Experimental analysis of VCR diesel engine exhaust emissions with zirconium dioxide and basalt based catalytic converter using lemon grass oil

The automobile has a significant impact on pollution levels. The primary causes of air pollution are motor vehicle exhaust and fossil fuel burning. Controlling harmful emissions such as CO, NOx, and HC is an essential task for future generations. The goal of the project is to reduce automotive emissions by designing and fabricating a basalt catalytic converter to replace conventional metals such as platinum, cerium, and rhodium. To lower an engine's emissions, various materials are utilised. The many mechanical properties of one material named Basalt are known. This is used to test and evaluate basalt-fiber composite materials to decrease NOx by 8–9.7% and Mean increases in emissions of CO and HC respectively of 7.3–9.78% and 8.6–10.5% have been observed..The composite material for basaltic fiber has been prepared with epoxy resin and cut into circular forms of the required diameter with troughs. The basalt pieces inside the catalytic converter were tested.. Lemongrass oil and diesel in specified amounts were used in the experiment. The NOx levels were significantly reduced as a result of the experiment.
