Abstract

A self-igniting internal combustion engine piston comprises a dynamically balanced piston cavity 3 which has a conical side wall 4 in which the inlet opening 5 is smaller than the maximum diameter of the piston cavity 3. The neck 5 of the inlet opening is provided with an encircling collar 6 which projects radially inwards, the area leading from the side wall on to the inner side of the collar being formed by a transitional radius 8. A multijet injection nozzle 17 having four jets injects fuel into the piston cavity by spraying it on to the side wall 4. Specific dimensions are disclosed which retain in the piston cavity 3 as much as possible of the injected fuel. <IMAGE>
