Abstract

resumo patente de invenção: "método para se detectar descarga de combustível do óleo". a presente invenção refere-se a um método para se detectar descarga de combustível de um lubrificante que fica localizado em um alojamento de um motor de combustão interna. primeiramente, um primeiro desvio lambda é medido por meio de um sensor de lambda para um primeiro fluxo de massa de ar (ms1) provido em um duto de admissão do motor de combustão interna. adicionalmente, um segundo desvio lambda é medido por meio do dito sensor de lambda para um segundo fluxo de massa de ar (ms2) o qual difere do dito primeiro fluxo de massa de ar (ms1) e é provido em um duto de admissão do motor de combustão interna. um valor comparativo real é, então, calculado a partir do primeiro desvio lambda medido e do segundo desvio lambda medido. um valor comparativo desejado é calculado a partir de um primeiro desvio lambda desejado (ls1) para o primeiro fluxo de massa de ar (ms1), e um segundo desvio lambda desejado (ls2) é calculado para o segundo fluxo de massa de ar (ms2). o valor comparativo desejado é indicativo da descarga de combustível. a descarga de combustível é detectada com base em uma comparação do valor comparativo real e o valor comparativo desejado.
