Abstract

Un pistón de motor diesel y un método para hacer el pistón. El método involucra el fundir el pistón con geometrías complejas incluyendo características de corte bajo. El fundido usa un molde desechable agregado que puede ser removido de la parte como fraguada. En una forma, la geometría compleja incluye un recipiente de combustión de corte bajo formado en el domo de pistón, mientras que en otra este puede incluir un conducto de enfriamiento interno. Los conductos internos y el recipiente de corte bajo pueden ser producidos usando el molde desechable agregado.
