Experimental investigation of performance and emission characteristics of diesel engine using pine oil blends

The experimental research is focused on use of biodiesel in compression ignition (CI) engines. The current depletion rate of fossil fuels raised the necessity to use renewable energy resources. The biodiesel is one of the best alternative energy resources which can compensate the shortage of diesel fuel. Biodiesel have properties and combustion parameters like to those of petroleum fuels and can be mixed together with petro-diesel. Biodiesel is synthesized from Pine seed oil using transesterification process and blended at different concentrations of B0, B10, B20, B30 and B100. The performance and emission analysis were carried on 4 stroke single-cylinder engine at various loads. The results proved that, along with the various blends used, B20 shows a decrease in pollutants of CO, CO2 and HC while the mechanical efficiency and brake thermal efficiency (BTE) of pine oil have increased by 4.85% and 23.2% respectively. B20 has shown an increase in NOx emission about 9.12%. So, B20 has a greater advantage for the direct use in engines.
