Abstract
ABSTRACT Transportation sector and industrialisation both are having a major impact on the economic development and ecological nuisance of any country across the globe. NOx is a highly toxic gas, released from the combustion of diesel fuel. In this current experimental work, controls of NOx emissions are examined by using Exhaust Gas Recirculation (EGR). The investigational unit is operated with corn seed oil biodiesel blend. Performance, combustion and emission features are investigated at different EGR ratios (5%, 10% and 15%, respectively), and results are compared with diesel fuel. From the analysis of the experimental results, it is concluded that NOx emissions are decreased by increasing the EGR ratio. However, a small penalty of engine performance and increased soot formation are observed at a higher EGR ratio. From the experimental test results, it is confirmed that EGR technique implementation generated excellent results for the control of harmful NOx emissions.
