Improvements in the combustión engines for operation with heavy fuels whose improvements consist essentially in practicing in the head or bottom of the piston an axial cavity of appropriate shape with its considerably larger upper opening that constitutes the combustión chamber in whose wall and between the edge and the upper segment that could be double located very close to it, several radial holes are practiced through which it reverts to the interior of the chamber the fuel condensed in the wall of the cylinder which pushed upwards by said upper segment penetrates through said holes contact with the hot surface of the chamber is vaporized and said cylinder possibly having a recess peripherally surrounding the upper edge thereof in which the entrained fuel is deposited for its passage to the chamber.
