Abstract

a presente invenção refere-se a um método e sistema para detectar vazamento de um arranjo de recirculação de gás de exaustão (30) em um sistema de motor (10) compreendendo um motor de combustão interna (2), um coletor de admissão (12) conduzindo aos cilindros do motor de combustão interna (2), um regulador de admissão (14) para ajustar o fluxo de ar para dentro do coletor de admissão (12), e um tubo de exaustão (16) para o gás de exaustão do motor de combustão interna (2). o arranjo de recirculação de gás de exaustão (30) compreende um tubo rge (32) e uma válvula rge (34). os gases de exaustão podem ser recirculados do tubo de exaustão (16), através do tubo rge (32) e da válvula rge (34), para o coletor de admissão (12) a jusante do regulador de admissão (14). a válvula rge (34) ajusta o fluxo de gás rge. o método compreende as etapas de: a) determinar se o motor de combustão interna (2) está em um estado ocioso e a válvula rge (34) está em uma posição fechada e, se assim; b) determinar a pressão absoluta do coletor de admissão (pim); c) determinar o grau de abertura do regulador de admissão (o); e d) determinar se a válvula rge (34) está vazando com base na correlação entre a pressão absoluta do coletor de admissão (pim) e o grau de abertura do regulador de admissão (o).
