Abstract

Bu buluş içten yanmalı motorlarda yaygın olarak kullanılan enjektör sistemini enjektör memesinin üst gövde (7) kısmı ile püskürtme deliklerinin bulunduğu alt gövde (8) kısmını iki ayrı parça şeklinde yapmayı öngörmektedir. Yakıt kanalının (11) enjektör gövdesi iç yüzeyi (12) ile enjektör iğnesi arasındaki halka şeklindeki yakıt kanalına açılan kesiti (13) günümüzde yaygın olarak kullanılan basınç odalı (5) enjektör sistemlerinden farklı olarak çok daha geniş bir açıya sahip olduğundan keskin ve ince cidarlı bir geometrinin oluşması önlenmektedir. Böylece enjektör meme gövdesi iç yüzeyinde yakıt kanalının birleşim bölgesine (13) gerilim birikimine engel olmak için bir basınç odası ile ilavehacim oluşturma zorunluluğu ortadan kalkmaktadır.Bu durum enjektör iç yüzeyine (4,12) ek bir basınç odası (5) açma işlemi gerektirmediği için üretimmaliyetini düşürmektedir. Basınç odasının (5) ortadan kalkması ani kesit değişimlerinin ve ilave hacmin neden olacağı hidrolik kayıplar, DEVAMI VAR. The present invention envisages making the injector system commonly used in internal combustion engines as two separate parts, the upper body (7) part of the injector nozzle and the lower body (8) part where the injection holes are located. The section (13) of the fuel channel (11) opening to the annular fuel channel between the inner surface of the injector body (12) and the injector needle, has a much wider angle, unlike the injector systems with a pressure chamber (5), which are widely used today, so it is sharp and thin-walled. geometry is prevented. Thus, the necessity of creating an additional volume with a pressure chamber in order to prevent the accumulation of tension in the junction area of the fuel channel (13) on the inner surface of the injector nozzle body is eliminated. lowers. Hydraulic losses caused by the disappearance of the pressure chamber (5), sudden cross-section changes and additional volume, CONTINUED.
