Abstract

VALVULA DE ADMISION MEJORADA (50) PARA UN MOTOR DE COMBUSTION INTERNA. TIENE UN RESALTE (62) QUE VA DESDE EL LADO INTERIOR DE LA PERIFERIA (64) DE LA CABEZA DE LA VALVULA (56) PARA AUXILIAR EN LA CREACION DE UN FLUJO AERODINAMICO DE LA MEZCLA GASEOSA COMBUSTIBLE/AIRE A TRAVES DE UNA ABERTURA DE LA VALVULA. EL RESALTE (62) ACTUA COMO LA PARTE MEDIA DE UN ALA SUSTENTADORA IDEAL REDUCIENDO ASI LA CONTRAPRESION E, IGUALMENTE, LA RESISTENCIA PRESENTADA POR LA VALVULA (50) A LA MEZCLA GASEOSA COMBUSTIBLE/AIRE. EL TAMAÑO DEL REBORDE (62) ES ENTRE EL 5 Y EL 25% DEL DIAMETRO DE LA CABEZA DE LA VALVULA (56) Y EL GROSOR DE LA PARED DEL REBORDE TAN ESTRECHO COMO PERMITE EL FUNCIONAMIENTO A LARGO PLAZO. EL REBORDE DE LA PARTE INFERIOR DE LA CABEZA DE LA VALVULA ES MENOS EFICIENTE, DESDE EL PUNTO DE VISTA DEL FLUJO, EN EL SENTIDO INVERSO, POSIBILITANDO UNA MEJOR SINCRONIZACION DE LA VALVULA Y SOLAPAMIENTOS DE CICLO.
