Abstract

método para controlar um circuito egr de um motor de veículo a motor, válvula para implementação do dito método, e motor possuindo a dita válvula a invenção refere-se a um método para o controle de um circuito de recirculação de gás de exaustão (2c) para um motor de combustão interna (m) de um veículo a motor. o motor (m) é conectado a um circuito de entrada de ar (2a) e a um circuito de exaustão de gás (2b) conectado ao circuito de entrada de ar (2a) pelo circuito de recirculação (2c). uma primeira válvula (15) controla o fluxo de gases de exaustão que são recirculados dentro do circuito de recirculação (2c). no método da invenção, a recirculação dos gases de exaustão é em particular controlada por meio de medição de uma diferença de pressão através dos terminais da segunda válvula (16). o método compreende as etapas seguintes: a) as primeira e segunda válvulas (15, 16) são encerradas, a primeira válvula (15) sendo disposta de modo a permitir, em uma posição fechada, a passagem de uma corrente de vazamento de ar; b) as primeira e segunda vállvulas (15, 16) são concomitantemente abertas de modo a fornecer uma diferença de pressão suficiente através dos terminais da segunda válvula (16) de modo a permitir a medição da diferença de pressão nos terminais. devido à invenção, a diferença de de pressão através dos terminais da segunda válvula (16) permanece suficientemente alta de modo a permitir a medição eficiente da dita diferença de pressão.
