Abstract

Un conjunto inyector de combustible para un motor diese1 locomotriz EMD 710 a base de emisiones. El conjunto inyector de combustible incluye una aguja que puede deslizarse y colocarse dentro de un orificio de un cuerpo de valvula en el conjunto inyector, en donde la presion de combustible introducida en la camara de orificio hace que la aguja abra una punta de rociado. Un resorte montado dentro del orificio forza a la aguja a cerrar la punta de rociado cuando el combustible no esta siendo aplicado. El resorte es un resorte de espiral inactiva incluyendo espirales no activas en donde por lo menos partes de las espirales en ambos extremos del resorte estan en contacto intimo unas con otras como para reducir el desgaste del resorte durante la operacion del conjunto. Debido a que el resorte de espiral inactivo tiene un desgaste reducido, el punto fijo de presion de abertura de valvula del conjunto inyector de combustible puede ser reducido, lo cual reduce las emisiones Nox.
