Definitions

  • the present invention relates to an internal combustion engine.
  • the invention relates to engine construction, and more particularly relates to reciprocating internal combustion engines.
  • the prototype of the proposed engine is the piston internal combustion engine, which according to German patent application no. 2618556 of April 28, 1976 , Class F 01 B 3/02 is known.
  • a rotary power device which has a mechanism in which a reciprocating motion of a stator is converted into a rotary motion of a rotor.
  • the disadvantage of this mechanism is that in this case the cylinder block with the individual cylinder-piston mechanisms is mounted on the rotor. Due to the considerable weight of this cylinder block, very large centrifugal forces arise, which can inevitably lead to stress on the damage of the ball-bearing mechanisms of the supporting or supporting shaft and the lateral rotor parts and of the stator. To avoid such damage, the individual components must be made very high quality, which leads to higher costs. Also, it comes during the idling of such a rotor to unnecessarily high fuel consumption, since the massive rotor must be driven.
  • the aim of the invention is to provide a powerful, economical piston engine of simplified construction with high reliability of the reciprocating mechanism.
  • a reliable and effective internal combustion engine is provided. It is particularly advantageous that can be completely dispensed with a rotational movement of the at least one piston rod and the piston-cylinder mechanisms acting on these. All piston-cylinder mechanisms are thus static in terms of a stator an engine block can be arranged. The weight of the rotor can thus be minimized, which leads to a lower load, for example, the bearings used and to a lower fuel consumption, for example, at idle.
  • the rotor is cylindrical and has on its cylinder surface at least a sinusoidal track, which cooperates with at least one formed on the (also cylindrical) inside of the coupling part ball bearing mechanism.
  • a sinusoidal track with a ball bearing mechanism proves to be a very effective way to convert a reciprocating motion into a rotational motion.
  • the internal combustion engine has a cylindrical, composed of two separable parts engine block, which is formed with slots in which arm-like extensions or plunger of the coupling part, which with the respective piston rods are connected, according to the movement of the piston rods are reciprocable.
  • Such an engine block can be mounted and disassembled in a particularly simple manner, for example to wait for the rotor provided in the engine block. It is also particularly advantageous that all piston-cylinder mechanisms can be arranged with the respective piston rods outside of this assemblable engine block, whereby the maintenance is also simplified.
  • two or four piston rods are arranged with corresponding piston-cylinder mechanisms around the outside of the cylindrical motor, in particular at equal angular intervals, for example in 180 ° or 90 ° intervals.
  • the features 1 *, 6 *, 6 * a, 6 * c, 6 * e.2, 6 * g are in common with the features of the prototype, but the features 2 *, 3 *, 4 *, 5 *, 6 * b, 6 * d, 6 * d.1, 6 * e, 6 * e.1, 6 * e.3, 6 * f are new distinguishing features and also essential, as it allows the use of precisely these features, the stated goal to reach.
