Abstract

PROCEDIMIENTO PARA REGULAR LA COMPOSICION DE LA MEZCLA COMBUSTIBLE-AIRE DE UNA MAQUINA DE COMBUSTION INTERNA. COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE APLICA UNA SONDA DE OXIGENO EN LA TUBERIA DE GASES DE ESCAPE DE LA MAQUINA DE COMBUSTION INTERNA; SEGUNDA, A LA TENSION DE SALIDA DE DICHA SONDA SE LE CONECTA EN OPOSICION UNA TENSION DE REFERENCIA CONSTANTE, A TRAVES DE UNA RESISTENCIA FIJA, DETERMINANDOSE A PARTIR DE LA TENSION DE SALIDA RESULTANTE Y POR COMPARACION CON TENSIONES DE UMBRAL, LA DISPOSICION DE SERVICIO DE LA SONDA DE OXIGENO Y EL CONTENIDO EN OXIGENO EN LOS GASES DE ESCAPE; Y POR ULTIMO, SE INFLUYE SOBRE LA COMPOSICION DE LA MEZCLA COMBUSTIBLE-AIRE, APORTADA A LA MAQUINA DE COMBUSTION INTERNA, EN FUNCION DE LOS RESULTADOS DE LA COMPARACION EFECTUADA. LA TENSION DE REFERENCIA CONSTANTE SE ELIGE POR LO MENOS DE UNA MAGNITUD DOBLE QUE LA TENSION DE SALIDA MAXIMA DE LA SONDA DE OXIGENO CALIENTE A LA TEMPERATURA DE TRABAJO.
