Abstract
PROCEDIMIENTO PARA LA REGULACION LAMBDA CONSTANTE DE UN MOTOR DE COMBUSTION (13) CON CATALIZADOR, EN EL QUE SE GENERA, AL MENOS EN ESTADOS DE FUNCIONAMIENTO PREDETERMINADOS, UNA OSCILACION DE LA REGULACION (FS) DE AMPLITUD PREDETERMINADA. ESTE PROCEDIMIENTO SE BASA EN EL CONOCIMIENTO DE QUE CON LA ELEVACION DE LA AMPLITUD DE LA OSCILACION DE LA REGULACION, SE ENSANCHA LA VENTANA DE CONVERSION, EN TANTO QUE NO SE EXCEDA UNA AMPLITUD MAXIMA. LA VENTANA DE CONVERSION ES AQUELLA GAMA DE VALORES LAMBDA, EN LA QUE LA CONVERSION PRESENTA AL MENOS UNA CALIDAD PREDETERMINADA.
