Abstract
La presente invención se refiere a un método para controlar la inyección del combustible directamente adentro de la cámara de combustión de un motor; el método está caracterizado porque comprende la inyección de una cantidad dosificada de combustible al interior de la cámara de combustión mediante una carga de gas a una de presión mayor que la presión atmosférica, y el control de la sincronización de la inyección del combustible en relación con el ciclo de la cámara de combustión, mediante lo cual; (i) se ajusta previamente la sincronización de la inyección del combustible cuando el motor está inactivo o marcha lenta; (ii) se ajusta la sincronización de la inyección al inicio del arranque del motor para que se efectúe la inyección en una sincronización preseleccionada anticipada en el ciclo de la cámara de combustión con respecto a la sincronización preajustada de inyección para la marcha lenta o inactiva; (iii) en respuesta a la condción en la cual el motor alcanza una velocidad predeterminada de rotación durante el arranque, la sincronización de la inyección se ajusta progresivamente en cada ciclo del motor hacia la sincronización de la inyección preajustada para la marcha lenta o inactiva durante un intervalo de tiempo de aproximadamente entre 0.2 y 1.0 segundos, comenzando desde que el motor alcanza dicha velocidad predeterminada; (iv) después se ajusta la sincronización de la inyección de acuerdo con la velocidad y/o la carga del motor.
