Abstract

MÉTODO PARA REGULAR UMA RAZÃO ARCOMBUSTÍVEL E PARA RECONHECER UMA QUALIDADE DE COMBUSTÍVEL. A presente invenção refere-se a um método para regular uma razão ar/combustível e a um método para reconhecer uma qualidade de combustível, em que um sensor lambda (42) é fornecido no escapamento do motor de combustão interna, em que após o enchimento do tanque, o segundo valor de adaptação é primeiramente ajustado devido a um desvio do sinal lambda em relação ao sinal-alvo que ocorre de tal modo que a o sinal lambda oscile novamente em torno do valor-alvo, e em que o segundo valor de adaptação é determinado como uma função do valor de adaptação atual e como uma função da qualidade do combustível determinada no momento. A invenção refere-se ainda a um método para reconhecer uma qualidade de combustível, em particular uma razão de mistura de dois tipos de combustível, em que o sinal lambda do sensor lambda (42) é analisado para que seja efetuado o reconhecimento da qualidade.
