Abstract
SE PRESENTA UN SISTEMA ELECTRONICO PARA EL CONTROL DE LA CONCENTRACION EN EL CUAL UN PRIMER SENSOR DE LA COMPOSICION DE UN GAS DE ESCAPE (16) SITUADO EN UN TUBO DE ESCAPE (9) CORRIENTE ABAJO DE UN CONVERSOR CATALITICO (11) ESTA CONECTADO A UNA ENTRADA DE UN CIRCUITO DE P.I. (28) QUE GENERA UNA SEÑAL DE SALIDA DE CONTROL (K02) QUE COMPRENDE UNA SUCESION DE RAMPAS TRIANGULARES OPUESTAS. EL SISTEMA INCLUYE UN SEGUNDO SENSOR DE LA COMPOSICION DEL GAS (14) SITUADO EN EL TUBO DE ESCAPE (9) CORRIENTE ARRIBA DEL CONVERSOR CATALITICO (11) QUE GENERA UNA SEÑAL QUE ES SUMINISTRADA A UN CIRCUITO PROPORCIONAL, INTEGRAL (30) CUYOS COEFICIENTES DE INTEGRACION Y DE MULTIPLICACION (KI, KP) SON ALTERADOS SOBRE LA BASE DE LA SEÑAL DE CONTROL (K02). EL SISTEMA INCLUYE UN CIRCUITO DE DIAGNOSTICO (50) QUE CHEQUEA LA EFICIENCIA DEL PRIMER Y DEL SEGUNDO SENSOR (16, 14).
