Öz

Mevcut enerji senaryolarında artan enerji ihtiyacı ve hızla tükenen ve yenilenebilir olamayan petrol ürünleri gibi enerji kaynakları yenilenebilir ve alternatif yakıt araştırmalarına ivme kazandırmıştır. Petrol ve dizel yakıtlarının aşırı kullanılması nedeniyle artan kirlilik ele alınması gereken başka bir önemli konudur. Düşük emisyon özellikleri ve enerji yoğunluk dengeleri ile biyodizel, her geçen gün petrol türevi yakıtların yerini almaktadır. Bu çalışmada Yerel olarak ve bol miktarda bulunan Honge Yağı Metil Esteri (HOME) olarak adlandırılan ve honge yağından elde edilen biyodizel alternatif yakıt olarak kullanılmıştır. Daha sonra hibrit yakıt karışımları hazırlamak için farklı metal ve metal-oksit nano partikülleri HOME ‘a eklendi. Biyodizel-nanopartikül karışımları, bir ultra sonikatör yardımıyla hazırlandı ve kullanılan nanopartiküller 25ppm ve 50 ppm arasında kütle fraksiyonunda değiştirildi. Deneysel araştırmalar tek silindirli 4 zamanlı bir dizel motorda, yakıt olarak biyodizel-nanopartikül karışımlarının performans, yanma ve emisyon değerlerine etkisi için gerçekleştirildi. Sonuç olarak HOME ‘a nano parçacıkların ilavesi ile motorda zararlı egzoz emisyonu azalma ve fren termal verimliliğinde önemli artış meydana gelmiştir.

Experimental investigation on direct inj. diesel engine fuelled with graphene,silver and multiwalled carbon nanotubes-biodiesel blended fuels

Öz

In the present energy scenario of increased energy demand and rapid depletion of high energy non-renewable energy resources like petroleum products the search for new renewable and alternative fuels has gained momentum. Increased pollution due to the excess use of such petroleum and diesel fuels for varied energy requirements is another important issue to be addressed. Due to their low emission characteristics and equivalent energy density biodiesel are becoming more useful in replacement for petroleum fuels. In the present work biodiesel derived from honge oil called Honge oil methyl ester (HOME) was used as an alternative fuel as it was locally and abundantly available. Different metal and metal oxide nano-particles were then added to HOME to prepare novel hybrid fuel blends. Biodiesel-nanoparticles blends were prepared with the aid of an ultra-sonicator and the nanoparticles used were varied in the mass fraction of 25ppm and 50ppm. Experimental investigations were carried out on a single cylinder four stroke diesel engine fuelled with biodiesel-nanoparticle blends to determine performance, combustion and emission characteristics. The result showed considerable enhancement in the brake thermal efficiency with reduced harmful exhaust emission from engine with addition of nano-particles to HOME.
