Bu çalışmada, Birincil Referans Yakıtı (BRY) (% 85 izo-oktan ve % 15 n-heptan) ile çalıştırılmış homojen dolgulu sıkıştırma ile ateşlemeli (HCCI) bir motorun simülasyonu için kullanılan sıfır boyutlu (0-B) ve üç boyutlu (3-B) yazılımların performansı incelenmiştir. 0-B yazılım olarak Stokhastik Reactor Model (SRM) tekniği ile motor yanması analizleri yapabilen SRM Suit kullanılmıştır. 3-B motor yanması simülasyonları için Hesaplamalı Akışkanlar Dinamiği (HAD) simülasyonları yapabilen Ansys-Fluent programı kullanılmıştır. Her iki ticari yazılım ile HCCI motor için yapılan simülasyonlar silindir içi basınç değişimi, ısı yayılım oranı ve emisyonlar açısından incelenmiştir. BRY yakıtının yanma analizinin yapılabilmesi için Tsurushima tarafından geliştirilen 33 bileşen ve 38 reaksiyon içeren kimyasal kinetik mekanizma kullanılmıştır. Analiz sonuçları ile deneysel basınç, ısıl yayılım oranı ve emisyon değerleri kıyaslanmıştır. Analiz sonuçlarına bakıldığında her iki yazılımın birbirlerine göre avantajları ve dezavantajları olduğu görülmüştür. 

In this study, performance of zero and three dimensional simulations codes that used for simulate a homogenous charge compression ignition (HCCI) engine fueled with Primary Reference Fuel PRF (85% iso-octane and 15% n-heptane) were investigated. 0-D code, called as SRM Suite (Stochastic Reactor Model) which can simulate engine combustion by using stochastic reactor model technique were used. Ansys-Fluent which can simulate computational fluid dynamics (CFD) was used for 3-D engine combustion simulations. Simulations were evaluated for both commercial codes in terms of combustion, heat transfer and emissions in a HCCI engine. Chemical kinetic mechanisms which developed by Tsurushima including 33 species and 38 reactions for surrogate PRF fuel were used for combustion simulations. Analysis showed that both codes have advantages over each other.
