Abstract

1/1 resumo “método e sistema relativos ao monitoramento de emissões de partículas em exaustões de motor de combustão” a presente invenção se refere a um método para a determinação de emissões de partículas relativas a um motor de combustão, de tal modo que um sistema de pós-tratamento compreendendo pelo menos um filtro de partículas é proporcionado para pós-tratamento de um fluxo de exaustão resultante da combustão no referido motor. o método compreende -usar um sensor de pm situado a montante do referido filtro de partículas para determinar, em uma localização a montante do referido filtro de partículas, um primeiro teor de partículas do referido fluxo de exaustão proveniente do referido motor, e -usar o referido primeiro teor de partícula determinado como uma base para determinar se o teor de partículas do referido fluxo de exaustão a jusante do referido filtro de partículas satisfaz uma primeira condição. a invenção se refere também a um sistema e um veículo.
