“…The BD has more oxygen molecules in its chemical composition, about 11% when compared to petroleum diesel. This excess oxygen molecule creates rich local oxygen concentration that promotes the rate of the combustion process in CI engines [23][24][25]. Devarajan et al [26] and Rajak et al [27] stated that the reasons for more NOx production from the DE powered with diverse fuels like neem and microalgae BD are due to more oxygen molecules in their chemical composition that advanced combustion.…”

Biodiesel (BD) is one of the efficient alternative fuels for diesel engines (DE) which can be employed sans any modifications. The present study is focused on the extraction of BD from a lemongrass plant and analyzing combustion, efficiency, and emission characteristics of the DE by adding NPs at different concentrations to reduce both hydrocarbon, carbon monoxide, and NOx emissions simultaneously from the DE. The fuel samples were prepared by adding different dosages of zinc oxide nanoparticles (ZnO NPs) with neat lemongrass biodiesel (LGB) such as 50 ppm, 100 ppm, 150 ppm, 200 ppm, and 250 ppm per liter. From the results, it is found that the properties of BD were improved by the addition of ZnO NPs and it increased oxygen concentration in the sample resulting in better combustion and lower exhaust pollutants. The DE tested with the LGB + 150 ppm sample has registered maximum brake thermal efficiency (BTE) and lower specific fuel combustion (SFC) for all loading conditions compared to other samples. The value of heat release rate (HRR) and in-cylinder pressure are higher for LGB + 150 ppm due to its specific properties compared to other LGB blends. The presence of ZnO NPs in LGB has reduced harmful emissions from the DE such as carbon monoxide (CO), hydrocarbon (HC), oxides of nitrogen (NOx), and smoke by 4.01%, 5.56%, and 19.01%, when compared to neat LGB.

“…Biyodizelin en önemli avantajları; yenilenebilir olması, moleküler yapısında kütlece yaklaşık %10-12 oranlarında oksijen bulunması, dizel yakıtıyla her oranda karışabilmesi ve parlama noktasının yüksek olmasıdır. Üretim maliyetinin (günümüz şartlarında) yüksek olması, ısıl değerinin (35-40 MJ/kg) düşük olması ve viskozitesinin yüksek olması biyodizelin en önemli yetersizlikleridir [6].…”

Dizel yakıtı+bitkisel yağ+dietilen glikol dimetil eter karışımlarının tek silindirli bir dizel motorda tam gaz ve farklı devirlerde (1000-2200 devir/dakika) kullanılmasının performans, yanma ve emisyon karakteristiklerine etkileri incelenmiştir. Maksimum silindir sıcaklığı değerleri ile maksimum silindir sıcaklığının elde edildiği krank mili açısı değerleri interpolasyon ve ekstrapolasyon yöntemleriyle tahmin edilmiştir. Silindir sıcaklığının devir sayısı ve krank mili açısına göre değişimi için en küçük kareler regresyonu yardımıyla 3-boyutlu bir denklem elde edilmiştir. Dizel yakıtı kullanımına göre, karışım yakıtları kullanıldığında ortalama olarak tutuşma gecikmesi, maksimum silindir sıcaklığı, egzoz gazı sıcaklığı ve emisyonlar (karbonmonoksit, is ve hidrokarbon) azalmış, fakat özgül yakıt tüketimi artmıştır. Hacimsel olarak % 4 oranında dietilen glikol dimetil eter içeren karışım için efektif verim (% 1.4895), efektif güç (%2.5552), maksimum silindir basıncı (% 2.0448) ve maksimum ısı yayılımı oranı (% 7.6845) artmıştır. Elde edilen 3-boyutlu denklem yardımıyla farklı yakıtlar için hesaplanan silindir sıcaklığı değerlerinin hata oranları % 5’in altındadır.

“…The results show that the high fuel consumption can be compensated by reducing the pumping loss under the corresponding load conditions. Allami et al [37] compared the changes in engine combustion (engine performance) and exhaust emission by using the injection system of a 6-cylinder diesel engine running at a constant speed of 1500 rpm with biodiesel of B10, B25, and B40 in different concentrations ratios. Hasan et al [38] studied in detail the various aspects of compression ignition engines fueled with methanol/diesel fuel.…”

This paper introduces the theoretical basis and optimization method of diesel engine working process theory. By comparing two Miller cycle schemes of B20 biodiesel under different load conditions of 1000 rpm (100%, 75%, and 50%), the best Miller cycle scheme and the best Miller degree were found. Then, based on the Miller cycle scheme, its performance was optimized and analyzed, and the best intake timing scheme of the B20 biodiesel engine under different working conditions was obtained. The results show that the performance of B20 biodiesel in variable valve overlap angle Miller cycle is better than that in variable cam profile Miller cycle, and the effect is the best when the Miller degree is 30 °CA. When B20 biodiesel is used under 100% and 50% load conditions, the maximum power under the two loads is in the area near intake valve timing 179 °CAA and exhaust valve timing 174 °CAA, and intake valve timing 224.5 °CAA and exhaust valve timing 119 °CAA, respectively. Fuel consumption, soot emissions, and NOx emissions also have the corresponding best performance intake valve and exhaust valve positions.
