Abstract

resumo ?processo de diagnóstico do funcionamento da válvula de purga de um filtro de vapores de combustível de um motor de combustão interna, e, motor de combustão interna? a invenção refere-se a um processo de diagnóstico do funcionamento da válvula de purga de um cânister de um motor de combustão interna, o referido processo, realizado durante uma purga, compreende as seguintes etapas: a) detecção, em um instante t0, que a válvula de purga está aberta, b) execução de um fechamento forçado da referida válvula em um instante t2, c) medição de uma pressão p1m do coletor de admissão e cálculo de uma pressão modelada p1c correspondente, em um instante t1 situado entre o instante t0 o instante t2, d) medição de uma pressão do coletor p2m e cálculo de uma pressão modelada p2c correspondente, em um instante t3 situado após o instante t2, e) cálculo de um desvio e1 entre p1m e p1c e cálculo de um desvio e2 entre p2m e p2c, f) cálculo de um critério c=e1-e2, g) diagnóstico de funcionamento defeituoso da referida válvula de purga, se o critério c for inferior a um valor limiar cs predeterminado.
