Abstract

İçten yanmalı motorlarda yanma odasındaki ani basınç artışından dolayı ortaya çıkan gürültüyü indirgemek amacıyla ön püskürtme yapılmaktadır. Ancak geleneksel sistemlerde enjektör memesi deliklerinin kesit alanı ön püskürtme aşamasında da sabit kalmakta olup ön püskürtme esnasında daha düşük bir debinin o sabit kesit alanından gönderilmesi sebebiyle kötü bir yakıt hava karışımı oluşturulmakta ve de neticesinde emisyon değerleri kötüleşmektedir. Bu sebeple enjektör eksenine göre memede bulunan üstüste iki sıra deliğin açılma ve kapanmasını ayrı ayrı kontrol eden bir dış iğne ve iç iğneden oluşan bir sistem kullanılmaktadır.Burada açıklanan buluş enjektör eksenine göre memede bulunan üstüste iki sıra deliğin (2, 3) açılma ve kapanmasını kontrol eden dış iğne (4) ile iç iğneden(5) oluşan sistemde, iğnelerin oturma yüzeylerinin genişliği nedeniyle enjektör memesi delikleri (2, 3) kapalı konumda iken, meme deliklerinde sızdırmazlığın sağlanması için, içi oyuk olan dış iğnenin DEVAMI VAR.
