Abstract

PROCESSO PARA CONSIDERAçãO DA EXALAçãO DE COMBUSTìVEL DO óLEO DE MOTOR DE UM MOTOR DE COMBUSTãO INTERNA. A presente invenção refere-se a um processo para operação de um motor de combustão interna com uma lubrificação com óleo de motor, sendo que um fluxo de, massa de combustível exalando do óleo do motor é determinado e levando em consideração através de um pré-comando quando da dosagem de uma quantidade de combustível aduzida ao motor de combustão interna e sendo que é determinada uma relação combustível-ar aduzida ao motor de combustão interna. No processo segundo a invenção, quando da dosagem da quantidade de combustível aduzida ao motor de combustão interna durante uma duração eficaz do pré-comando, é levado em consideração um desvio da relação de combustível-ar aduzida ao motor de combustão interna de um valor teórico determinado 'offset" de fluxo de massa. O "offset" de fluxo de massa leva em consideração o desvio restante após a correção da quantidade de combustível dosada por um pré-comando à base do modelo de exalação de combustível do óleo do motor e alivia assim o regulador lâmbda. O "offset" de fluxo de massa pode, por exemplo, atuar encurtando a duração de injeção. Os desvios de mistura por distintas curvas de ebulição dos componentes da mistura de combustível, que não podem ser considerados plenamente sob todas as condições operacionais do motor de combustão interna pelo pré-comando, podem assim ser compensados.
