Abstract

Un sistema de inyección de combustible de línea de escape (1) y métodos de operación y control asociados se divulgan. El combustible pasa a través de una válvula reguladora (11, 60, 70, 80) teniendo una entrada (62, 81) conectada a una fuente de combustible presurizado (20) y una salida (63, 82) conectada a una línea de suministro de combustible del sistema de escape (15). L línea de suministro de combustible del sistema de escape () se conecta a una boquilla (12, 40, 50, 60), la cual generalmente comprende una válvula anti-retorno y se configura para inyectar al combustible dentro de la línea de escape (30, 100). Usando un dispositivo medidor de presión (13), una indicación de la presión de la línea de suministro de combustible del sistema de escape se obtiene. Un controlador (14, 119) proporciona control sobre la válvula reguladora de flujo (11, 60, 70, 80) usando retroalimentación a partir de la indicación de presión y una relación predeterminada entre la tasa de flujo a través de la boquilla (12, 40, 50, 60) y una de la presión de la línea de suministro de combustible del sistema de escape y la caída de presión a través de la boquilla (12, 40, 50, 60). El método se puede implementar con un solo dispositivo medidor de presión (13). Las mismas mediciones de presión, especialmente su espectro de frecuencias, pueden usarse para detectar fallas del sistema.
