Abstract

In this experimental study,
the influences of propanol and diesel mixtures on direct injection single
cylinder diesel engine fuel consumption and exhaust emissions were
investigated. Volumetrically, 3% propanol - 97% diesel and 6% propanol - 94%
diesel blends were used as test fuels. 
Fuel properties of the test fuels were analyzed and found different from
those of diesel fuel. In comparison with diesel, viscosity, heating value, flash point, density and
Cetane number decreased slightly. The engine tests were carried out at full
load condition of the test engine. Specific fuel consumption values of the
blend fuels showed decreasing trend. In general, exhaust emission values of the
blends improved. CO and
particulate emission values decreased up to 25.37% and up to 12.08%,
respectively. NO_x emission values with the blend fuels did not
change, considerably.

PROPANIN DİZEL YAKITIYLA KULLANIMI: DİZEL MOTOR YAKIT TÜKETİMİ İLE EGZOZ EMİSYONLARI ÜZERİNDEKİ ETKİLERİ

Abstract

Bu deneysel çalışmada propan-dizel yakıt
karışımlarının direk enjeksiyonlu tek silindirli dizel motorda kullanımının
yakıt tüketimi ve egzoz emisyonları üzerindeki etkisi araştırılmıştır. Hacimsel
olarak %3 propan-%97 dizel ve %6 propan-%94 dizel içeren karışımlar test yakıtı
olarak kullanılmıştır. Test yakıtlarına ait yakıt özellikleri dizel yakıt
özelliklerine göre farklılık göstermiştir. Dizel yakıtıyla kıyaslandığında,
viskozite, ısıl değer, parlama noktası ve setan değerlerinde düşük oranda
azalma olmuştur. Motor testleri tam yük şartlarında gerçekleştirilmiştir.
Karışımların özgül yakıt tüketimi değerlerinde düşme eğilimi gözlemlenmiştir.
Genel olarak, karışım yakıtlara ait egzoz emisyonu değerlerinde iyileşmeler
sağlanmıştır. CO ve Partikül madde emisyon değerlerinde sırasıyla % 25.37 ve
%12.08’lere ulaşan azalmalar elde edilmiştir. NO_x emisyonu
değerlerinde kayda değer bir değişim gözlemlenmemiştir.
