Abstract

Motor de C.i. con emisión controlada e inyección directa tiene una cavidad de descarga del inyector de fuel que se reduce en anchura hacia el eje del cilindro. El motor, que tiene un cilindro limitado en el techo por la cabeza del cilindro, al menos un conducto de entrada y un conducto de salida conectada al cilindro a través de válvulas (26, 30) en la cara inferior de la cabeza del cilindro, tiene un inyector de fuel (42) que se dirige hacia el interior del cilindro mediante una cavidad de descarga (48) de reducido ancho hacia el centro del cilindro. La cavidad de descarga descansa sobre una tangente a un plano perpendicular al eje de los cilindros y con la cavidad que se extiende por debajo del anteriormente mencionado plano. La bujía del cilindro se sitúa en el centro de la cara inferior de la cabeza del cilindro.
