Abstract:
Artificial intelligence-based technologies are rapidly advancing and significantly influencing the engineering sector, particularly in the automotive industry, through AI-driven neural network tools and Sankey diagrams. Meanwhile, the depletion of fossil fuels and rising emissions have pushed global efforts towards renewable and clean fuel solutions. Hydrogen, as a key clean fuel, has garnered considerable research interest. Combining hydrogen with biomass-derived fuels has gained attention due to its dual benefits of addressing biomass waste disposal and alleviating hydrogen storage and safety concerns. This study focuses on the production of aquatic plant oil (duckweed bio-oil) and its combination with hydrogen gas, evaluating their effects on the performance of a Reactivity Controlled Compression Ignition (RCCI) engine. The results revealed that the H40 blend demonstrated a 1% higher brake thermal efficiency (BTE) than diesel, along with emission reductions of 40% for HC, 6% for NOx, 27% for CO, and 14% for smoke. The results were further validated using an Artificial Neural Network (ANN) and a Sankey diagram. The ANN achieved low RMSE values (0.9965-0.9996) and MPAE values within 4%, while the Sankey diagram effectively illustrated energy distribution with minimal loss. These findings highlight the potential of hydrogen-enriched fuels for future internal combustion engines.

02:13Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.

02:17Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
