Abstract
Una unidad de camara de combustion util en motores a diesel tiene una camara de combustion (14) definida en una corona (12) de un piston (10), el piston tiene un eje central (16, 18, 518, 524), la camara de combustion tiene una parte central que define un poste, la parte central esta definida al menos en parte por una parte de una esfera, la esfera tiene un radio, el origen del radio esta en el eje central del piston (16, 18, 518, 524), y la camara de combustion (14) ademas tiene una pluralidad de superficies curvas con transiciones tangenciales lisas entre las superficies lisas contiguas, las superficies lisas tienen la parte central esferica y al menos una superficie anular, siendo la camara de combustion (14) simetrica con respecto a un eje longitudinal (16, 216, 316, 416) de la camara de combustion. Ademas se incluye un piston (10) que incorpora la camara de combustion (14) antes mencionada y un metodo para fabricar la camara de combustion (14).
