Definitions

  • the invention relates to a multi-cylinder internal combustion engine, consisting of a single cylinder block with two inclined towards each other Cylinder bores arranged in rows, a common one in Bearing mounted crankshaft, and at least one in one Cylinder head arranged overhead camshaft.
  • the concentration Packing the cylinders in two rows requires a higher energy density, This means that more heat can be removed from a certain block volume.
  • DE 29 22 726 A is a prechamber diesel engine in a narrow V arrangement known, in which the V-angle of the cylinder, probably from the reasons above, is particularly small. This will keep the engine out of the way possible dimension shortened with somewhat larger V-angle. You can see that asymmetrical shape of the piston and the central arrangement of the prechamber for reasons of thermosymmetry. An execution for after Engines working with the direct injection process, especially diesel engines is not due to the given design restrictions think.
  • the aim of the invention is to design a generic engine in such a way that that the disadvantages listed are avoided. It is said to be at least Installation dimensions of the engine are possible, the combustion chambers optimal to design, ensure adequate cooling and the gas flow and fuel supply so that the same in all cylinders Combustion conditions prevail.
  • the goal is set by the combination of the characterizing features of claim 1 achieved.
  • the one-piece Formation of cylinder block and cylinder head has this here Particularly significant advantage that no cylinder head screws are more necessary, thus great freedom of design for the gas exchange channels, the cooling channels and also the gas channels and the injection nozzle or Spark plug prevails.
  • the cooling water jacket can extend far down over the cylinder bottoms. All in all the entire cylinder block can be screwed by eliminating the cylinder head with smaller wall thicknesses and therefore smaller and lighter be built. In extreme cases, it can even be made of light metal his.
  • the bolts are parallel aligned with the axes of the cylinder bores and through the bearing blocks screwed into the cylinder block, the one Bolt assigned to the bearing bracket in opposite directions and in the outside Wall parts of the cylinder block lying in rows of cylinders are screwed in (Claim 2).
  • the inclined bolts require a straight line of force in the cylinder block, the cylinder walls on the outside of the Cylinder block and the bolts are only stressed on the train Cylinder walls on the inside not at all.
  • the Roundness of the cylinders is not affected. So the tapped holes the bolts assigned to a storage chair are also far apart, just be arranged in the outer walls, and yet it is Distance between their points of attack on the camp chair is much smaller, therefore small bending length.
  • the cylinder block is on one with the Bearing chairs attached in one piece crankcase upper part attached (Claim 4). This forms the storage chairs with the crankcase upper part a component that results in a particularly precise bearing of the crankshaft.
  • the cylinder block is placed on this and by means of the bolts between which there are even shorter bolts can. This makes it particularly light, simple and for the automated Installation suitable construction created
  • the injection nozzles inclined in the same direction in both cylinder banks or spark plugs together with the cross current arrangement the gas channels have identical combustion conditions in all Cylinders.
  • the arrangement of the gas channels in the sense of the same geometric For them, constellation, together with the one-piece design, means better cooling and larger cross sections. If it is is a direct injection diesel engine, all injectors inclined towards the inlet side. This allows the injection nozzles in the vicinity the swirl-related constriction of the inlet channel can be arranged where more space and the weakening of the cylinder bottom is the least.
  • the final tract of the longer suction line and the end tract of the shorter suction line (26) are of the same shape. (Claim 6).
  • the one-piece construction given design freedom facilitates the accommodation of the relative large pump nozzle units. By their inclination in the same direction this means a larger number of identical parts for the valve train and the injection of the two cylinder banks.
  • the one shown in Fig. 1 in the usual manner for V-engines cut Engine block 1 is a single casting and consists of a first 1 'and a second 1 "cylinder row with cylinder axes 2 ', 2" and one with it one-piece head part 3. It is therefore a motor in the So-called “monoblock” construction, in the present embodiment around a four or six cylinder engine with an angle of up to 20 ° between the cylinder rows 1 'and 1 ".
  • the engine block 1 consists of cylinder walls 4, each with one Cylinder axis 2 normal cylinder base 5 and the outer contour of the Engine block 1 forming block walls 6. Over the cylinder bottom 5 are Gas routing channels 7, each an intake channel and an exhaust channel, educated. Around these channels 7 and between the cylinder walls 4 and the block walls 6, a cooling water chamber 8 is created, which without Constrictions the gas guide channels 7 and the cylinder walls 4 to far surrounds down.
  • the engine block 1 has one Mating surface 9 to which the base bearings 10 connect. These consist of one bearing bracket 11 and one bearing cover 12.
  • the base bearings, the number and arrangement of which depends on the circumstances are here made in one piece with the crankcase upper part 19.
  • Bearing cover 12 and bearing bracket 11 are on both sides of bolts 13 (13 ', 13 ") penetrates, which is screwed into blind holes 14 in the block walls 6 are.
  • the bolts 13 ', 13 are inclined to one another by the same angle like the cylinder axes 2 ', 2 ". Those of them in the cylinder block 1 initiated tensile force thus acts exactly in the direction of the axially parallel Block walls. Due to the inclined arrangement are in the Blind holes 14 screwed ends of the bolts 13 ', 13 "so far apart from each other that they are screwed into the block walls can. No bending moments are generated.
  • the bearing blocks 11 of the base bearing 10 are in one piece executed with a crankcase upper part 19; in other words: the Engine block is connected to the crankcase upper part by means of bolts 13 ', 13 " 19 connected, which also forms the camp chairs.
  • In the head part 3 are between cooling channels not individually identified Intake port 25 to a cylinder of the first row 1 'and an intake port 26 to a cylinder of the second row 2 ".
  • On the engine block is an intake manifold 27 on one side and a on the other side Exhaust manifold 28 screwed.
  • the inlet channels 25, 26 and the exhaust ports 36, 37 for the cylinders of the two rows are different long. The many other details in this cut are no further described because they are familiar to the engine builder.
  • From Intake manifold 27 (see Fig.1) extend the different lengths Inlet ducts 25, 26, with constrictions 29 towards the end, approximately horizontally up to the cylinder bottoms 5 ', 5 "and form swirl chambers there 34, from which the combustion air through only with its center indicated valves 23 ', 23 "flows into the respective cylinder there is a rectified swirl flow in the cylinders of both cylinder rows generated, indicated by directional arrows 35 ', 35 ".
  • the inlet channel 25 is much longer than the inlet channel 26 to the Inlet manifold facing away from the cylinder bank.
  • the two channels are curved so that they are equidistant open into the intake manifold.
  • Your final tracts are 40.41 geometrically the same, so that for the inflow into the combustion chamber prevailing route the same flow conditions prevail.
  • Outlet channels 36, 37 are also of different lengths and can be straight because they naturally do not need swirl chambers. But you can too be crooked, in any case, by implementing the teaching of Invention be so far apart that they form between their walls 38 cooling water spaces 39, which in the Particularly high thermal load in the vicinity of the outlet ducts Head area reduced.
