Abstract

Motor de combustión interna que comprende: - una cámara de combustión (1) delimitada por la pared superior de un pistón (3) montado dentro de un ánima cilíndrica (2) de un bloque de cilindros y la pared inferior de una culata (4) en forma de techo (13) cuya arista (14) se extiende paralelamente al eje longitudinal del motor; - dos conductos de admisión (5, 6) formado a través de la culata (4) y que desembocan en la cámara de combustión (1) en un lado de la superficie de techo (13) por dos orificios distintos de admisión (7, 8) obturados por válvulas; - dos conductos de escape (9, 10) formados a través de la culata (4) y que desembocan en la cámara de combustión (1) en el lado opuesto a los orificios de admisión por dos orificios distintos de escape (11, 12) obturados por válvulas; - un vaciado (18) previsto en la culata y que desemboca en la pared inferior de la culata (4) en forma de techo (13); - un inyector de carburante (16) dispuesto paralelamente al eje del cilindro (2) y que desemboca en el vértice del vaciado (18); - una bugía de encendido (17) que desemboca en el vaciado (18); - estando formado el vaciado (18) por una cavidad principal (22) delimitada por un fondo (20) en el que desemboca la nariz del inyector (16) y una pared lateral (19), y una pluralidad de cavidades secundarias (21) que desembocan en la parte inferior de la cavidad principal (22).
