Due to the limited fossil fuel sources and the negative effects of their combustion pollutants on the environment, many countries around the world are currently using renewable energy sources such as solar energy, wind energy, biotechnology, hydroelectricity, heat ground, And ocean energy turned to their country to ensure energy development. Biodiesel is a type of biological fuel that is renewable and has similar properties to fossil diesel fuel. In this study, chlorella Vulgaris was selected as a source of biodiesel production and then produced and extracted in 5 stages from 200 ccs to 8,000 liters to observe and investigate semi-industrial cultivation apart from low-scale laboratory cultivation. After cultivating and separating it from the culture medium and drying it as a powder, the oil was produced from the powder and converted to biodiesel. Finally, the production of biodiesel was added to pure diesel fuel at 10 % and was tested in a vertical single-cylinder, four-stroke, natural breathing at 800, 500, and 1200 rpm and twice different times. The results of this study show that the amount of B10 fuel is slightly increased and then fixed, but the highest amount of pollution increase is 0.02, CO percentage, which is a small amount and the values are low. CO2 and NOx's b10 fuel reduced compared to pure diesel fuel. Most of the CO2 and NOX reductions were observed at 60 and 20 %, respectively. The B10 engine output was not much different from pure diesel fuel at minor loads, but for higher loads, the engine output increased slightly.
