Abstract:

Abstract: The experimentation was carried out on Direct Injection Diesel (DI-diesel) engine to study the performance and emission characteristics under various load conditions using additives of nanoparticles (AAONF). To produce the fuel mixtures, an ultrasonic sonicator was used. Three blends were tested: the first blend (D93+E5+S2) consisted of 93% diesel, 5% ethanol, and 2% surfactant; the second blend (D88+E10+S2) consisted of 88% diesel, 10% ethanol, and 2% surfactant; and the third blend (D83+E15+S2) consisted of 83% diesel, 15% ethanol, and 2% surfactant. In addition, the chosen blend was supplemented with 50 and 75 parts per million of AAONP (AAONP50 and AAONP75, respectively).The Investigation revealed that the third blend, consisting of D83+E15+S2, provided the best performance, emission, and combustion characteristics. Furthermore, it has been discovered that there was an increase in break thermal efficiency and decrease in fuel consumption when engine is operated with AAONP. At full load, the nitrogen oxide emissions for the blend augmented with AAONP75 were comparable , this study suggests that the use of fuel additives, particularly AAONP, can have a significant impact on the performance and emissions of DI-diesel engines. The findings also highlight the importance of optimizing fuel blends to achieve the desired balance of performance and emissions characteristics. drop
