| Περίληψη: | This study investigates the effects of biodiesel-diesel blends on the performance and emissions of a diesel engine operating at a fuel injection pressure of 220 bar and an injection timing of 23° BTDC under half and full load conditions. The analysis focuses on key performance metrics such as brake specific fuel consumption (BSFC), brake thermal efficiency (BTE), and emissions of unburned hydrocarbons (UBHC), carbon monoxide (CO), and nitrogen oxides (NOx), alongside combustion characteristics like rate of pressure rise (RoPR) and heat release rate (HRR). The results indicate that higher biodiesel content leads to increased BSFC and reduced BTE, with lower biodiesel blends (ALBD5) offering performance close to conventional diesel. Biodiesel blends reduce UBHC and CO emissions, with ALBD15 showing the most significant reductions, while NOx emissions increase with higher biodiesel concentrations. Combustion analysis reveals that biodiesel blends lead to smoother combustion, reducing peak pressure rise and HRR, thereby enhancing engine longevity. Overall, the study highlights the potential of lower biodiesel blends, especially ALBD5, as an effective alternative to diesel, offering a balanced solution for improved emission control and engine performance. Further optimization of biodiesel blends and engine parameters is necessary to maximize the environmental and performance benefits of higher biodiesel concentrations. [ABSTRACT FROM AUTHOR] |
