Abstract

Procedimiento y sistema de inyección de combustible para un motor de combustión interna, con al menos dos presiones de combustible de niveles diferentes, por medio de inyectores (8), en el recinto de combustión de un motor de combustión interna, almacenándose la presión más elevada del combustible en un acumulador central (6) de presión, generándose la presión más baja del combustible individualmente, de forma local, para cada inyector (8), en cualquier momento durante el proceso de inyección por medio de descarga de la presión más elevada del combustible, siendo activable o desactivable la descarga por medio de una válvula de pasos. Un sistema de inyección de combustible (1) correspondiente con un acumulador central (6) de presión para el almacenamiento de la presión más elevada del combustible presenta, a tal fin, para cada inyector (8), respectivamente, una unidad local de descarga (29), por medio de la cual se puede generar, por disipación, la presión más baja del combustible a partir de la presión más elevada del combustible, presentando la unidad local de descarga (28) una válvula de pasos (9) para la activación o desactivación de la descarga. De esta manera, se puede conseguir una dosificación mejorada de la presión más baja del combustible.
