Definitions

  • the invention relates to a two-cylinder, four-stroke internal combustion engine with an angle den of 0 degrees formed by the cylinders, in which the pistons work on different cranks of a crankshaft, the crankings of which are offset by an angle with respect to one another.
  • this machine is designed as a two-stroke machine with double-acting working cylinders, in which we want to dispense with a flywheel through this cylinder arrangement.
  • the invention is based, to find a crank offset angle for a two-cylinder four-stroke internal combustion engine with an angle formed by the cylinders of 0 degrees so that a perfect balance of the inertia forces of the second order arises.
  • the 1st order mass forces are to be eliminated by known compensatory measures.
  • axes of the first and second cylinders of the internal combustion engine are designated 1 and 2. They are on one level.
  • the pistons 3 and 4 work on connecting rods 5 and 6 on the cranks 7 and 8 of a crankshaft, the
  • cranks of the cranks 7 and 8 is designated ⁇ , it is 270 degrees.
  • the arrow 10 indicates the direction of rotation of the crankshaft.
  • Fig. 2 shows a diagram of the course of the 2nd order mass forces of the first and second cylinders in the respective crank pitches and their mutual cancellation.
