Abstract

UN MOTOR DE COMBUSTION INTERNA 2 TIENE UNA UNIDAD DE MOTOR 4 ALIMENTADA POR GAS COMBUSTIBLE A TRAVES DE UN CARBURADOR 20, Y TAMBIEN UN TUBO DE ESCAPE 6 QUE COMPRENDE UN CONVERTIDOR CATALITICO 8 Y UN SENSOR DE OXIGENO O PILA LAMBDA 10 DE CIRCONIO QUE INCORPORA UN CALENTADOR DE RESISTENCIA ELECTRICA DE PLATINO 16 EN UN CIRCUITO EN PUENTE 32 QUE TIENE UNA RESISTENCIA DE CONTROL 40 Y RESISTENCIAS FIJAS 36 Y 38. PARA CALIBRACION LA PILA 10 ES INICIALMENTE OPERADA EN UN AIRE ATMOSFERICO CON UN CIRCUITO DE CONTROL DE POTENCIA DE CALENTADOR 44 QUE SUMINISTRA UNA SALIDA DE CORRIENTE CONTINUA VARIABLE, BAJO CONTROL DE UN MICROCONTROLADOR 42, AL PUENTE PARA ACTIVAR EL CALENTADOR 16 Y VARIAR LA TEMPERATURA DE LA PILA 10. CUANDO LA PILA PROPORCIONA UNA SALIDA ELECTRICA DE UN VALOR DE REFERENCIA PREDETERMINADO EN LA TRAYECTORIA DE LA SEÑAL 12 ESTO ES OBSERVADO POR EL MICROCONTROLADOR 42 QUE VARIA EL VALOR DE LA RESISTENCIA DE CONTROL 40 A UN VALOR DE CALIBRACION RC2 EN EL QUE EL PUENTE 32 SE ANULA. A CONTINUACION, AL MICROCONTROLADOR 42 SE LE INDICA QUE ADOPTE EL MODO DE OPERACION Y DE ACUERDO CON SU PROGRAMA EL MICROCONTROLADOR ESTABLECE EL VALOR DE RESISTENCIA DE LA RESISTENCIA DE CONTROL 40 EN EL VALOR DE CONTROL RC1 PUESTO EN CORRELACION POR UNA FUNCION DE OPERACION EN EL PROGRAMA CON EL VALOR DE CALIBRACION RC2. LOS VALORES DE LAS RESISTENCIAS FIJAS 36 Y 38 SON RA Y RB RESPECTIVAMENTE. CUANDO LA PILA SE COLOCA EN EL TUBO DE ESCAPE Y SE OPERA EL CONTROL 14, EL CIRCUITO EN PUENTE 32 RECIBE CORRIENTE CONTINUA DEL CIRCUITO DE CONTROL 44 PARA ELEVAR LA TEMPERATURA DE LA PILA 10 HASTA QUE SE CUMPLA LA IGUALDAD RH/RC1 = RA/RB POR EL VALOR DE LA RESISTENCIA DEL CALENTADOR RH QUE VARIA CON LA TEMPERATURA. CUANDO SE CUMPLE LA IGUALDAD, EL CIRCUITO EN PUENTE 32 SE ANULA CUANDO LA RESISTENCIA DEL CALENTADOR RH TIENE EL VALOR RH1. ESTO ES OBSERVADO POR EL MICROCONTROLADOR 42 QUE VARIA LA SALIDA DE POTENCIA DEL CIRCUITO DE CONTROL 44 PARA MANTENER LA TEMPERATURA DE LA PILA LAMBDA SUSTANCIALMENTE CONSTANTE MEDIANTE EL MANTENIMIENTO DE LA RESISTENCIA DEL CALENTADOR EN SU VALOR RH1 PARA MANTENER LA NULIDAD DEL CIRCUITO EN PUENTE.
