A description is given of an assembly (10) consisting of a precombustion chamber (1) and electrode (2), 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 the 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), in which the said electrode (2) has the shape of a solid of revolution and is positioned coaxially with respect to the said aperture (1p) within the part of the precombustion chamber (1) which terminates at the aperture (1p), and has 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). |
