Abstract

"PROCESSO DE DETERMINAçãO EM TEMPO REAL DA CARACTERìSTICA DE VAZãO DE INJETOR DE COMBUSTìVEL". O processo compreende etapas consistindo em considerar que o ganho de pelo menos um injetor (2) é igual a um ganho teórico ou atualizado, e em substituir cada uma de pelo menos uma injeção de referência, de uma duração de comando de injeção comandada pela unidade (5) de controle motor de acordo com uma característica memorizada, por uma injeção múltipla comportando uma sucessão de pelo menos duas injeções cujas durações de comando de injeção supostamente provocam a injeção da mesma massa de combustível que a injeção de referência substituída, em determinar a variação de massa de combustível entre a injeção de referência e a injeção múltipla, em deduzir um erro de determinação da característica, e em modificar o ganho e/ou o offset da zona linear da característica inicial ou pelo menos um quadro ou relação matemática da zona não linear desta característica, de sorte a compensar o erro, e em memorizar a nova característica assim determinada. Aplicações na determinação em tempo real, e em função da duração de comando de injeção, da característica de vazão dos injetores de combustível para motores de combustão interna alimentados por injeção.
