Emission and operational metrics of algae biodiesel (FAME)-powered diesel engine enhanced with Fe2O3 nanomaterials and lanthanum zirconate-based coating system.

The depletion of fossil fuel attracts researchers to search for alternative fuels. Bio-fuels are gaining more attention nowadays due to their less pollution characteristics. Further, more energy can be extracted from it by adding nano-additives. In addition, thermal barrier coating of engine parts provides added advantages. In this current research, an attempt was made to study the influence of lanthanum zirconate thermal barrier coating and iron oxide on behavior of diesel engine driven by algae biodiesel (FAME). The engine was tested with different energy sources. The behavior of the engine was analyzed based on the experimental data by comparing the different fuels' performance. Results showed that the nanoparticles showed significant influence on engine operation. Further, coating provided notable changes in performance of the engine in positive manner. The B20C/Fe2O3 explored the least BSFC (0.32 kg/kW h) plus maximum BTE of 34% by the BP of 5 kW. Further, the emissions were notably controlled in relation to diesel fuel.
