Abstract

PROCESSO PARA A DETERMINAÇçO DA COMPOSIÇçO DE UMA MISTURA DE COMBUSTÍVEL. A presente invenção refere-se a um processo para a determinação da composição de uma mistura de combustível, de um primeiro e pelo menos um segundo combustível, para a operação de uma máquina de combustão interna com pelo menos uma câmara de combustão, sendo que o primeiro e o segundo combustível apresentam pontos de ebulição diferentes e/ou entalpias de evaporação diferentes. Neste caso está previsto que a composição da mistura de combustível é averiguada baseada na pressão dentro da câmara de combustão e/ou em um parâmetro coerente à pressão e/ou baseado no decurso temporal da pressão e/ou no decurso temporal de um parâmetro coerente à pressão, durante e/ou depois de uma injeção do combustível durante uma fase de compressão da mistura de ar e de combustível. É vantajoso no processo de acordo com a invenção, que por meio deste já durante um primeiro procedimento de partida depois de um abastecimento, pode ser determinada a proporção de mistura do combustível, a qual se ajustou através do processo de abastecimento.
