The engine parameters of a diesel engine (using coated and uncoated pistons) operating with alumina additive chlorella vulgaris biodiesel blends were evaluated experimentally. The properties of test fuel samples were investigated using ASTM standards, and the composition of C. Vulgaris biodiesel was also examined using an FTIR report. A diesel engine’s performance and pollution characteristics were studied using different fuel samples such as diesel, CBD20, CBD20ANP with coated and uncoated pistons. The experimental results showed that the coated engine had a higher BTE (1.8-3.2 percent) and a lower BSFC (1.2-3.8 percent) than the uncoated engine. It is also identified that, exhaust emissions like as CO, HC, and smoke opacity have also been moderately reduced with the coated engine, while NOx emissions were slightly increased.
