Definitions
- the present invention relates to an internal combustion engine, comprising:
- a cylinder head having a cylinder head, a cylinder wall and a piston movable along a cylinder axis, which has a piston crown, wherein a main combustion chamber is formed between the cylinder head base, cylinder wall and piston crown,
- a prechamber inserted into a bore of the cylinder head and fixed relative to the bore in the circumferential direction of the bore, the axis of the bore being at least substantially parallel to the cylinder axis and wherein a prechamber combustion space is formed in the prechamber,
- the object of the invention is to gozu-form a generic internal combustion engine such that rapid combustion is ensured without burdening the cylinder head bottom or the piston head thermally excessive. This object is achieved by an internal combustion engine with the features of claim 1.
- each transfer opening does not each enclose the same angle with the cylinder axis, it is possible to choose the angle which each transfer opening encloses in each case with the cylinder axis for each transfer opening in such a way that the ignition torches emerging from the transfer openings during operation of the internal combustion engine Cylinder head floor and the piston crown have a maximum distance. On the one hand, this causes the thermal stress on the cylinder head bottom and piston crown to be minimized. On the other hand, such a maximum volume of the main combustion chamber is detected, which ensures rapid combustion.
- the geometry of the transfer openings (eg diameter and shape) can be varied.
- the size and the pulse of the respective Zündfackel can be adapted to local requirements.
- the prechamber is fixed in its circumferential direction in the bore of the cylinder head (that is, has a predetermined angular position), since otherwise it is not possible to match the angle of the transfer openings to the respective geometric condition of the main combustion chamber.
- the internal combustion engine is designed as a stationary gas engine, in particular, which can be coupled to a generator for power generation.
- FIG. 1 Schematically a section of an inventive
- Fig. 2 is a plan view of the cylinder head floor of Fig. 1 shown
- FIG. 3 is a sectional view along the sections A and B of FIG. 2, 4a, 4b a more realistic plan view of a cylinder head floor of an inventive internal combustion engine and a detailed representation thereto and
- a main combustion chamber 4 of an internal combustion engine according to the invention can be seen, which in reality, of course, usually more than one main combustion chamber 4 has.
- the main combustion chamber 4 is formed by the piston head 9 of a piston 8, the cylinder wall 7 and the cylinder head bottom 5 of a cylinder head 6.
- Recognizable is further an antechamber 1, in which a Vorhuntbrennraum 3 is formed, which via a channel 12 with transfer openings 2,2 ' (In Fig. 1, only one transfer opening 2 is shown) is connected to the main combustion chamber 4.
- the distance between the cylinder head bottom 5 and the piston head 9 in the main combustion chamber is not the same everywhere.
- Another reason for a varying distance may be the design of the piston, which may differ from a rotationally symmetric shape (z. B. heart piston and various well piston).
- the transfer openings 2, 2 'do not all enclose the same angle ⁇ with the cylinder axis Z (see FIG. 3).
- the angle a, a 'for each crossing opening 2,2' is selected so that the distance between the operation of the internal combustion engine from the transfer openings 2,2 'exiting Zündfackeln to the cylinder head 5 and the bottom of the piston 9 is maximum. This takes into account that in the embodiment shown, the distance in the region of the valve webs is greatest, since the valve webs are reset and the valves are flush.
- angles 90 ° minus ⁇ and 90 ° minus ⁇ ' are always plotted in the figures, instead of ⁇ and ⁇ ', respectively.
- FIGS. 4 and 5 show a more realistic view of a device according to the invention Embodiment, which can be seen in this embodiment, that a wreath of a total of eight transfer openings 2,2 'is provided, each in the circumferential direction successive-following transfer openings 2,2' have a different angle a, a '.
- a wreath of a total of eight transfer openings 2,2 'is provided, each in the circumferential direction successive-following transfer openings 2,2' have a different angle a, a '.
- Fig. 5a nor the representation of an example of how the prechamber 1 can be fixed in the circumferential direction of the bore 10, namely in this embodiment by positioning pins 11.
- it could also be provided to clamp the antechamber 1 in the bore 10, to weld or otherwise apply a suitable fixing method that allows mounting with a predetermined angular position.
- Fig. 5b shows the projecting into the main combustion chamber part of the prechamber according to the invention, wherein two crossing openings 2, 2 'with different angles ⁇ , ⁇ ' can be seen.
- Fig. 1 an asymmetrical prechamber 1 is shown, while the remaining figures show symmetrical prechambers 1.
- the invention is applicable to both types of prechambers 1.
