Definitions

  • a further acceleration of the rotation takes place in that the ignition jet of the spark plug flows out of an outflow channel and the direction of this channel also takes place in the direction of the rotation, so that the rotation flow is in turn supported thereby.
  • the spark plug 7 is located in the cylinder head 6. According to FIG. 1, this is seated in a prechamber 8 with an adjoining outflow channel 9, the longitudinal axis of the outflow channel 9 pointing in the direction of the rotation 20 of the fuel-air mixture generated in the combustion chamber 15.
  • the left piston 3 has an oblique piston head, which is directed obliquely upward in the form of a straight line 25, the straight line 25 being parallel and at a short distance from the associated straight wall of the cylinder head 6 in the top dead center position, thereby forming a pinch gap 19 .
  • a groove 28 is machined in the piston 2, which forms a piston arch 12, which in turn runs into a straight line 29.
  • the straight line 29 in connection with an assigned upper cylinder head wall forms a second, shorter pinch gap 18.
  • a pinch gap 19 is formed between the top edge of the piston 10 and the cylinder head 6, from which the gas mixture flows out at a very high pressure in the direction 16 and generates a rotational flow in the combustion chamber 15.
  • the rotation is generated by the shape of the cylinder arc 11, the piston arc 12 and of the deflection bend 13. It is also conveyed in the flow by escaping gases from the pinch gap 18. A further conveyance in the flow direction is brought about by the outflowing fuel gas from the spark plug chamber 8 via the outflow channel 9.
  • the mixture When ignited, the mixture burns in the pre-combustion chamber 14 and flows at high pressure and speed in the direction 16 into the main combustion chamber 15a, where a rotation also occurs in this way.
  • This rotation is further extended or supported by the ignition of a second spark plug 31.
  • the ignition of this second spark plug 31 takes place only later in comparison to the ignition of the first spark plug 7, namely only when the mixture ignited by the first spark plug 7 has reached the region approaches the second spark plug 31.
  • an injection nozzle 33 is arranged in the channel of the inlet slot 4 so that it injects fuel into the channel at a certain point in time.
  • the injection time is controlled so that the fuel in the overflowing air quantity only in the second part of the total amount of air is injected.
  • the richer mixture is in the area of the nip 19 or the recess 30. There it is ignited by the spark plug 7 and flows in the directions 16 and 32 into the other fuel-free ones or lean part of the combustion air. In this way, the ignited mixture rotates in directions 16 and 20.
  • the second spark plug 31 can be omitted.
  • pistons 2 and 3 are interchanged with one another, inlet slot 4 and outlet slot 5 according to FIG.
