Abstract

PROCESSO PARA A CONSIDERAçãO DA EVAPORAçãO DE COMBUSTìVEL DO óLEO DO MOTOR DE UMA MáQUINA DE COMBUSTãO INTERNA. A presente invenção refere-se a um processo para o acionamento de uma máquina de combustão interna, com uma lubrificação com óleo do motor e uma alimentação de combustível através de injeção direta, sendo que, é determinado um coeficiente de ar lambda de uma mistura de ar e combustível conduzida à máquina de combustão interna. O processo de acordo com a invenção prevê que, mediante o reconhecimento de um coeficiente de ar lambda baixo em estados de operação com uma alta parte de entrada de combustível proveniente de uma retirada do ar da carcaça de manivelas, a máquina de combustão interna é conduzida para um estado de operação com consumo de combustível mais alto. Devido a esse aumento da demanda de combustível, o combustível proveniente do óleo do motor, introduzido na alimentação de ar da máquina de combustão interna, pode ser queimado, e pode ser evitado um aumento dos valores do gás de exaustão devido ao combustível queimado de modo incompleto, sendo que, tipicamente, se formam hidrocarbonetos e monóxido de carbono. Em uma fase de funcionamento a quente da máquina de combustão interna, assim, o combustível introduzido no óleo do motor pode ser queimado, embora sob certas condições de tempo e temperatura, em particular, na operação de carga parcial e na marcha em vazio, exista mais combustível na mistura de ar e combustível do que é propriamente necessário para a operação da máquina de combustão interna.
