Abstract

a presente invenção refere-se a uma abertura básica (a0) de uma válvula de controle de egr (22) que é configurada, com base em um estado de operação atual do motor. o diferencial de pressão (¿p1) através da válvula de controle de egr (22) é calculado, com base na temperatura atual do sistema de escape (t1) lida por um sensor de temperatura de escape (33). o diferencial de pressão de referência (¿p1) é calculado, que é o diferencial de pressão através da válvula de controle de egr (22) em um estado estável que corresponde ao estado de operação atual do motor. a amplitude de pulsação de referência (d) é calculada, que é a amplitude de pulsação do diferencial de pressão de referência (¿p1). a abertura básica (a0) é corrigida, com base no diferencial de pressão (¿p1), no diferencial de pressão de referência (¿p0) e na amplitude de pulsação de referência (d).
