Abstract

"MéTODO PARA ESTIMAR A QUANTIDADE DE AR FRESCO PRESENTE NOS CONDUTORES DE ENTRADA E DE EXAUSTãO DE UM MOTOR A COMBUSTãO INTERNA COM UM CIRCUITO DE RECIRCULAçãO". Um método de estimativa da quantidade de ar fresco (M~ aira~), (M~ airs~) presente nos condutores de entrada e de exaustão (3), (5) de um motor a combustão interna (1) com um circuito de recirculação (9), (10) por um observador (O), aplicado a um sistema (S) da terceira ordem, que modela o sistema físico constituído pelos condutores de entrada e de exaustão (3), (5); com o sistema (S) sendo obtido a partir de equações diferenciais, que regulam os processos de mistura dos gases, e de uma equação que representa o comportamento de um sensor lambda (13).
