Abstract

SE SUMINISTRA UN SISTEMA ELECTRONICO PARA EL CONTROL DE LA CONCENTRACION EN EL CUAL UN PRIMER SENSOR DE LA COMPOSICION DE LOS GASES DE ESCAPE (16) SITUADO EN UN TUBO DE ESCAPE (9) CORRIENTE ABAJO DE UN CONVERSOR CATALITICO (11) SE CONECTA A UNA ENTRADA A 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 DE ESCAPE (14) SITUADO EN EL TUBO DE ESCAPE (9) CORRIENTE ARRIBA DEL CONVERSOR CATALITICO (11) QUE GENERA UNA SEÑAL QUE ES SUMINISTRADA A UN CIRCUITO INTEGRAL PROPORCIONAL (30) CUYOS COEFICIENTES DE INTEGRACION Y DE MULTIPLICACION (KI, KP) ESTAN ALTERADOS SOBRE LA BASE DE LA SEÑAL DE CONTROL (K02).
