In the modern world, the rise of industrialization and motorization has significantly increased the use of internal combustion engines powered by petroleum products. This has led to the unsustainable exploitation and depletion of petroleum reserves. Consequently, the use of biodiesel-based biofuels, particularly those derived from microorganisms, along with gaseous fuel supplementation in internal combustion engines, has gained prominence. The urgent need to explore alternative fuels for combustion engines has become evident over the past few decades due to the rapid decline in fossil fuel reserves. This study examines the impact of hydrogen induction in the throttle body of a CI engine powered by blends of biodiesel from Chlorella vulgaris and mineral diesel in various proportions, without major engine modifications. The research aims to evaluate the performance, combustion, and emission characteristics of the engine when supplemented with hydrogen, biodiesel, and their blend B20. The experiments involve varying fuel compositions and engine operational parameters to assess their influence on efficiency, pollutant emissions, and combustion stability.
