Abstract

Bujía de un motor de combustión interna, preferentemente para motores Otto a gas, con una carcasa de la bujía (2) que rodea un cuerpo aislante (1), así como un electrodo central (3) y al menos un electrodo de masa (4) alojado en un portaelectrodos de masa (6), estando la superficie de encendido (12) del electrodo central (3) y la superficie de encendido (26) del electrodo de masa (4) rodeadas por una pared (8) que forma una cámara (5) abierta o cerrada por el lado de la cámara de combustión, llevando el portaelectrodos de masa (6) al menos un electrodo de masa (4) digitiforme que se extiende al interior de la cámara (5) a través de una escotadura (50) de la pared (8), estando la superficie de encendido (26) del electrodo de masa (4) al nivel de altura de la superficie de encendido (12) del electrodo central (3) dentro de la cámara (5), caracterizada por que el portaelectrodos de masa (6), visto en perpendicular al eje longitudinal (A) de la bujía (2), presenta una mayor distancia con respecto al electrodo central (3) que la superficie exterior (7) de la pared (8) de la cámara (5).
