Definitions

  • Multi-cylinder internal combustion engine according to the type of the main claim.
  • Multi-cylinder internal combustion engines of this type are known several times, the primary aim being to improve the efficiency of the engine in that the force transfer to the cranks takes place in the explosion stroke as far as possible and therefore optimally by the angle between the piston axis and the connecting rod being as small as possible, while the suction stroke enables a slower suction of the engine due to the position of the connecting rod relative to the cylinder axis at a large angle, which enables the combustion chamber to be filled cheaply even without charging.
  • this design with two connecting rods per piston or cylinder unit and with two cranks offers a smoother running of the machine, also thanks to the better mass balance of the crankshaft and connecting rod. This improvement in efficiency leads to cheaper fuel consumption and a better torque compared to internal combustion engines with only one piston rod, but at the expense of an additional effort in production, namely the second
  • the fiction, contemporary internal combustion engine with the characterizing features of the main claim has the advantage that the internal combustion engine works almost vibration-free.
  • the combination of two cylinder units, each with Cylinder unit two driven wheels in the transmission of the linear stroke to the rotary movement a particularly favorable torque and extremely favorable fuel consumption can be achieved.
  • the savings in fuel consumption in particular, quickly amortize the additional costs for the second driven wheel and other necessary additional parts in the driven unit.
  • the output unit is equipped with intermeshing gear wheels which are connected to the cranks.
  • gears instead of gears, chain, belt or other drives could of course also be used, although in some configurations certain advantages for the connecting rod pairs with respect to mirror-symmetrical power transmission were lost.
  • the driven wheels have the same diameter and are arranged symmetrically to one another with parallel axes of rotation.
  • the drive wheels mesh directly with each other or each driven wheel engages in two of the other driven wheels.
  • a plurality of such units having a first, second or additional cylinder unit and forming a working plane can be combined in rows to form a series engine, wherein they have a common output shaft.
  • the cylinder units are arranged in a box-like manner with axes parallel to one another. This enables an in-line boxer engine arise with extremely favorable torque and extensive freedom from oscillations or vibrations.
  • the piston is disc-shaped, with a minimum of guide surfaces towards the wall of the engine cylinder. Lateral executives can be minimized because the resulting line of force of the two connecting rods falls into the axis of the piston, eliminating the transverse and tipping forces of the piston. In normal engines there is a not inconsiderable energy-consuming slide pressure.
  • the mass, and thus the thickness of the piston can be determined in the invention by the specifications made for the cooling.
  • the piston can also be made of ceramic or the like. consist.
  • An exemplary embodiment of the invention is greatly simplified as a boxer engine according to the invention and is shown in section in the drawing and is described in more detail below.
  • a boxer engine is shown in longitudinal section with a housing 1 and two mutually facing engine cylinders 2, in each of which a piston 3 operates, and the combustion chambers 4 are closed by cylinder heads 5, in which the engine valves 6 are mounted.
  • two connecting rods 7 are articulated from each piston 3, each of which acts as a crank 8 on the side facing away from the piston 3, so that four crank rods are also present corresponding to the four connecting rods, each with the opposite direction of rotation.
  • These cranks engage gear wheels 9, of which adjacent gear wheels 9 mesh with one another.

Abstract

L'invention concerne un moteur à combustion interne multicylindre comportant un premier ensemble cylindre (11) avec un piston (3) qui agit sur deux bielles (7) agissant elles-mêmes respectivement sur une manivelle (8), ces manivelles étant articulées sur des pignons de sortie (9) synchronisés en rotation l'un avec l'autre. Un deuxième ensemble cylindre (12) de même configuration est associé à ce premier ensemble cylindre (11) sur le côté opposé à la manivelle (8), ce deuxième ensemble comportant également deux manivelles (8) et deux pignons de sortie (9).
