Effect of microalgae, tyre pyrolysis oil and Jatropha biodiesel enriched with diesel fuel on performance and emission characteristics of CI engine

The objective of present paper, the exhaust emission parameters blend of Jatropha, tyre pyrolysis oil and spirulina microalgae biodiesel diesel engine with a rated power of 3.5 kW at 1500 rpm. The engine was operated at constant compression ratio of 17.5 with different engine loads were applied. Comparative parameters measures of brake thermal efficiency (BTE), fuel consumption, exhaust temperature, sauter mean diameter, smoke emission, particulate matter (PM), oxides of nitrogen (NOX) and carbon dioxide (CO2) have been presented. The secondary blends (JMETPO20, SP20) meaningfully reduction in smoke, PM and NOX emissions from the diesel engine, while the improved CO2 emissions. The result shows reduction in smoke, PM and NOX emission was observed with 20% blends. Reduction in smoke emission by 11.58%, 18.33%, PM emission by 5.3%, 33.1% and NOX emission by 10.2%, 10.66% but CO2 emission slightly higher for JMETPO20 (80% JME + 20% TPO) and SP20 (80% diesel + 20% spirulina) respectively at full load condition. Numerical and experimental results are valid for diesel engines of conventional diesel fuel, using 220 bar fuel injection pressure. Validation work is performed through the proposed numerical solver using experimental results.
