- Abstract
- This study investigated diesel/1-butanol blended fuels' combustion performance and emissions using a naturally aspirated single-cylinder diesel engine at varying speeds and blending ratios. Results showed improved brake thermal efficiency with butanol blends compared to pure diesel, while brake specific energy and fuel consumption slightly decreased. Higher butanol ratios increased NOx but reduced CO and smoke emissions. CO2 emissions peaked at 1,600 rpm, dropped at 2,000 rpm, and rose again above 2,400 rpm due to varying combustion efficiency and fuel consumption. While demonstrating potential for maintaining performance and reducing CO/smoke emissions, addressing increased NOx requires exhaust gas recirculation and combustion optimization.
