Abstract

LOS DISPOSITIVOS DE INYECCION DE MEZCLA DE AIRE Y COMBUSTIBLE CONOCIDOS PUEDEN ADAPTARSE UNICAMENTE A CORRIENTES DE MASA DE AIRE SOLICITADAS INDIVIDUALMENTE DENTRO DE UNOS LIMITES Y CON UN COSTE ALTO. OTROS DISPOSITIVOS CON VALVULAS DE INYECCION ESTANDAR OCUPAN UN AMPLIO ESPACIO Y TIENEN UNA ESTRUCTURA COMPLEJA. UN NUEVO DISPOSITIVO TIENE LA VENTAJA DE SER UNA PIEZA PREFABRICADA QUE PUEDE UTILIZARSE CON VARIAS VALVULAS DE INYECCION DE COMBUSTIBLE SIN AJUSTES POSTERIORES. EL MANGUITO (4) QUE CONTIENE EL AIRE TIENE CARAS DE PARADA (26) QUE SE APOYAN EN EL EXTREMO DE INYECCION (6, 20) DE LA VALVULA DE INYECCION DE COMBUSTIBLE (1) Y FORMAN CON ESTA ULTIMA UNA SALIDA DE AIRE ESTRECHA (27), DE TAL FORMA QUE EL AIRE ES ACELERADO CASI A LA VELOCIDAD DEL SONIDO Y ATOMIZA FINAMENTE EL COMBUSTIBLE INYECTADO A TRAVES DE LAS ABERTURAS DE INYECCION DE COMBUSTIBLE (8). ESTE DISPOSITIVO DE INYECCION DE MEZCLA DE AIRE Y COMBUSTIBLE ES ESPECIALMENTE UTIL PARA INYECTAR LA MEZCLA EN EL DISTRIBUIDOR DE ENTRADADE UN MOTOR DE COMBUSTION INTERNA CON ENCENDIDO POR CHISPAS.
