Definitions

  • the invention relates to a four-cylinder internal combustion engine according to the preamble of the claim.
  • a four-cylinder internal combustion engine of this type is described in AU-B-36 879 (AU-B-53 40 84).
  • the four working cylinders are arranged such that their axes are arranged in a plane perpendicular to the output axis.
  • the translational movement of the working pistons and the piston rods rigidly connected to them into a rotational movement of the drive takes place by means of a cam drive transmission device.
  • the cam drive comprises a link moved by the pairs of working cylinders, in which an eccentric part of the output is arranged and driven by it.
  • each piston requires its own crank pin within the crankshaft, so that a large overall length for the crankshaft very quickly results with the resulting difficulties in its storage.
  • the manufacture of such cranked crankshafts is expensive.
  • the overall length of the entire engine is also large.
  • the rectilinear movement of the two piston rods enables an effective sealing of the cylinder space from the crankcase by means of partition walls which are only penetrated by the piston rods, the bearings of which can be sealed relatively easily.
  • partitions also result in a rigid construction for the motor housing, and the dynamic forces occurring on the crank loop drive can occur in the motor housing. can be easily recorded.
  • the overall frictional forces are reduced in that the crank loop frame itself does not need to be stored. All of these measures shorten the overall motor length.
  • the effective sealing of the interior of the crank loop drive from the cylinder chambers with their chemically aggressive climate increases the service life of the internal combustion engine.
  • the object of the invention is to achieve further conceptual improvements by means of a new design of the boxer engine type mentioned, in particular to create a four-cylinder internal combustion engine using the boxer principle, the working pistons of which, coupled via rigid piston rods, can act as possible on a crank pin.
  • the invention thus achieves an astonishingly simple manner in a compact engine design and a large number of bearing points are saved, as a result of which the power-to-weight ratio is improved and the construction volume is reduced, and in particular the construction length is shortened.
  • constructive simplifications are achieved with regard to the crank output, which also makes engine production cheaper, since only crank shaft cranking with a crank pin is required for a four-cylinder engine.
  • the balancing masses can be reduced and the smooth running of the internal combustion engine improves. This also increases the lifespan.
  • the so-called modular principle can be carried out in a simple manner, so that motors of different power ranges can be realized with the same structural units.
  • Figure 1 is a four-cylinder internal combustion engine according to the invention in a sectional plane through a pair of axially opposite working cylinders;
  • FIG. 2 shows the internal combustion engine according to FIG. 1 in a sectional plane parallel to the first sectional plane through a second pair of axially opposite working cylinders and
  • FIG. 3 shows an enlarged longitudinal section through the crankshaft region of the internal combustion engine according to FIG. 1.
  • a first pair of working cylinders has two working cylinders 1 and 2, which are arranged opposite one another with the same axis. They are provided with working pistons 3 and 4, on which piston rods 5 and 6 are rigidly attached. On the other hand, these are firmly connected to a frame part 7, which includes a straight-line backdrop 8.
  • the longitudinal axis L8 of the link 8 extends at an angle of 90 ° transversely to the longitudinal axis L1, L2 of the two working cylinders 1 and 2.
  • a sliding block 9 moves on a crank pin 10 (with the longitudinal axis 24) of a crank drive 20 an output shaft 21 (with longitudinal axis 23) is rotatably mounted (see FIG. 3).
  • a second pair of working cylinders has two working cylinders 11 and 12, which are also located opposite one another with the same axis. They are provided with working pistons 13 and 14, on which piston rods 15 and 16 are rigidly attached. On the other hand, these are firmly connected to a frame part 17, which includes a rectilinear backdrop 18.
  • the longitudinal axis L18 of the link 18 extends at an angle of 90 ° transversely to the longitudinal axis L11, L12 of the two working cylinders 11 and 12.
  • a sliding block 19 moves, which is also rotatably mounted on the crank pin 10 of the crank mechanism 20.
  • the two longitudinal axes L8 and L18 of the two scenes 8 and 18 also intersect perpendicularly.
  • the two frame parts 7 and 17 lie side by side on the crank pin 10 of the crank output 20.
  • the bearing of the output or crankshaft 21 is, since it is not part of the invention, neither described nor shown in detail.
  • the synchronization of all four working pistons achieved by the selected arrangement of two frame parts on a crank pin has the advantage that the balancing mass corresponds to the translationally moving mass of a conventional two-cylinder internal combustion engine .
  • the centrifugal force in each output or crankshaft position is just as large as the resulting mass of two two-cylinder internal combustion engines. All that remains is a residual mass force, resulting from the small distance between the piston rods, which are offset by 90 °, and the masses that move with them in a translatory manner.
