‘Comparative analysis of diesel fuel types on engine performance and emissions’

This study explains the exhaust and combustion features of four types of diesel fuel using a direct injection diesel engine having 4-strokes and 1-cylinder. The investigation focuses on the performance of brake thermal efficiency (BTE), brake specific fuel consumption (BSFC), exhaust gas temperature (EGT), and gasses emissions like carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), and smoke opacity. Results show that diesel fuels of Types 3 and 4 display superior performance with increasing brake productivity up to 20% and reducing smoke emissions associated to other fuel types up to 40% highlighting their potential for enhancing engine efficiency and reducing environmental impact. These results show that diesel fuel Type 3 enhanced combustion and emission profiles in diesel engines presenting a valuable avenue for engine optimization and environmental compliance. © The Author(s) 2024.
