Abstract

CIRCUITO DE CONEXION PARA UNA SONDA LAMBDA (SV, SH) Y PROCEDIMIENTO DE COMPROBACION PARA UN CIRCUITO DE ESTE TIPO, CON UNA LINEA DE MASA (ML_SV, ML_SH) Y UNA LINEA DE SEÑAL (SL_SV, SL_SH), QUE PRESENTA UNA FUENTE DE TENSION OFFSET (UOS) QUE ESTA ENLAZADA CON LA LINEA DE MASA CON EL FIN DE ELEVAR EL POTENCIAL DE LA MISMA A UN VALOR PREDETERMINADO CON RESPECTO A MASA. EN UN CIRCUITO DE CONEXION DE ESTE TIPO SE PUEDE DETECTAR DIRECTAMENTE UN CONTACTO A MASA PORQUE EL POTENCIAL MEDIDO EN LA LINEA DE SEÑAL CAE POR DEBAJO DE LA TENSION OFFSET. DE ESTE MODO PARA COMPROBAR UN CONTACTO A MASA YA NO ES NECESARIO, COMO EN LOS CIRCUITOS TRADICIONALES, EFECTUAR UN ENRIQUECIMIENTO DE LA MEZCLA PARA UN MOTOR, CUYO GAS DE ESCAPE SE VIGILA MEDIANTE LA SONDA LAMBDA.
