Abstract
SISTEMAS E MÉTODOS PARA DETERMINAR VIRTUALMENTE A CONCENTRAÇÃO DE ENXOFRE NO COMBUSTÍVEL. Trata-se de um módulo de controle para um sistema de pós-tratamento que inclui um catalisador de redução catalítica seletiva (SCR) e um catalisador de oxidação que compreende um controlador configurado para ser operacionalmente acoplado ao sistema de pós-tratamento. O controlador é configurado para determinar uma eficiência de conversão catalítica de SCR real do catalisador de SCR. O controlador determina uma eficiência de conversão catalítica de SCR estimada com base em uma concentração de enxofre de teste selecionada pelo controlador. Em resposta à eficiência de conversão catalítica de SCR estimada estar dentro de uma faixa predefinida, o controlador define a concentração de enxofre de teste como uma concentração de enxofre determinada em um combustível fornecido ao motor. O controlador gera um sinal de concentração de enxofre que indica o enxofre determinado.
