Abstract
Mejoras en o relacionadas con un pistón para un motor de combustión interna, teniendo dicho pistón una cámara de combustión formada en su cabeza, teniendo la cámara de combustión un orificio de admisión en la superficie superior de la cabeza, una pared plana de fondo, y una pared lateral que comprende una pluralidad de depresiones cóncavas que se cruzan para definir cúspides dirigidas hacia una región central de la cámara de combustión, comprendiendo dichas cúspides partes curvadas cóncavamente, que se extienden hacia arriba, desde la pared plana del fondo y partes inclinadas que se extienden entre las partes curvadas y la superficie superior de la cabeza a lo largo de la superficie de un cono imaginario que tiene su vértice por encima de dicha superficie superior.
