Abstract

MéTODO DE CONTROLE DE OPERAçãO DE UM MOTOR QUE PODE USAR UM MODO DE COMBUSTãO DE COMBUSTìVEL úNICO OU MULTICOMBUSTìVEL. A presente invenção refere-se a um método de controlar a operação de um motor de combustão interna, usando um modo de combustão de combustível único ou multicombustível, com pelo menos um tipo de combustível compreendendo um alto número de octanas e uma baixa densidade de energia e pelo menos outro tipo de combustível compreendendo um baixo número de octanas e uma alta densidade de energia, um método no qual a energia necessária para o motor operar em modo multicombustível é proporcionada por uma combinação dos dois tipos de combustíveis. De acordo com a invenção, para operação do motor em modo multicombustível, o método consiste em: - determinar os valores de ajuste da densidade de energia global e do número de octanas global resultantes da combinação de combustíveis; - alimentar na câmara de combustão os ditos combustíveis, com uma proporção intencionada para atingir os valores de ajuste; - avaliar os valores reais da densidade de energia global e/ou do número de octanas global dos ditos combustíveis; e - no caso de uma diferença entre os valores de ajuste e valores reais, compensar esta diferença pela variação da proporção de pelo menos um dos combustíveis a fim de obter o conjunto de densidade de energia e/ou número de octanas.
