Abstract

PROCESSO PARA CLASSIFICAçãO DE COMBUSTìVEIS EM MOTORES DE COMBUSTãO INTERNA DE INJEçãO DIRETA. A presente invenção refere-se a um processo que é colocado à disposição para a classificação de combustíveis em motores de combustão interna de injeção direta, especialmente motores de combustão interna a diesel. Neste caso é utilizado, pelo menos, um elemento sensor de oxigênio para a determinação do valor característico de ar Lambda no gás de exaustão do motor de combustão interna. Este processo é caracterizado pelo fato de que o valor característico de ar é medido em um ponto qualquer de operação do motor por meio da detecção de, pelo menos, um valor característico do ponto de operação do motor e com o auxílio deste valor característico de ar medido a partir de uma relação funcional característica da classe de combustível de operação do motor anteriormente determinada e o valor característico de ar seja concluída a classe de combustível.
