Abstract

This study examines the effects of potassium alum, in crystalline (PAC) and powdered (PAP) forms, on diesel engine performance, combustion, and emissions. Diesel was blended with 50g, 100g, and 150g of PAC and PAP, held for 72 hours. Engine
tests showed that potassium alum improved Brake Thermal Efficiency (BTE) and reduced Brake Specific Fuel Consumption (BSFC), with optimal results at 100g. Combustion analysis indicated higher in-cylinder pressure, heat release rate (HRR), and mean gas temperature (MGT), enhancing fuel oxidation. Emission results showed reduced CO and HC emissions but increased NOx due to higher combustion temperatures. The 100g PAC and PAP blends proved most effective for balancing performance improvement and emission control, establishing potassium alum as a promising diesel fuel additive.
