بررسی تجربی اثر غلظت نانوذرات بر عملکرد موتور اشتعال تراکمی با سوخت دیزل/بیودیزل از دیدگاه قانون اول و دوم |

| چکیده فارسی مقاله |
Reducing fossil fuel sources together with tighter environmental laws to control the engine exhaust emissions make the use of cleaner and renewable fuels inevitable. Therefore, the use of biodiesel fuel as a strategy to conserve energy and reduce emissions is becoming increasingly important in engines. On the other hand, biodiesel fuels increase NOx emissions in the engines, which necessitate the use of water additives to reduce the combustion temperature. To compensate for the negative effect of water addition by reducing combustion quality and thus reducing thermal and exergy efficiency, the use of metal-based nano-particles additive can be a reliable solution. In this study, the effect of adding different concentrations of nano-particles on improving efficiency of the first and second law as well as fuel consumption of a single-cylinder engine with different fuel combinations with BXWYNZ formula (diesel fuel with X% biodiesel mass, Y% water mass% and Z ppm nano-particles), has been studied experimentally. The results of this study show that adding 60 ppm nano-particles to B0W5 will improve about 3% efficiency in the first law and 2.5% efficiency in the second law compared to diesel fuel. These values were about 4% and 3.8% for 90 ppm nano-particles, and 5% and 4.7% for 120 ppm nano-particles, respectively. In addition, based on the experimental results, the B15W5N120 has 7.5% higher first-law efficiency and 7% higher second-law efficiency than pure diesel fuel.
