Abstract

PROCESSO PARA A DETERMINAÇçO DE UMA COMPOSIÇçO DO COMBUSTÍVEL. A presente invenção refere-se a um processo para a determinação da composição de um combustível com os componentes etanol e gasolina de uma máquina de combustão interna, na qual o combustível, através de uma alimentação de combustível, através de duas calhas de distribuição de combustível, é levado para a máquina de combustão interna, e o gás de escape da máquina de combustão interna, é removido através de dois bancos de gás de escape, separados um do outro, de um primeiro e um segundo que as mudanças atuais do teor de etanol no combustível são averiguadas, baseadas em diferenças de sinal, de sinais lambda, das sondas de gás de escape. Com este processo pode ser reconhecida uma mudança do teor de etanol no combustível, e ser deduzida uma condição inequívoca para uma mudança de combustível. Além disso, com o processo podem ser distinguidas falhas da mistura, de uma composição do combustível variada, depois de um abastecimento.
