Abstract

Un sistema de control de emisión de evaporación (10) de un motor turbocargado (11). El sistema de control de emisión de evaporación (10) incluye un depósito de vapor del combustible (18) en comunicación de fluidos con un múltiple de entrada (22) del motor turbocargado (11), una válvula de purga (26) colocada entre el múltiple de entrada (22) y el depósito de vapor del combustible (18), una válvula de derivación (38) colocada entre la válvula de purga (26) y el depósito de vapor del combustible (18) y conectada a la atmósfera, y un monitor de integridad del sistema de evaporación (10) que opera para sellar el depósito (18) de la atmósfera, cuando el motor (11) está apagado. En la operación, el monitor de integridad del sistema de evaporación (10) se cierra para sellar de esta forma el depósito de vapor del combustible (18) de la atmósfera, se cierra la válvula de purga (26) para aislar de esta forma el múltiple de entrada (22) del depósito de vapor del combustible (18), y se abre la válvula de derivación (38) para conectar el depósito de vapor del combustible (18) a la atmósfera. Se determina la operación adecuada del monitor de integridad del sistema de evaporación, si el monitor de integridad del sistema de evaporación cambia de cerrado a abierto cuando un vacío en el depósito de vapor del combustible (18) alcanza un nivel predeterminado.
