Abstract

Motor de combustión interna con inyección directa de combustible y encendido por chispa, en el que la cámara (1) de combustión está formada por un bloque de cilindros (2), una culata (3) y un pistón (4), en cuya superficie (5) de dicho pistón se encuentra conformada una cavidad (6) y se puede inyectar el combustible desde una tobera (7) de inyección en dirección hacia la cavidad (6) y se puede encender mediante un dispositivo (8) de encendido por chispa, y en el que la cavidad (6) se encuentra situada y conformada o dimensionada en el pistón (4) de tal forma que el dispositivo (8) de encendido por chispa o un portador del dispositivo (8) de encendido por chispa se introduce al menos por su extremo libre y con pequeña holgura en la cavidad (6) incluso antes de alcanzar el instante de encendido, y que en el momento de alcanzar el punto muerto superior del pistón (4) se encuentra introducido con pequeña holgura en la cavidad (6), rellenando así la cavidad (6) al menos en gran parte, caracterizado porque el dispositivo (8) de encendido por chispa o el portador del dispositivo (8) de encendido por chispa y la tobera (7) de inyección están asignados en posiciones fijas en el bloque de cilindros (2) como componentes independientes entre sí, y porque la tobera (7) de inyección está dispuesta y orientada de tal forma que el eje (35) del chorro de inyección está acodado respecto al eje del pistón.
