Abstract
LA INVENCION SE REFIERE A UN PROCESO PARA EL RECONOCIMIENTO DE SONDAS LAMBDA CONECTADAS EN DISPOSICION DE LADOS INVERTIDOS EN UN MOTOR DE COMBUSTION INTERNA CON DOS SERIES DE CILINDRO, QUE ESTAN COORDINADAS DE FORMA SEPARADA CON UN CATALIZADOR DE GAS DE ESCAPE, CON SONDA LAMBDA Y UNIDAD DE REGULACION LAMBDA CONECTADA CON ELLA, CUYAS VALVULAS DE INYECCION SON DESCONECTABLES AL MENOS EN DISPOSICION DE SERIE DE CILINDROS, DE FORMA QUE LAS VALVULAS DE INYECCION DE UNA DE AMBAS SERIES DE CILINDROS SE DESCONECTA EN AL MENOS UN TIEMPO DE CONMUTACION O DE REACCION DEL TIEMPO CORRESPONDIENTE DE SONDA LAMBDA. ADEMAS SE COMPARA LA SEÑAL DE SONDA LAMBDA DE LA SERIE DE CILINDROS DESCONECTADA CON LA SONDA LAMBDA COORDINADA EN EL EXTREMO DE ACUERDO CON EL TIEMPO DE DESCONEXION DE LA VALVULA DE INYECCION CON UN VALOR UMBRAL PREVIAMENTE DADO. FINALMENTE SE RECONOCE UNA CONEXION DE DISPOSICION DE LADOS INVERTIDOS DE LA SONDA LAMBDA, CUANDO LA SEÑAL DE LA SONDA LAMBDA SOBREPASA O ESTA POR DEBAJO DEL VALOR UMBRAL.
