Abstract

<B>MéTODO DE CONTROLE AUTO-ADAPTATIVO DA TAXA DE MISTURA DE UM SISTEMA DE INJEçãO DE MOTOR DE COMBUSTãO INTERNA<D> referente a um método auto-adaptável de controle da razão de mistura de um sistema 2 de injeção, de um motor 4 de combustão interna, tendo um número de injetores 18, cada um para injetar uma respectiva quantidade operativa QF de combustível em cada ciclo do motor; e um sensor 12 de composição estequiométrica gerando um sinal de composição V relativo à composição estequiométrica dos gases de exaustão produzidos pelo motor 4. Em cada estado de operação do motor 4 e para cada injetor 18, o método executa as etapas de : determinar uma quantidade nominal QA de combustível a ser injetada como uma função de um número de parâmetros do motor medidos sobre o motor 4, e como uma função de um número de parâmetros de operação; determinar um parâmetro de operação KO2 como uma função do sinal de composição V e de uma função de regulagem proporcional-integral; determinar um coeficiente de correção quente KC indicando uma correção a ser feita na quantidade nominal QA de combustível para levar em conta o efeito na injeção de dispersões do motor 4 e do sistema de injeção 2 sob as temperaturas normais de operação do motor 4 atingidas; determinar um coeficiente de correção frio KF indicando uma correção a ser feita na quantidade nominal QA de combustível para levar em conta o efeito de baixas temperaturas de injeção; e determinar a quantidade operacional QF de combustível a ser injetada como uma função da quantidade nominal QA do parâmetro de operação KO2, do coeficiente de correção quente KC, e do coeficiente de correção frio KF - fig. 1.
