Therefore, biodiesel has been made by transesterification from cotton seed oil and then it was mixed with diesel fuel by 25% volumetrically, called here as B75 fuel. B75 fuel was tested, as alternative fuel, in a single cylinder, four strokes, and air-cooled diesel engine. The effect of B75 and diesel fuels on the engine power, engine torque and break specific fuel consumption were clarified by the performance tests. The influences of B75 fuel on CO, HC, NOx, Smoke opacity, CO2, and O2 emissions were investigated by emission tests. The engine torque and power, for B75 fuel, were lower than that of diesel fuel in range of 2–3%. However, for the B75, specific fuel consumption was higher than that of diesel fuel by approximately 3%. CO2, CO, HC, smoke opacity and NOx emissions of B75 fuel were lower than that of diesel fuel. The experimental results showed that B75 fuel can be substituted for the diesel fuel without any modifications in diesel engines.Öğe Biyodizelin hava kirliliğine etkisi(Batman Üniversitesi, 2012-06-01) Aydın, Hüseyin; Aydın, Selman; İlkılıç, CumaliBu çalışmada aspir yağından transesterifikasyon (yağın yeniden esterleştirmesi) yöntemi ile biyodizel üretilmiştir. %20 aspir biyodizeli %80 dizel karışımlı yakıt ile normal dizel yakıtı (D2) tek silindirli, dört zamanlı, direkt püskürtmeli ve hava soğutmalı bir dizel motorunda kullanılarak egzoz emisyonları karşılaştırmalı olarak incelendi.

Many of these studies have ever been on the usability of vegetable oils in diesel engines. In the current work, biodiesel were produced from waste fish oil (FOB), hazelnut oil (HOB), rapeseed oil (ROB), and waste cooking oil (WCOB) by transesterification method. The same optimized variables of 6:1 methanol/oil molar ratio (mol/mol), 0.4% sodium methoxide concentration (wt.%), 60°C reaction temperature, 1000 rpm agitation speed and 2 h reaction time conditions were performed for biodiesel production from all kinds of above mentioned oils. Some of the important chemical and physical properties of test fuels were found. Without making blends with diesel fuel, pure biodiesels were used in a diesel engine in order to clarify how their usage effects on engine performance and exhaust emission parameters. When compared with those of diesel fuel, average torque and power were reduced while brake specific fuel consumption was increased for biodiesels. Besides, carbon monoxide (CO), hydrocarbon (HC) emissions were considerably lower for biodiesel usage while oxides of nitrogen (NOx) emissions were higher than that of diesel fuel. Furthermore, emissions of carbon dioxide (CO2) and smoke opacity were reduced for biodiesel usage. Oxygen (O2) contained in the exhaust gases were higher for biodiesels while they contain more oxygen molecules in their structureÖğe Exhaust emissions of a CI engine operated with biodiesel from rapeseed oil(Taylor & Francis, 2011-01-16) Aydın, Hüseyin; İlkılıç, CumaliIn this study, biodiesel was produced from rapeseed oil and was used in a single cylinder, naturally aspirated and direct-injected diesel engine as pure biodiesel (B100) and as a blend with standard diesel fuel by 20% biodiesel to 80% diesel fuel (B20). The diesel engine emissions and some performance parameters were investigated at fully loaded engine conditions. The effects of pure biodiesel and its blend with diesel fuel on emissions of carbon monoxide (CO), nitrogen oxides (NOx), carbon dioxide (CO2), and sulfur dioxide (SO2) were clarified. Results showed that biodiesel fuel is environmentally friendly since it reduced the emissions of CO, SO 2, and CO2 of engines at all speeds. Results also indicated that the pure biodiesel gave about 12% lower power and 20 to 25% higher fuel consumption as compared to diesel. However, the results were almost the same or slightly different from a blend of biodiesel-diesel and petroleum diesel fuel.