Global energy crisis and environmental issues also have encouraged the quest for renewable and sustainable solutions to the traditional fossil fuels. Alternative biofuels based on water plants offer great potential as they are fast growing, do not compete with food crops and produce high biomass. In the present work, an aquatic weed Hydrilla verticillata was examined as a likely feedstock for biodiesel production. Solvent extracted oil by using n-hexane solvent helps in increasing the yield efficiency and fuel quality from Hydrilla plant feedstocks. The thus obtained oil was mixed with diesel in different ratios and experiments were carried out in a compression ignition engine. Prior to the use of this process analysis work done on zirconia material coated (0.5 mm) that is piston for checking the heat transfer of the piston from top to down with help of ANSYS software and also compared without coated engine. Further to enhance combustion and robustness across the blend range, A zirconia-based thermal barrier coated material was applied to the piston crown to increase in-cylinder heat and pressure to retention and minimize heat losses to the bottom of the piston. The zirconia coating promoted the higher Hydrilla–diesel fulcrum blend ratio and enhanced virility as could be observed in the experiments. The engine with coated piston showed better BTE, less specific fuel consumption and lesser dependency on conventional diesel. Analysis of exhaust emissions further showed that CO reduced, CO 2 increased, and unburned HC had decreased but NOx was also increased but kept within permissible limits. The results demonstrate the two-fold advantage of employing Hydrilla biofuel and thermal barrier coating as a collective technique for minimizing fossil fuel dependence and engaging with sustainable engine technologies.
