An assembly includes a precombustion chamber and electrode, for producing the ignition and combustion of a fuel while maintaining the flame temperature below a predetermined value, and keeping the flame front (F) in the proximity of an aperture of the precombustion chamber which opens into one or more cylinders. The fuel is injected towards the aperture of the precombustion chamber by an injector having its injection nozzle located within the closed rear end of the precombustion chamber opposite the aperture. The electrode has the shape of a solid of revolution and is positioned coaxially with respect to the aperture within the part of the precombustion chamber which terminates at the aperture, 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.
