Abstract

sistema, método e aparelho para monitorar sistema pós-tratamento trata-se de um método que inclui determinar se é detectado um evento de recarga de uréia, e limpar uma quantidade de valor acumulador de qualidade e limpar um comando de travamento de aborto. o método inclui determinar se condições de aborto de verificação de qualidade do fluido de uréia são atendidas, e limpar o acumulador de qualidade de uréia, travar o comando de aborto, e sair da verificação de qualidade de fluido redutor. em resposta às condições de aborto não sendo atendidas, incrementar o acumulador de qualidade de uréia de acordo com uma quantidade de uréia sendo injetada, e comparar a quantidade de uréia acumulada e um limiar de teste baixo. o método inclui, em resposta à quantidade de uréia acumulada sendo maior do que a limiar baixo de teste, comparar a quantidade de uréia acumulada a um limiar alto de teste, e em resposta à quantidade de uréia sendo maior do que o limiar de teste alto, determinar se é observada a excedência de no~ x~ e limpar um erro de qualidade de uréia em resposta à excendência no~ x~ não sendo observada.
