Abstract

CUANDO UN APARATO PARA EL SUMINISTRO DE ENERGIA A UN EHC FALLA, EL SUMINISTRO DE ENERGIA AL EHC ES CORTADO POR UN MEDIO QUE ESTA SEPARADO DEL RELE DE CONTROL PARA EVITAR QUE SE SOBRECALIENTE EL CATALIZADOR. EL RELE DE CONTROL QUE ES ABIERTO Y CERRADO POR UN ECU ESTA DISPUESTO EN UN CIRCUITO QUE SUMINISTRA ENERGIA ELECTRICA DESDE UNA FUENTE DE ENERGIA AL EHC SUJETO AL CONDUCTO PARA LOS GASES DE ESCAPE DE UN MOTOR DE COMBUSTION INTERNA, Y LA ENERGIA SUMINISTRADA AL EHC ES CONTROLADA POR EL RELE DE CONTROL. CUANDO EL RELE DE CONTROL ES CORTOCIRCUITADO, ESTE FALLO ES DETECTADO POR ALGUN MEDIO, Y EL CIRCUITO DE SUMINISTRO DE ENERGIA ES OBLIGADO A PARAR DE MANERA QUE LA ENERGIA NO SEGUIRA SIENDO SUMINISTRADA DE FORMA CONTINUA AL EHC DESDE LA FUENTE DE ENERGIA EN ESTE ESTADO. LOS MEDIOS PARA CORTAR EL CIRCUITO DE SUMINISTRO DE ENERGIA PUEDEN SER UN RELE, UN DISRRUPTOR O UN FUSIBLE CUANDO LA FUENTE DE ENERGIA ES UNA BATERIA, Y PUEDEN DISPONERSE PARA SUMINISTRAR LA CANTIDAD DE ENERGIA GENERADA POR UN ALTERNADOR CUANDO LA FUENTE DE ENERGIA ES EL ALTERNADOR.
