An Investigation of Blends of Gasoline and Pyrolytic Oil Derived from Waste Vehicle Tires with Diesel Fuel in Diesel Engines

Öz

Researchers have focused on the search for alternative fuels for internal combustion engines for many years. The effects of pyrolytic oil derived from waste vehicle tires on the combustion and exhaust parameters of diesel engines were investigated in this study. ATL was produced by pyrolysis and is commercially available. For this purpose, an experimental study was carried out on a 4-stroke, 4-cylinder, 1.9 L multi-jet diesel engine. Pure diesel and B20 (80% diesel + 20% gasoline) and P20 (80% diesel + 20% pyrolytic oil)) were used as fuel. In this study, gasoline and pyrolytic oil were compared to investigate an alternative fuel to gasoline in the dual fuel method applied in diesel engines. In this study, engine load was kept constant at 25% of maximum engine torque and examined at various engine speeds. The data obtained have shown that the fuels utilized can be used without the engine fuel system needing to be modified. Thermal efficiency and specific fuel consumption both increased, when P20 fuel was used. Moreover, B20 and P20 have been used to decrease HC emissions, and the results are promising. It has been found that the pyrolytic oil made from the used tires of the vehicles used in the current investigation can be used as an alternative fuel in diesel engines.

Dizel Motorlarda Benzin ve Atık Araç Lastiklerinden Elde Edilen Pirolitik Yağın Dizel Yakıt ile Karışımlarının Araştırılması

İçten yanmalı motorlarda alternatif yakıt arayışları uzun yıllardır araştırmaların yoğunlaştığı konulardan birisini oluşturmaktadır. Bu çalışma kapsamında, dizel bir motorda atık taşıt lastiklerinden (ATL) elde edilmiş pirolitik yağın (PY) yanma karakteristikleri ve egzoz emisyonlarına etkileri üzerine bir araştırma yürütülmüştür. ATL piroliz yöntemiyle üretilmiş ve hazır olarak temin edilmiştir. Bu amaçla, 4 zamanlı 4 silindirli 1.9 litre hacmine sahip, multijet bir dizel motor üzerinde deneysel bir araştırma gerçekleştirilmiştir. Çalışmada, dizel yakıtı ve %20 karışım oranlarında benzin B20(%80 dizel + %20 benzin) ve pirolitik yağ P20(%80 dizel + %20 pirolitik yağı) yakıt olarak kullanılmıştır. Bu çalışmada benzin ve pirolitik yağ kıyaslanarak dizel motorlarda uygulanan çift yakıt metodunda, benzine alternatif bir alternatif yakıt araştırması yürütülmüştür. Çalışmada, maksimum motor momentinin %25 kadar bir motor yükü sabit tutularak değişen motor devirlerinde araştırma yürütülmüştür. Elde edilen verilere göre kullanılan yakıtların motor yakıt sisteminde bir revizyon gerektirmeden kullanılabileceği gösterilirken, gelişmiş yanma stratejileri için bir bakış açısı ortaya konulmuştur. Özelikle P20 yakıtı kullanımında özgül yakıt tüketimi ve termal verimde iyileşme gözlenmiştir. Ayrıca B20 ve P20 kullanımları ile HC emisyonlarının kontrolüne dair umut verici sonuçlar elde edilmiştir. Sonuç olarak, mevcut çalışmada kullanılan ATL’den üretilmiş PY’nin dizel motorda alternatif yakıt olarak kullanılabileceği gözlemlenmiştir.
