Abstract

SE PRESENTA UN DISPOSITIVO DE DOSIFICACION DE COMBUSTIBLE PARA DISPOSITIVOS PARA LA INYECCION DIRECTA DE COMBUSTIBLE NEUMATICAMENTE ASISTIDA AL INTERIOR DE LA CULATA DE UN MOTOR DE COMBUSTION INTERNA (12) QUE ESTA PROVISTO DE UNA CAMARA (19) QUE ALOJA UNA VARILLA DE CONEXION (23) PARA ACCIONAR UN PISTON DE COMPRESION (24) DESLIZANTEMENTE GUIADA DENTRO DE UNA CAMISA (25) PROVISTA DE UNO O MAS CONDUCTOS DE TRANSFERENCIA (26) QUE CONECTAN LA CAMARA INTERNA (19) CON UN ESPACIO DE DIMENSION VARIABLE (27) POSICIONADO CORRIENTE ABAJO DEL PISTON (24) Y CORRIENTE ARRIBA DE UNA VALVULA (28) QUE SUMINISTRA ACCESO A LA CAMARA DE COMBUSTION (29), UNOS MEDIOS DE SUMINISTRO DE COMBUSTIBLE (31, 33, 35) ESTAN CONECTADOS AL ESPACIO DE DIMENSION VARIABLE. DE ESTA MANERA SE CONSIGUE UNA SOBREALIMENTACION MUY RAPIDA DURANTE LA ACELERACION.
