Abstract

MÉTODO PARA DETERMINAR A COMPOSIÇÃO DO COMBUSTÍVEL USADA PARA OPERAR UM MOTOR DE COMBUSTÃO INTERNA. A presente invenção refere-se a um método de acordo com a presente invenção, oscilações de pressão dinâmica no trato de entrada do respectivo motor de combustão interna são medidas durante a operação normal, e a partir das referidas, um sinal de oscilação de pressão correspondente é gerado. Ao mesmo tempo, um sinal do ângulo de fase do eixo de manivela é determinado. A partir do sinal de oscilação de pressão, a posição de fase atual da frequência de sinal selecionada das oscilações de pressão medidas em relação ao sinal do ângulo de fase do eixo de manivela é determinada, e a composição do combustível atualmente usada é determinada com base na posição de fase determinada atual levando em conta as posições de fase de referência de mesma frequência de sinal para diferentes composições de combustíveis.
