Özet:

 In this research, the potential effects of titanium dioxide TiO2 nanoparticles on improving a stationary diesel engine characteristic fuelled with a biofuel mixture-diesel blend B25: 25 vol. biofuel mixture containing biodiesel, waste cooking oil and ethanol  75 vol. diesel are experimentally investigated. TiO2 nanoparticles are dispersed in B25 fuel at 50, 100, and 150 ppm concentrations. Subsequently, they are tested in a stationary research diesel engine at a rotational speed of 1500 rpm and specific loads. Nanoparticles enhance combustion, offering increased cylinder gas pressure, net heat release rate, and reduced ignition delay period and combustion duration. The engine performance is enhanced more with increasing nanoparticle concentration. TiO2 nanoparticles with a 150 ppm rate reduce brake-specific fuel consumption by 3.21 and increase the brake effective efficiency by 3.67, on average, compared to B25 fuel without nanoparticles. CO emission and smoke opacity are reduced by up to 31.89 and 24.56 with TiO2 nanoparticles. However, under the same operating conditions, NO emission increases to 30.58 compared to sole B25. Nevertheless, the NO emission of nanofuels is still less than that of diesel fuel. This studys results indicate that using TiO2 nanoparticles as a nano fuel additive can enhance the stationary engines operation fueled with the biofuel mixture-diesel blend.

 Bu araştırmada titanyum dioksit TiO2 nanopartiküllerinin, biyoyakıt-dizel karışımı B25: biyodizel, atık kızartma yağı ve etanol içeren 25 hacimli biyoyakıt karışımı  75 dizel ile çalışan stasyoner dizel motorunun performans ve emisyonlarını iyileştirme potansiyeli deneysel olarak incelenmiştir. TiO2 nanopartikülleri B25 yakıtına 50, 100 ve 150 ppm konsantrasyonlarında eklenmiştir. Elde edilen nanoyakıtlar, stasyoner bir dizel motorda 1500 ddk dönüş hızında ve farklı yüklerde test edilmiştir. Nanopartiküller yanmayı iyileştirerek, silindir basıncını ve net ısı yayılım oranını artırmış, tutuşma gecikmesi süresi ile yanma süresini kısaltmıştır. Nanopartikül konsantrasyonu arttıkça motor performansı daha da iyileşmiştir. 150 ppm oranındaki TiO2 nanopartikülleri, nanopartikül içermeyen B25 yakıtına kıyasla özgül yakıt tüketimini 3,21 oranında azaltmış ve efektif verimi ortalama 3,67 oranında artırmıştır. TiO2 nanopartikülleri kullanımı ile CO emisyonu ve duman koyuluğu 31,89 ve 24,56ya kadar azalmıştır. Bununla birlikte, aynı çalışma koşullarında NO emisyonu, nanopartikül içermeyen B25 yakıtına kıyasla 30,58e kadar artmıştır. Ancak nanoyakıtlar dizel yakıtına göre daha az NO emisyonu oluşturmuştur. Bu çalışmanın sonuçları, TiO2 nanopartiküllerinin nano yakıt katkısı olarak kullanılmasının biyoyakıt-dizel karışımıyla çalışan stasyoner dizel motorun performans ve emisyonlarını iyileştirebileceğini göstermektedir.
