Abstract
The performance and emissions characteristics of a diesel engine running on several fuel combinations, including diesel, biodiesel, and fuel mixed with TiO2 nanoparticles, are assessed in this research on a diesel engine. The study investigates how performance and emissions are impacted when diesel and biodiesel are treated with 50 and 100 ppm of TiO2 nanoparticles under varied engine loads ranging from 25 to 100%. The BTE values for the mixed biodiesel fuels with TiO2 nanoparticles (B0Ti50, B0Ti100, B5Ti50, and B5Ti100) show an improvement over normal diesel (B0) and biodiesel (B5) fuels. The addition of TiO2 nanoparticles leads to reductions in brake specific fuel consumption (BSFC) of up to 8% with B0 and up to 14.29% with B5, and improvements in brake thermal efficiency (BTE) of up to 2% with B0 and up to 4.02% with B5. With regard to carbon dioxide (CO2) and hydrocarbon (HC) emissions, the use of TiO2 nanoparticles decreased emissions by up to 18.4% at the cost of nitric oxide (NO) emissions, which increased by up to 5.87%. The exergy performance coefficient (Exp) and sustainability index (SI) increased by up to 18.99% and 5.63%, respectively. The percentage changes showed enhanced engine performance, lower emissions, and improved energy conversion efficiency with the inclusion of nanoparticles. The results suggest fuel blends' advantages in terms of energy and the environment; however, it is also important to look at the economic feasibility and stability of TiO2 nanoparticles.
期刊介绍:
The Journal of Enhanced Heat Transfer will consider a wide range of scholarly papers related to the subject of "enhanced heat and mass transfer" in natural and forced convection of liquids and gases, boiling, condensation, radiative heat transfer.
Areas of interest include:
■Specially configured surface geometries, electric or magnetic fields, and fluid additives - all aimed at enhancing heat transfer rates. Papers may include theoretical modeling, experimental techniques, experimental data, and/or application of enhanced heat transfer technology.
■The general topic of "high performance" heat transfer concepts or systems is also encouraged.
