Abstract

Un método para hacer variar la concentración relativa de compuestos NO2 a NO formados en el cilindro de un motor que funciona con combustible diesel sin reducir sustancialmente la potencia del motor, comprendiendo el método: (a) determinar, en uno o más puntos de funcionamiento preseleccionados del motor, una magnitud de calibración de un hidrocarburo y un valor del ángulo de cig¿ ueñal para calibración para inyectar el hidrocarburo en el cilindro del motor diesel durante una carrera de expansión, después de la inyección de una carga primaria de combustible en el cilindro del motor durante una carrera de admisión, de modo que se obtenga una relación de NO2 a NO deseada en la corriente de escape del motor; y luego, durante el funcionamiento del motor (b) medir el punto de funcionamiento del motor; (c) determinar un valor del ángulo del cig¿ uenal y una cantidad de hidrocarburo para inyección durante la carrera de expansión después de la inyección de la carga de combustible primaria durante la carrera de admisión en el punto de funcionamiento medido a partir de los valores del ángulo de cig¿ uenal para calibración y de las cantidades de hidrocarburo para calibración en los puntos de funcionamiento preseleccionados cuando el punto de funcionamiento medido es el mismo que uno de los puntos de funcionamiento predeterminados y, cuando el punto de funcionamiento medido es diferente de los puntos de funcionamiento predeterminados, determinar la cantidad de hidrocarburo y elángulo del cig¿ uenal para inyección durante la carrera de expansión por interpolación entre los valores del ángulo de cig¿ uenal para calibración y las cantidades de hidrocarburo para calibración en los puntos de funcionamiento predeterminados; (d) inyectar la cantidad de hidrocarburo en el cilindro del motor durante la carrera de expansión al alcanzarse el ángulo de cig¿ uenal; (e) repetir los pasos (c) y (d) siempre que cambie el punto de funcionamiento del paso (b).
