Definitions

  • the invention relates to an internal combustion engine in modular design.
  • Such an internal combustion engine in modular design can be arranged stationary as well as installed in vehicles, especially in ships.
  • a three-point cam replaces the crankshaft of an internal combustion engine with V-shaped cylinders.
  • the pistons are each connected to a roller via rods, which rolls on the profile of the cam.
  • Each roller is pressed against the cam using a special mechanism.
  • a disadvantage of this known internal combustion engine are the large external dimensions and the complicated structure. Due to the distribution of forces, there is high wear. In continuous operation, the operating conditions also change when the roller is pressed against the cam profile.
  • the object on which the invention is based is to create an internal combustion engine in a modular design which, with a simple construction, low weight and small dimensions, enables a reduction in the wear between the piston and the cylinder and an increase in the efficiency.
  • an internal combustion engine in modular construction which has a cross-shaped cylinder block, which consists of an upper cover with a viewing opening (porthole) and a lower cover, in which two mutually perpendicular cylindrical longitudinal openings and transverse openings are formed.
  • An upper and a lower shell are respectively fastened in the cylindrical longitudinal opening to the upper and lower cover.
  • the cylinders are attached, each of which has a water bushing and a cylinder head.
  • a composite piston is disposed in the elongated cylindrical cavity formed by the upper and lower shells and the cylinders.
  • a combustion chamber is formed between the two faces of the assembled piston and the associated cylinder with cylinder head.
  • a spherical joint with a self-tensioning roller is also attached in each of the two ends of the assembled piston.
  • the three-point cam is arranged, the shaft of which is mounted in the cylindrical transverse opening.
  • the internal combustion engine according to the invention in modular construction has the advantage that it is simple in construction, has small dimensions and is light in weight.
  • the internal combustion engine works with high efficiency, is reliable and easy to repair and allows the connection of a large number of modules, which can be easily replaced.
  • the internal combustion engine shown in Figures 1 and 3 in modular design has a cruciform cylinder block 1 with an upper cover 2, which has a viewing opening 3, and with a lower cover 4, whereby a cylindrical longitudinal opening 5 and a cylindrical transverse opening 6 are formed, which are mutually are vertical and their axes lie in one plane.
  • cylinders 7 with water bushings 8 and cylinder heads 9 are attached along the cylindrical longitudinal opening 5.
  • An upper shell 10 and a lower shell 11 are correspondingly attached to the upper cover 2 and the lower cover 4.
  • the upper shell 10 and the lower shell 11 have a step 12 at one end in order to avoid coaxial displacement.
  • a composite piston 14 is arranged, which consists of an upper body 15 and a lower body 16 and end faces 17, with channels for on both sides Sealing segments 18 are provided. Combustion chambers 19 are located between the end faces 17, the cylinders 7 and the cylinder heads 9. Vertical cuts 20 and horizontal cuts 21 are formed on the assembled piston 14. In the upper cover 2 and in the lower cover 4 as well as in the upper shell 10 and in the lower shell 11, external incisions 22 are provided.
  • a spherical joint 23 which has an axis 24 on which a bearing bush 25 sits, on which in turn a bush with a spherical outer surface 26 is arranged.
  • a socket with the spherical outer surface 26 there is a right spherical segment 27 and a left spherical segment 28, on each of which a roller 29 is seated, which is self-adapting.
  • An upper bearing shell 30 and a lower bearing shell 31 are provided in the cylindrical transverse opening 6, in which a shaft 32 for the cams 33 having three tips is mounted.
  • the three point cam 33 also projects into the vertical notch 20, the horizontal notch 21 and the outer notch 22.
  • the cam 33 which has three points, geometrically adjusts the tension with the self-adapting rollers 29.
  • the embodiment of an internal combustion engine is a module unit that has certain performance data. By connecting individual module units, an internal combustion engine drive set on fire of the desired power is obtained.
  • the modular engine works as follows: The work cycle is initiated by ignition of the fuel mixture in cylinder 7. Due to the pressure of the combustion gases on the end face 17, the assembled piston 14 shifts accordingly, being slidably mounted on the upper shell 10 and on the lower shell 11.
  • the self-adapting role 29 presses against the profile of the three-point cam 33 with a force that is directed perpendicular to the supporting surface, whereby a torque is generated on the shaft 32 under load on the upper bearing shell 30 and the lower bearing shell 31.
  • the reaction of the force to the assembled piston 14 is absorbed by the cylinder block 1.
  • the combustion gases expand on one side of the assembled piston 14, the air in the opposite combustion chamber is compressed at the same time, so that the work required for the compression can thus be transmitted without loss.
