Abstract

Perfeccionamientos en motores de combustión interna de ciclo diesel, del tipo que comprenden una cámara de precombustión formada por una cavidad en un inserto metálico comportado por la cabeza del cilindro, cuya cavidad está cerrada por un extremo por el cuerpo del inyector, caracterizado porque la cámara de precombustión (6) está formada por dos partes (20, 24) la primera de las cuales (20) es de forma sustancialmente cilíndrica con una porción troncocónica (22) en el extremo corriente abajo y en donde comunica con la segunda parte (24) que es también de forma sustancialmente cilíndrica y que comunica con un conducto (8) para la descarga de gases producidos como resultado de la combustión de la cámara de precombustión (6).
