Definitions

  • the invention relates to an air-cooled reciprocating internal combustion engine with at least one row of cylinders and juxtaposed, essentially cubic single cylinder heads, with slugs for receiving fastening screws, at least one intake and exhaust valve, the valve stems being aligned essentially parallel to the cylinder axis and by the The plane of the valve stems is rotated at an acute angle to the longitudinal direction of the internal combustion engine, the inlet duct begins on the side against which the cooling air flows, approximately in the middle of the cylinder head, and the outlet duct is oriented essentially perpendicular to the exhaust air side, with a lateral guide plate on the last cylinder heads of each row is provided.
  • a generic air-cooled reciprocating internal combustion engine with corresponding single cylinder heads is known from the engine series 924 to 930 from Tatra-Werke, CSSR, and in the specialist book "Air-cooled vehicle engines by J. Mackerle, Frank'sche publishing house, Stuttgart, 1964" on pages 171 to 173 and 524 to 528 shown and described.
  • the cylinder heads and the cooling fins are designed in such a way that each cylinder head forms a cooling unit and is flowed through in a substantially straight line.
  • One cylinder head like the side baffles, only forms one loading limit for the air flow to the other cylinder head.
  • the head is only for limited services suitable, especially as the area of the outlet channel and the areas located between outlet passage and the cylinder tube can not be sufficiently cooled. This is also because the slugs for the fastening anchors of the cylinder head on the crankcase are guided up to the upper edge of the cylinder head.
  • the object of the present invention is therefore to improve the air-cooled reciprocating internal combustion engine according to the generic term or its cylinder heads and their cooling in such a way that higher outputs can be achieved so that the cylinder head remains strong, good cooling air flow with good cooling of the hot Best places are reached and inexpensive production is possible.
  • the object of the invention is achieved in that adjacent cylinder heads by means of the outer contours of the gas exchange channels in connection with central areas arranged between the valve stems and with cooling fins oriented transversely to the cylinder axis, one or, depending on the size of the cooling fins, a plurality of curved or S-shaped cooling air channels in the cylinder Form cylinder head section and that the cover plate section of the cylinder head facing the cylinder is provided on the circumference essentially on the exhaust air side and on the side opposite the inlet valve stem with cooling fins and has the slugs for the fastening screws.
  • the cylinder head according to the invention is in one piece, but can be in a cylinder head section facing away from the cylinder (fin section) and in the cover plate section (deck section) can be divided.
  • the cover plate section is so thick that sufficient strength is achieved and an overall stable, uniform seal to the cylinder tube is achieved.
  • the slugs for the fastening screws of the cylinder head also end with the cover plate section, so that the cylinder head section above it, which faces away from the cylinder, is determined by the gas exchange channels and cooling fins and a central area.
  • the plane leading through the valve stems is preferably rotated by 30 ° to the longitudinal direction of the internal combustion engine.
  • the locking plates in the area of the cover plate section between two cylinder heads have recesses through which the air flow guided between the cover plate sections can escape.
  • the side baffles also have widenings which correspond to the guidance by a further cylinder head. They are also advantageously integrally connected to the corresponding part of the locking plate.
  • 1 designates a single cylinder head of an air-cooled reciprocating internal combustion engine, which is essentially cube-shaped in its outer shape and has an inlet channel denoted by 2 and an outlet channel denoted by 3, which extend on opposite sides of the cylinder head 1 .
  • the inlet channel 2 and the outlet channel 3 are controlled by inlet valves, not shown, which limit the channels at their end facing the cylinder, not shown.
  • the cylinder heads 1 are also not shown, but in FIGS. 1, 3 and 4, the flow of cooling air flows towards them, which is supplied on the inlet side of the inlet duct and leaves the cylinder heads on the outlet duct side.
  • the plane running through the valve stems of the valves, not shown, is rotated at an angle of 30 ° to the longitudinal direction of the internal combustion engine.
  • the inlet duct 1 begins in the middle of the cylinder head and leads, passing into a swirl duct, to the outside of the cylinder head.
  • the exhaust duct 3 is guided to the outside on the shortest path and therefore opens offset to the center of the cylinder head perpendicular to the exhaust side of the cylinder head 1.
  • a central region 4 is provided, which in the Embodiment of the invention is made solid and in one piece with the cylinder head.
  • This configuration of the cylinder heads creates an arc-shaped or S-shaped cooling air duct 5 in connection with the adjacent cylinder head, in which the cooling air is deflected several times and is therefore optimally utilized.
  • the cylinder head has, as can be seen in particular from FIGS. 1 and 2, a cover plate section 6, which is not a Darge facing the cylinder and is essentially solid with little ribbing, and a cylinder head section 7 facing away from the cylinder.
  • the cylinder head section 7 has cooling fins 8 which are aligned substantially perpendicular to the cylinder axis and from the channels 2 and 3 or the central region 4 to the cube-shaped outer contour of the cylinder heads.
  • the D eckplattenabites 6 has at its corners slug 9 for fixing screws, which are shown in Fig. 5.
  • the cover plate section 6, which can be seen in particular from FIGS. 1 and 4, has oblique ribs 8a on the side shown there, opposite the inlet channel 2, which are oriented at an acute angle to the cylinder axis. Between these inclined ribs 8a and the cylinder (not shown), which can also be seen in FIG. 2, there is a channel 10 in which channel ribs 8b are arranged.
  • the channel 10 is widened in connection with the inclined ribs and the channel ribs, so that the combined partial air flows, as can be seen from FIG. 4, can flow off.
  • the adjacent cylinder head can have an adapted recess on the adjacent side.
  • the cover plate section 6 has on the exhaust side at an acute angle to the cylinder axis and V-shaped under the outlet channel 3 V-ribs 8c, which are followed by parallel ribs 8d aligned parallel to the cylinder axis.
  • the incoming cold air (outlined arrows) is divided into a main air flow, which is the arc-shaped or S-shaped cooling air flows through and into a partial air flow that flows laterally through the cover plate section.
  • the cooling air heats up on the walls of the cylinder head and exits as heated air (arrows drawn in bold).
  • Z wipe two cylinder heads provided on the exhaust side of a barrier sheet designated 11, which, see F ig. 5, has a throughflow distance on the side and to the edge of the cylinder heads facing the cylinders, as a result of which the cooling air quantity is throttled and also flows around the cylinder head completely on the exhaust air side for the purpose of good cooling effect.
  • the locking plate 11 has a recess 13 through which the cooling air flow coming from the lateral ribs of the cover plate section 6 can exit.
  • the locking plate 11 is bent at a right angle in the region of the upper edge of the cylinder heads and follows the upper contour of the cylinder heads (FIG. 4). This will make the bow or S-shaped. Cooling air channel limited upwards and cooling air also led to the cooling fins of the cover plate section 6 on the exhaust side below the outlet channel 3.
  • baffles 14 are provided, which are shaped so that they replace the outer contour of an adjacent cylinder head and each part of the corresponding locking plate, so that the arc-shaped or S-shaped cooling air duct is retained.
  • This configuration of the cylinder heads results in a very good cooling air flow and a very good utilization of the cooling air, so that the central area can be made solid and an injection nozzle of a self-igniting diesel internal combustion engine can be used in a bore 15 in the central area at an optimal combustion point that the injector overheats.
