Abstract

UN MOTOR DE ENCENDIDO DE INYECCION DIRECTA INCLUYE UN INYECTOR DISPUESTO EN UNA PARTE PERIFERICA DE UNA CAMARA DE COMBUSTION CON UN TECHO DEL TIPO DE CUBIERTA EN PENDIENTE, CON UNA LINEA DEL EJE DE INYECCION DE COMBUSTIBLE OBLICUA RESPECTO A UNA LINEA DEL EJE DE LOS CILINDROS, UN PISTON CON UNA SUPERFICIE SUPERIOR DE FORMA COMPLEMENTARIA AL TECHO EN PENDIENTE DE LA CAMARA DE COMBUSTION, UNA CAMARA FORMADA EN LA SUPERFICIE SUPERIOR DEL PISTON, QUE TIENE UNA LINEA CENTRAL DE LA CAVIDAD PERPENDICULAR A LA LINEA DEL EJE DE INYECCION Y DESVIADA DE UN CENTRO DEL PISTON EN DIRECCION AL INYECTOR, EN UNA VISTA EN PLANTA, UNA BUJIA DE ENCENDIDO DISPUESTA PRACTICAMENTE EN EL EJE DEL CILINDRO DE LA CAMARA DE COMBUSTION, UN GENERADOR DE TORBELLINO QUE GENERA UN TORBELLINO EN LA CAMARA DE COMBUSTION, DE MANERA QUE EL COMBUSTIBLE SE INYECTE DESDE EL INYECTOR EN DIRECCION A LA CAVIDAD, PARA CONCENTRAR UNA MEZCLA DE COMBUSTION ALREDEDOR DE LA BUJIA DE ENCENDIDO, DETERMINANDOSE UNA DISTANCIA (D1) ENTRE LA LINEA DEL EJE DE INYECCION DE COMBUSTIBLE Y UN PUNTO (A) DE UNA PARTE DE PARED PERIFERICA DE LA CAVIDAD DE MANERA QUE SE CUMPLA LA RELACION SIGUIENTE: D1(LXTAN( ZE 0/2 + ZE 1) EN LA QUE A ES UN PUNTO CRUZADO DE UNA PARTE DE LA PARED PERIFERICA DE LA CAVIDAD EN UNA VISTA EN PLANTA DE LA SUPERFICIE SUPERIOR DEL PISTON, EN UN LADO AL QUE SE DESVIA EL COMBUSTIBLE INYECTADO GRACIAS AL TORBELLINO, ZE 0: ANGULO DE PULVE RIZACION DEL COMBUSTIBLE INYECTADO EN LA CARRERA DE COMPRESION, ZE 1: EL VALOR MAXIMO DEL ANGULO DESVIADO DEL COMBUSTIBLE INYECTADO, L1: DISTANCIA ENTRE UNA BOQUILLA DEL INYECTOR Y LA LINEA CENTRAL DE LA CAVIDAD, DETERMINANDOSE UNA ALTURA H DE UNA PARED LATERAL DE LA CAVIDAD DE MANERA QUE SE CUMPLA LA SIGUIENTE RELACION, VISTA EN SECCION, PASANDO POR LA LINEA DEL EJE DE INYECCION DE COMBUSTIBLE Y EL EJE DEL CILINDRO, H >= HMIN EN LA QUE HMIN: LONGITUD A LO LARGO DE LA LINEA DEL EJE DEL CILINDRO DE UNA DISTANCIA ENTRE UN PUNTO DE EXTREMO DE LA PUNTA (C) Y UN PUNTO CRUZADO (D), C: UN PUNTO DEL EXTREMO DE LA PUNTA DE LA PARED LATERAL DE LA CAVIDAD POR EL QUE PASA LA LINEA SUPERIOR DE PULVERIZACION, D: UN PUNTO CRUZADO DE LA LINEA DEL EJE DE INYECCION DE COMBUSTIBLE CON UNA LINEA EN ANGULO RECTO A LA LINEA DE INYECCION DE COMBUSTIBLE Y QUE PASA POR EL PUNTO (C) DEL EXTREMO DE LA PUNTA, CUANDO UNA LINEA LIMITE DE LA PULVERIZACION SUPERIOR PASA POR EL PUNTO (C) DEL EXTREMO DE LA PUNTA DE LA PARED LATERAL DE LA CAVIDAD. SE PUEDE OBTENER UNA CONDICION ESTRATIFICADA PERFECCIONADA Y, EN CONSECUENCIA, MEJORARSE EL RENDIMIENTO DE LA COMBUSTION Y LA EFICIENCIA EN EL CONSUMO DE COMBUSTIBLE.
