Abstract

PROCESSO PARA DETERMINAçãO DA COMPOSIçãO DE UMA MISTURA DE COMBUSTìVEL. A presente invenção refere-se a um processo para a determinação da contaminação de uma mistura de combustível consistindo em um primeiro e em ao menos um segundo combustível para operação de um motor de combustão interna com ao menos uma câmara de combustão, sendo que misturas de combustível de diferente composição são queimadas a distintos ângulos de ignição ZW~ máx.~ ótimos com ótimo rendimento. Para tanto, o ângulo de ignição ZW do motor de combustão interna é alterado, o rendi- mento <sym> do motor de combustão interna ou uma grandeza característica disso dependente é determinado em função do ângulo de ignição ZW e da alteração do rendimento <30><sym> ou da grandeza característica disso dependente quando da alteração do ângulo de ignição ZW e/ou do ângulo de ignição ZW em função do rendimento <30><sym> ou da grandeza característica dependendo do rendimento <sym> é determinada a composição da mistura de combustível. O processo possibilita determinar a relação de mistura de combustível no tanque de motores de combustão, que podem ser operados com diversos combustíveis.
