Abstract:
Assembly (10, 101) comprising a precombustion chamber (1) and electrode (2, 22) for producing the ignition and combustion of a fuel (5) while maintaining the flame temperature below a predetermined value, and keeping the flame front (F) in the proximity of an aperture (1p) of the precombustion chamber (1) which opens into one or more cylinders (3i), this fuel (5) being injected towards said aperture (1p) of the precombustion chamber (1) by an injector (4) having its injection nozzle (4n) located within the closed rear end (1c) of the precombustion chamber (1) opposite the aforesaid aperture (1p), the said electrode (2, 22) having the shape of a solid of revolution and being positioned coaxially with respect to said aperture (1p) within the part of the precombustion chamber (1) which terminates at the aperture (1p), and having an axial length (L) such that, at any instant, the aforesaid flame front (F) generated by the combustion is always in contact with the electrode (2, 22), characterized in that a plurality of ignition points (E), or a plurality of sets of these, face said electrode (2) at a plurality of positions located at different distances from the ends of the passage (6).
