Bu
çalışmada, direkt enjeksiyonlu dizel bir motorda belirli oranlarda kullanılan
kanola yağı metil ester /motorin karışımlı yakıtların motor performans, emisyon
ve yanma parametreleri deneysel olarak araştırılmıştır. Ayrıca, çalışmada
kullanılan yakıtların motor üzerindeki etkisi sayısal olarak
incelenmiştir.  Sayısal çalışma AVL-FIRE
yazılımının ESE-Diesel kısmında gerçekleştirilmiştir. Deneysel çalışmada
kullanılan motor ve farklı yakıtlar sayısal olarak modellenmiştir. Motor
karakteristik özelliklerinin incelendiği deneysel çalışmada, biodizel karışımlı
yakıtlar motor performansını çok az da olsa düşürmüştür. Ancak bu yakıtlar
motorda CO ve HC gibi emisyonların azalmasına neden olmuştur. Hem deneysel hem
de sayısal yanma analizlerine bakıldığında, biodizel/motorin karışımlı
yakıtların silindir içi maksimum basınçların ve ısı salınımlarının artmasına
neden olduğu görülmektedir. Ek olarak bu çalışmada, AVL-FIRE
yazılımında yanma odası içerisindeki CO oluşumu farklı krank açılarında
incelenmiştir.
