Transesterification of crude Jatropha oil by activated carbon-supported heteropolyacid catalyst in an ultrasound-assisted reactor system
Badday, Ali Sabri; Abdullah, Ahmad Zuhairi; Lee, Keat-Teong - In: Renewable Energy 62 (2014) C, pp. 10-17
Transesterification of crude Jatropha oil in presence of tungstophosphoric acid (TPA) supported on activated carbon (AC) using ultrasound-assisted process was investigated. The generated catalysts were characterized for physical and chemical properties to examine the effects of different TPA...

Combustion, performance and emission characteristics of direct injection diesel engine fueled by Jatropha hydrogen peroxide emulsion
Nguyen, Kim-Bao; Dan, Tomohisa; Asano, Ichiro - In: Energy 74 (2014) C, pp. 301-308
Recently, Jatropha, a fast growing tropical plant, has caught the attention of researchers because the oil produced from Jatropha is a non-edible. However, worse emissions, when using raw Jatropha oil in diesel engines, have been reported in the literature due to its higher viscosity and lower...

Effect of double injection on combustion, performance and emissions of Jatropha water emulsion fueled direct-injection diesel engine
Nguyen, Kim-Bao; Dan, Tomohisa; Asano, Ichiro - In: Energy 80 (2015) C, pp. 746-755
of second injections. The acquired data was analyzed for various combustion parameters such as heat release rate …, combustion center (timing of 50% of total heat release), ignition delay, and combustion duration; for performance parameters such … average in-cylinder temperatures. We also found a drastic increase in the ignition delay, combustion duration, and a shift in …
