light metal and is attached to the crankcase at its three fastening eyes 9 located centrally to the cylinders 2, 3, 4 and screwed to it.
  • the deflection part 8 is double-walled.
  • the fastening eyes 9 are located in the center of the air outlet openings 10, which are arranged in the area of the center planes 2 ', 3', 4 'of the cylinders, run radially to the cylinders and extend over their entire height.
  • the deflecting part In the area between the cylinders 2, 3 and 3, 4, the deflecting part has V-shaped bends 11 pointing towards the cylinders 2, 3, 4, at which the cooling air flowing between the cylinders is deflected by 90 ° and led to the air outlet openings 10 becomes.
  • This deflecting part 12 also serves as a knocking bridge in addition to the air guidance, in that it forwards the noise coming from the cylinders caused by knocking combustion to a knocking sensor 15 which is screwed onto the deflecting part 12 approximately in the middle of its longitudinal extent.
