Abstract

İçten yanmalı motorlarda enjektörden yüksek miktarda yakıt püskürtülmesini sağlamak için enjektör eksenine göre memede üstüste yer alan iki sıra delikler ve bu deliklerin açılma ve kapanmasını ayrı ayrı kontrol eden bir dış iğne ve iç iğneden oluşan sistemler mevcuttur. Burada açıklanan buluşun amacı ise eşeksenli çift iğneli(5, 6) sistemi karmaşık olmayan basitleştirilmiş bir yapıya dönüştürmektir. Bu buluşta açıklanan sistemde eşeksenli iğnelerden dış iğne(5) bir yay(12) yardımıyla kumanda edilirken, iç iğne(6) iğnenin üzerinde bulunan hacmi(8) ana enjektör içindeki yakıt kanalına bağlayan(10) ve kısıcı etki yaratan ince kanallar(9) yoluyla kontrol edilmektedir. İstendiğinde iç iğnenin(6) kontrolü için iç iğnenin üzerinde yer alan hacme(8) ayrıca küçük bir yay(11) ilavesi de yapılabilir. Elde edilecek olan enjektör-meme sisteminin yapısı alışılagelen standart tek iğneli sistemlerle benzer olduğundan büyük bir değişiklik yapılmaksızın yaygın olarak kullanılması mümkün olacaktır.In order to ensure a high amount of fuel injection from the injector in internal combustion engines, there are systems consisting of two rows of holes located on top of the nozzle according to the injector axis, and an outer needle and an inner needle that separately control the opening and closing of these holes. The aim of the invention described here is to transform the coaxial twin needle (5, 6) system into an uncomplicated simplified structure. In the system described in the present invention, the outer needle (5) is controlled from the coaxial needles with the help of a spring (12), while the inner needle (6) connects the volume on the needle (8) to the fuel channel in the main injector (10) and creates a restrictive effect through thin channels (9). controlled via. If desired, a small spring (11) can also be added to the volume (8) located on the inner needle (6) for the control of the inner needle (6). Since the structure of the injector-nozzle system to be obtained is similar to the usual standard single-needle systems, it will be possible to use it widely without making any major changes.
