ABSTRACT:
The present invention relates to an internal combustion engine comprising means at cylinder head and piston level for improving combustion while reducing the tendency to knocking and pollution. This engine comprises a double feed system, an intake port for a rich mixture being arranged in a hollow in the cylinder head and comprising a retaining cup at its base, an intake port for a poor mixture and a projecting part at the top of the piston covering the hollow and the retaining cup and defining a precombustion chamber for communicating with a part of the chamber opposite the hollow, via channels made at the base of the projecting part. The invention finds advantageous application in the domain of automobile vehicle construction.
