Abstract

İklim değişikliği, fosil yakıtların azaltılmasını ve yenilenebilir enerji kaynaklarının artırılmasını zorunlu kılmaktadır. Diğer taraftan, COVID-19 süreci dezenfektan ihtiyacını artırmış olup, alkolün yakıt olarak kullanımı yasaklanmıştır. Dezenfektan olarak kullanılamayan fuzel yağı, şeker fabrikalarında pancar melasından etil alkol üretimi sonrası geriye kalan çok kötü kokulu atık alkol karışımıdır. Bu çalışmada benzin içerisine farklı volumetrik oranlarda fuzel yağı ve sentetik mangan katkısı ilave edilerek motor performansı, özgül yakıt tüketimi ve emisyonlar üzerindeki etkileri incelenmiştir. Volumetrik yakıt karışımları olarak %5, %10, %15 ve %20 oranları belirlenmiştir. Karışımların viskozite, donma noktaları, parlama noktaları baz alınarak yapılan testlerde laboratuvar şartlarında benzin içerisine %15 fuzel yağı eklenmesi en uygun ideal karışım (F15B85) olarak belirlenmiştir. F15B85 test yakıtı içerisine sırasıyla 4-8-12 ve 16 ppm organik reçine esaslı mangan katkı maddesi ilave edilerek 4ppmF15B85, 8ppmF15B85, 12ppmF15B85, 16ppmF15B85 deneysel yakıtları oluşturulmuştur. Elde edilen deneysel yakıtlar atmosferik şarjlı benzinli bir motorda ölçüm testleri yapılarak motor performansı ve emisyon değerleri incelenmiştir. Deneysel sonuçlara göre 12ppmF15B85 yakıtı motor performans ve emisyonlar açısından diğer yakıt karışımlarına göre olumlu sonuçlar vermiştir. Motor performanslarında ortalama olarak torkta %4,18, güçte %5,04, BSFC (Fren özgül yakıt tüketimi)’de %3,12 artış, EGT (Egzoz gaz sıcaklığı)’de %2,48 azalma tespit edilmiştir. Egzoz emisyonları açısından bakıldığında CO (Karbonmonoksit) ve HC (Hidrokarbon)’de sırasıyla ortalama olarak %20,69, %10,51 azalma, CO2 (Karbondioksit) ve NOx (Azotoksit) de ise %3,65, %5,10 artış tespit edilmiştir.

Investigation of the Effects of Synthetic Manganese Additive and Fusel Oil-Gasoline Mixtures on Performance and Emissions in a Spark Ignition Engine

Abstract

Climate change necessitates reducing fossil fuels and increasing renewable energy sources. On the other hand, the COVID-19 process has increased the need for disinfectants and the use of alcohol as fuel is prohibited. Fusel oil, which cannot be used as a disinfectant, is a very smelly waste alcohol mixture left after the production of ethyl alcohol from beet molasses in sugar factories. In this study, fusel oil and synthetic manganese additives in different volumetric ratios were added to gasoline and their effects on engine performance, specific fuel consumption and emissions were investigated.5%, 10%, 15% and 20% were determined as volumetric fuel mixtures.In tests based on the viscosity, freezing points and flash points of the mixtures, adding 15% fusel oil to gasoline under laboratory conditions was determined as the most suitable ideal mixture (F15B85). 4ppmF15B85, 8ppmF15B85, 12ppmF15B85, 16ppmF15B85 measurement fuels were formed by adding 4-8-12 and 16 ppm organic resin-based manganese additives into F15B85 test fuel, respectively. The engine performance and emission values were examined by making measurement tests in an atmospheric charged gasoline engine with the measurement fuels obtained. According to the experimental results, 12ppmF15B85 fuel gave positive results in terms of engine performance and emissions compared to other fuel mixtures. An average of 4.18% increase in torque, 5.04% increase in power, 3.12% increase in BSFC (Brake Specific Fuel Consumption) and 2.48% decrease in EGT (Exhaust Gas Temperature) were determined in engine performances. In terms of exhaust emissions, an average of 20.69%, 10.51% reductions in CO (carbon monoxide) and HC (hydrocarbon), respectively, and an increase of 3.65% and 5.10% in CO2 (Carbon dioxide) and NOx (nitrous oxide) were detected.
