To discuss this issue, this work presents a comparison between a 3rd generation biodiesel production plant and a methanol synthesis facility, powered by photovoltaic (PV) electricity from sunlight. The objective is to evaluate the energy efficiency of the two production processes (by means of ...
Analysis of the performance results revealed that most of the biodiesel generally give higher brake thermal efficiency and lower brake-specific fuel consumption. Emission results showed that in most cases, NOx emission is increased, and HC, CO, and PM emissions are decreases. It was reported that...

Comparison on engine performance and emission between the emulsified fuels, diesel and Jatropha methyl ester (JME) are discussed in this paper. The experimental results indicate that the biodiesel bio-oil emulsions enhance the combustion efficiency with improved engine performance and lower tailpipe ...

Environmentally, biodiesel is significant because most exhaust emissions, with the exception of nitrogen oxides (NOx), are reduced in comparison to conventional diesel fuel. Thus, the reduction of NOx exhaust emissions is a major research challenge to biodiesel. Other significant research areas are ...
Unburned hydrocarbon, carbon monoxide and smoke emissions improved with third-generation fuels (MB10, MB20) in comparison to base diesel fuel and second-generation fuels (JB10, JB20, PB10 and PB20). Oxides of nitrogen emissions were slightly increased with both the third- and second-generation...

In addition, there has not been a direct comparison of combustion and emission properties between these gaseous and emulsified pilot fuels. Here, a direct comparison was drawn between a gaseous pilot fuel (dimethyl ether or DME), two emulsified pilot fuels (5% and 10% water-in-RME emulsions)...
