Abstract
EL DISPOSITIVO DE ALIMENTACION COMPRENDE INYECTORES (34), UNA CAJA ELECTRONICA DE MANDO DE LOS INYECTORES Y UNA VALVULA DE MARIPOSA (8). CADA INYECTOR LLEVA UN CUERPO PROVISTO DE MEDIOS DE FIJACION EN UN ALOJAMIENTO QUE DESEMBOCA EN LA TUBULADURA Y UN SALIENTE ATRAVESADO DE UN PASO DE SALIDA DEL COMBUSTIBLE, DELIMITANDO UNA CAMARA DE MEZCLA CONECTADA A UNA ENTRADA DE AIRE. EL DISPOSITIVO TIENE UN CONDUCTO DE AIRE ADICIONAL (18), CUYA ENTRADA ESTA SITUADA HACIA ARRIBA DE LA VALVULA DE MARIPOSA, DONDE EL CONSUMO ES REGULABLE POR UNA VALVULA DE SOLENOIDE (20) Y QUE CONDUCE EL AIRE QUE HA ATRAVESADO LA VALVULA DE SOLENOIDE DE AIRE ADICIONAL A LA CAMARA DE MEZCLA DE LOS INYECTORES Y A UNA ELECTROVALVULA SUPLEMENTARIA (74), QUE DESEMBOCA HACIA ABAJO DE LA VALVULA DE MARIPOSA (10).
