Havacılık Yakıtı Jp-8 Ve Dizel Karışımlarının Tek Silindirli Bir Dizel Motorunda Performans Ve Egzoz Emisyonlarına Etkisi

Öz

Bir havacılık yakıtı olan JP-8, 1980li yılların sonlarına doğru NATO ülkeleri ortak askeri yakıtı olarak kabul edilmiştir. % 99,8’i kerosenden meydana gelen JP-8, askeri uygulamalara uygun hale getirebilmek için çeşitli katkı maddeleri ile karıştırılmaktadır. JP-8 yakıtının en önemli özelliği donma noktasının -40oC’nin altında olmasıdır. Bu çalışmanın amacı JP-8 yakıtının referans dizel yakıtı ile çeşitli oranlarda harmanlanarak kullanım imkanını araştırmaktır. Bu çalışmada JP-8 yakıtı tek silindirli, 4 zamanlı ve direkt enjeksiyonlu bir dizel motorunda referans dizel yakıtına hacimsel olarak %5, %10, %25 ve %50 oranlarında ilave edilmiş, motor performans parametreleri ve egzoz emisyonları incelenmiş ve referans dizel yakıtı sonuçları ile karşılaştırılmıştır. Motor momenti ve özgül yakıt tüketimi JP-8 karışımlı yakıtlarda referans dizel yakıtına göre kötüleşme göstermiştir. Egzoz emisyonları bakımından NOx emisyonları JP-8 karışımlı yakıtlarda referans dizel yakıtına göre iyileşirken, CO ve is emisyonlarında artış gözlenmiştir.
