RO blended diesel fuel (DF) and emulsified multicomponent biofuels have been investigated. Fuel physicochemical properties have been analyzed. Experimental tests of a diesel engine D-245 in the operating conditions of the external characteristic curve and the 13-mode test cycle have been conducted to investigate the effect of these fuels on engine performances. CFD simulations of the nozzle inner flow were performed for DF and ethanol-emulsified RO. The possibility of a significant improvement in brake thermal efficiency of the engine has been noted. The efficiency of using blended biofuels from RO as a motor fuel for diesel engines has been evaluated based on the experimental test results. It was shown that in comparison with the presence of RO in emulsified multicomponent biofuel, the presence of water has a more significant effect on NOx emission reduction. The cont...

The concept of controlled anaerobic digestion is perhaps a much overlooked example of a way to reduce greenhouse gas emissions and to provide a better waste disposal method for organic waste. Today environmental pollution is a significant hazard and it occurs due to improper waste disposal techniques. People are not aware of the control techniques of waste disposal methods. Biogas digester is one of the best solutions for the control of waste, and more importantly, it can be used as a reliable renewable energy source. The research is focused on the development, popularization and sharing the best practices of biogas technology in Sri Lanka. This analysis basically discusses the raw material usage, applications of biogas, working status, type of funding for construction, locations of installation, composition, waste disposal methods, uses of biofertilizer, attitude of users of plant on the technology, willingness of user to obtain training on biogas technology, problems and failures encountered during operation, overall satisfaction of biogas consumers in Sri Lanka. This project is definitely not supposed to be revolutionary or radically new, but rather to be a starting point for further research and development in this area.
