Abstract

The escalating global crises of fossil fuel depletion and emission threats are driving developed nations to adopt electric vehicles (EVs) for transportation. Despite their benefits, EVs pose challenges such as high costs, increased e-waste pollution, and concerns about electricity scarcity. Some countries are exploring hydrogen-based fuels for internal combustion engines but face issues related to hydrogen storage and safety. To overcome these challenges, research is focused on converting IC engines to low combustion technology, particularly reactivity- controlled compression ignition (RCCI) engines, and utilizing hydrogen-enriched biofuels. This study investigates the performance of RCCI engines using various ammonium hydroxide energy shares (30%, 35%, and 40%) as hydrogen carriers, combined with waste lather fat-derived biodiesel (WLFO) blended with 100 ppm of nanoparticles. Results indicate that a blend of 35%

ammonium hydroxide with 65% WLFO, compared to diesel in an RCCI engine, achieves significant reductions in nitrogen oxides (9.2%), hydrocarbons (27%), and smoke (26%), while maintaining comparable heat release rates, brake thermal efficiency, and brake specific energy consumption.
