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.FUEL CLASSIFICATION PROCESS IN DIRECT INJECTION INTERNAL FUEL ENGINES. The present invention relates to a process which is made available for the classification of fuels in direct injection internal combustion engines, especially diesel internal combustion engines. In this case at least one oxygen sensing element is used to determine the characteristic Lambda air value in the internal combustion engine exhaust gas. This process is characterized by the fact that the characteristic air value is measured at any point of engine operation by detecting at least one characteristic value of the engine operating point and with the aid of this characteristic air value. measured from a functional relationship characteristic of the previously determined engine operating fuel class and the characteristic air value is completed in the fuel class.
