The research investigates the combustion characteristics of a 4-stroke VCR Diesel engine by adding zinc oxide nanoparticles and using flax seed oil as an alternate fuel. The experimental setup includes testing several fuel samples. These samples contain traditional diesel as well as the beneficial of adding zinc oxide nanoparticles (ZnO NPs) to B20-grade flaxseed oil biodiesel together with dispersion (Triton X) and surfactant (CTAB) additives. B20 with 50 ppm ZnO NPs (B1), B20 with 50 ppm ZnO NPs and 50 ppm surfactant (B2), and B20 with 50 ppm ZnO NPs and 50 ppm dispersant (B3) were the three different mixes that were made. A comprehensive evaluation was conducted to determine how various additions affected the stability and combustion properties of the biodiesel. While flaxseed oil biodiesel and zinc oxide nanoparticles were used, engine operating characters significantly improved. According to the performance parameters, after improvements were made to the combustion characteristics such as cylinder pressure (CP), Net heat release rate (NHRR), Mean gas temperature (MGT) rises by 1.2%, 2.98%, and 10.22%, respectively.