Öğe Analysis of combustion, performance and emission characteristics of a diesel engine using low sulfur tire fuel(Elsevier, 2015-03-01) Aydın, Hüseyin; İlkılıç, CumaliAn alternative fuel for diesel engines was produced from waste vehicle tires by the method of pyrolysis. In order to reduce sulfur content of produced the liquid fuels, during the reaction Ca(OH) 2 was used. Then, H 2 SO 4 were used after the reaction and the sulfur content of the product was reduced by 83.75%. The properties of diesel fuel, low sulfur tire fuel and fuel mixtures of low sulfur tire fuel and diesel fuel were found. Then the prepared fuel blends and diesel fuel were tested in a diesel engine. Performance, combustion and emission parameters of the engine when using each fuel were obtained and comparisons were made with D2 fuel. Power, torque and mean effective pressure, mass fuel consumption, effective efficiency and bscf values presented. Results justify that the performance of the engine slightly lowers by using blends of LSTF. Cylinder pressure and heat release rate values of the test fuels usage were quite similar with those of D2. CO, HC, and smoke emissions were slightly higher while NOx emissions were lower for LSTF blends. All of these results indicate that desulfurized tire fuels with low percentages can be used as alternative fuel in diesel engine.Öğe Bir dizel motorunda kanola yağı kullanımında ön-ısıtma işleminin egzoz emisyonlarına etkilerinin deneysel araştırılması(e-Journal of New World Sciences Academy, 2009-03-01) Aydın, Hüseyin; Öner, Cengiz; İlkılıç, Cumali; Hazar, HanbeyBu çalışmanın amacı; bitkisel yağlardan olan kanola yağının önceden ısıtılarak bir dizel motorunda kullanımından kaynaklanan egzoz emisyonlarının nasıl değiştiğini incelemektir. Bu amaçla saf kanola yağı %20 ve %50 oranlarında dizel yakıtı ile karıştırılmış ve bu karışım yakıtlar dört zamanlı, tek silindirli ve hava soğutmalı bir dizel motorda kullanılmıştır. Karışım yakıtlar kullanım sırasında 100o C sıcaklığa kadar ısıtıldıktan sonra kullanılmış ve bu ön ısıtma işleminin dizel motorda ısıl verim, egzoz gazı sıcaklığı, NOx, CO ve duman emisyonlarına etkileri araştırılmıştır. Ön ısıtma işleminin CRO’ nun viskozitesini azalttığı ve daha uygun bir yakıt akışı sağlayarak emisyonlar üzerinde olumlu etki yaptığı sunucuna varılmıştırÖğe Terebinth oil for biodiesel production and its diesel engine application(Journals & Books, 2015-08) Aydın, Hüseyin; İlkılıç, Cumali; Çılğın, ErdalIn this study, biodiesel was produced from terebinth oil by the well known transesterification process in the methyl alcohol environment. Terebinth is non-edible oil, thus food versus fuel conflict will not arise if this is used for biodiesel production. The optimum conditions of transesterification process for biodiesel production are investigated in this study. A maximum of 77% biodiesel was produced with 20% methanol in presence of 1% sulphuric acid (H2SO4). The resulting biodiesel is quite similar to conventional diesel fuel in its main characteristics. The obtained biodiesel from terebinth oil was added to diesel fuel volumetrically by 10% and 50%. The fuel mixtures that obtained from the addition of 10% and 50% of biodiesel were named here as B10 fuel and B50 fuel. Performance and exhaust emissions of biodiesel in a compression ignition engine were experimentally investigated. Biodiesel blends have lowered power output with increased brake specific fuel consumption (Bsfc) probably due to the lower heating value of biodiesel. The engine experimental results showed that exhaust emissions including carbon monoxide (CO), carbon dioxide (CO2), and hydrocarbons (HC) were reduced for all biodiesel fuel mixtures. However, a slight increase in oxides of nitrogen (NOx) emission was experienced for biodiesel mixtures.Öğe Air pollution, pollutant emissions and harmfull effects(Batman Üniversitesi, 2017) Aydın, Hüseyin; İlkılıç, CumaliPresent paper is an overview of the engine and air pollution problem especially in the urban areas. Air pollution is caused bu pollutant emissions is popular problem that should be solved in the world by means of its harmfull effects. The combustion processes of diesel and gasoline fuels in realted engines and other hydrocarbon fuels in termical machines are main sources of air pollutant emissions. These main pollutants are nitrogen oxides (NOx), carbon dioxide (CO2), sulphur oxides (SOx), hydrocarbons (HC), carbon monoxide (CO), particulates matter (PM), lead (Pb), and volatile organic compounds (VOCs). All these emissions are firstly introduced and classified in the view of their sorces and formation processes. Then, their negative and harmfull effects on global warming, environment and human healt have been presented. Finaly the processes and technologies of reducing these pollutant emissions were presented.
