Abstract

PROPONEMOS EL PROCESO Y DISPOSITIVO PARA SU REALIZACION, EN EL QUE EL CONCEPTO BASICO CONSISTE EN DIAGNOSTICAR LA DISPOSICION DEL CALOR DE UN GAS DE ESCAPE QUE EMITE UNA SEÑAL DE CONTROL PARA REGULAR EL AIRE/MEZCLA DE FUEL-OIL EN UN MOTOR DE COMBUSTION INTERNA. EL DIAGNOSTICO SE BASA EN EL HECHO DE QUE, AL ENCENDER LA CALEFACCION, QUE CONSTA DE UN MINIMO DE UNA SONDA DE CALEFACTOR, DISPOSITIVOS QUE SUMINISTRAN EL CALOR DE LA SONDA CON LA POTENCIA ELECTRICA NECESARIA Y LINEAS DE SUMINISTRO ADECUADAS, LA SONDA DE GAS DE ESCAPE SE CALIENTA MAS RAPIDAMENTE QUE SI LOS GASES DE ESCAPE FLUYERAN SIMPLEMENTE A SU ALREDEDOR.
