Abstract: This study examines the effect of changing the injection pressure on engine performance and emissions at full load using a singlecylinder, direct-injection (orijinal injection pressure is 200 bar) diesel engine with waste biodiesel. BD0 (pure diesel fuel), BD50 (50% diesel-50% biodiesel) and BD100 (100% biodiesel) were used as test fuel. When the experimental data are analyzed, it is determined that the optimal spray pressure for engine performance and emission parameters for BD0 fuel is 200 bar, while for BD50 and BD100 fuels it is 220 bar. It was found that the specific fuel consumption (SFC) decreased by 7% compared to the diesel fuel while the BD100 fuel was used and the injection pressure was 220 bar. In addition, compared to pure diesel, the emissions of nitrogen oxide (NOx) increased by 18%, while the emissions of hydrocarbons (HC), carbon monoxide (CO) and smoke were reduced by 29%, 21% and 22%, respectively. Exhaust gas temperature (EGS) and effective efficiency increased by 7% and 8% respectively at 220 bar. Özet: Bu çalışmada atık biyodizel kullanılan tek silindirli, direk püskürtmeli (orijinal püskürtme basıncı 200 bar) bir dizel motorda, tam yükte püskürtme basıncının değiştirilmesinin motor performans ve emisyonlara etkisi incelenmiştir. Deney yakıtı olarak BD0 (saf dizel yakıtı), BD50 (%50 dizel-%50 biyodizel) ve BD100 (%100 biyodizel) kullanılmıştır. Deneysel veriler incelendiğinde BD0 yakıtı için motor performans ve emisyon parametreleri açısından en uygun püskürtme basıncı 200 bar olur iken, BD50 ve BD100 yakıtları için 220 bar olarak belirlenmiştir. BD100 yakıtının kullanımı ile püskürtme basıncı 220 bar iken, özgül yakıt tüketiminin (ÖYT) dizel yakıtına kıyasla %7 civarında arttığı tespit edilmiştir. Ayrıca saf dizel yakıta kıyasla azotoksit emisyonu (NOx) %15 artarken, hidrokarbon (HC), karbonmonoksit (CO), ve is emisyonları sırasıyla %29, %21 ve %22 oranlarında azalmıştır. Egzoz gaz sıcaklığı (EGS) ve efektif verim ise 220 bar değerinde sırasıyla %7 ve %11 artmıştır.

Abstract: In this study, effect of using biodiesel on a single cylinder, four stroke, direct injection diesel engine as an alternative fuel, which was generated from waste oil on engine emissions and performance was investigated experimentally. In experiments, engine was tested with B0 (pure diesel fuel), B50 (50% diesel + 50% biodiesel) and B100 (100% biodiesel) test fuels at constant engine speed (2800 l / min) and different engine loads. Experimental data shows that hydrocarbon (HC), carbon monoxide (CO) and smoke emissions are reduced without significant loss in engine performance with the use of biodiesel. With the use of biodiesel, HC, CO and smoke emissions were decreased about 23%, 13% and 20%, respectively while NOx emissions increase about 13% compared to diesel fuel. However, specific fuel consumption (SFC) increased by 11%. Özet: Bu çalışmada tek silindirli, dört zamanlı, direkt püskürtmeli düşük güçlü bir dizel motorda atık yağlardan elde edilen biyodizelin kullanımının motor performans ve emisyonlarına etkileri deneysel olarak incelenmiştir. Testlerde motor; B0 (saf dizel yakıtı), B50 (%50 dizel + %50 biyodizel) ve B100 (%100 biyodizel) deney yakıtları ile sabit bir motor hızında (2800 1/min) ve farklı motor yüklerinde test edilmiştir. Deneysel verilere bakıldığında, biyodizel kullanımı ile motor performansında önemli ölçüde kayıp olmadan hidrokarbon (HC), karbonmonoksit (CO) ve is emisyonlarının azaldığı gözlemlenmiştir. B100 yakıtının kullanımı ile dizel yakıta kıyasla azotoksit (NOx) emisyonunda %13 oranında artış tespit edilirken, HC, CO ve is emisyonlarında sırasıyla %23, %13 ve %20 oranlarında azalma tespit edilmiştir. Bununla birlikte özgül yakıt tüketimi (ÖYT) %11 oranında artış göstermiştir.

Due to the rapidly growing human population in the world, the use of many underground diesel engines such as transportation, energy production, heavy industrial machinery also showed a rapid increase. Due to the widespread use of diesel engines, increasing performance and reducing harmful emissions while lowering fuel consumption are at the forefront of research into these engines. Due to the increase in environmental awareness around the world, both fossil fuels and fuel systems are being investigated for diesel engines. The main fuel used in diesel engines is diesel fuel. Diesel fuel from the secondary energy source class is also called motor. In diesel engines, many liquid or gaseous fuels are used as alternative fuels. They are alternative gas fuels used in hydrogen, natural gas, LPG, DME and biogas diesel engines. The fuels that are currently the easiest to find and access in this class of fuel are LPG and natural gas. In this study, the effect of diesel / LPG dual fuel on engine performance and emissions was investigated experimentally. The tests were carried out at constant engine speed and five different engine loads. Experimental results show that there has been some increase in NOx emissions from reductions in CO and HC emissions to diesel fuel. It was observed that there has been improvement in specific fuel consumption, specific energy cost and effective efficiency.This document presents the formatting instructions for the Proceedings of the International Conference of Advanced Materials and Manufacturing Technologies (ICESE).
