In perennial sectors like transportation, agriculture, industry, and power generation, diesel was used as the main source of fuel. The exponential rise in human population and the resultant growth in the transportation approaches have caused exhaustion of fossil fuel. Progressively, diminution of fossil fuel reserves distracted our consideration in the direction of finding an alternative fuel. Among the different alternative fuels, biodiesel was said to be a clean-burning fuel as it was biodegradable, renewable, and nontoxic. Here the avocado seed oil was transformed into methyl ester of avocado seed oil (A100) and experimented in a single-cylinder direct injection diesel engine. The physicochemical properties of A100 were examined in accordance with the ASTM biodiesel standard and equated with conventional diesel fuel. Strict emission regulations have prompted the researchers to lay emphasis on engine and fuel relevant techniques, thus leading to the investigation of cetane improver blended biodiesel and ceramic thermal barrier coating. In all, 1% of pyrogallol (PG) was used as a cetane improver with A100, which helps to achieve upgraded properties of the fuel. With the intention of using the accessible energy in the fuel, the ceramic thermal barrier coating was performed. The combustion chamber components were thermally coated with Yttria Stabilized Zirconia (YSZ) which causes decreased heat loss in the engine, and the accumulated heat was converted into beneficial piston work. Further, the experimentation was carried out with fuel blends to examine the performance and emission characteristics. From the acquired results, the application of PG enriched A100 in a YSZ-coated engine may be considered as a promising strategy for attaining improved engine characteristics.
