Abstract

Un sistema de control de inyección de combustible para un motor diesel, el cual tiene un inyector de combustible (5) para pulverizar directamente el combustible en una cámara de combustión (4) en un cilindro (2) del motor (1), estando controlado el inyector de combustible (5) para pulverizar el combustible al menos en un punto en el tiempo próximo al punto muerto superior de la carrera de compresión del cilindro (2), que comprende: un controlador de inyección dividida (35a) para dividir una inyección primaria del combustible mediante el inyector de combustible (5) cerca del punto muerto superior de la carrera de compresión del cilindro (2) en una pluralidad de inyecciones divididas, en la que una inyección dividida está seguida por la siguiente inyección dividida después de un intervalo de inter-emisión de inyección, el cual es un periodo que dura hasta que el inyector de combustible (5) se abre a continuación del siguiente cierre del mismo; caracterizado porque: tiene un dispositivo estimador (35b) para estimar que el instante de ejecución de la inyección dividida final de la inyección primaria sea posterior al punto en el tiempo correspondiente a un ángulo especificado del cigüeñal; y un corrector (353c) para corregir un modo de la inyección de combustible mediante el controlador de inyección dividida (35a) cuando el dispositivo estimador (35b) estime que el instante de ejecución de la inyección primaria sea posterior al punto en el tiempo correspondiente al ángulo especificado del cigüeñal.
