“…CNT nanotubes can promote finer fuel atomization during the injection process. Finer fuel droplets result in better air-fuel mixing, leading to more efficient and complete combustion, potentially contributing to a higher cetane number [26]. he NP addition to the base fuel corresponds to a greater heat release rate due to the augmentation of the energy content on the fuel [24].…”

Biofuel production and its properties improvisation are the wide areas of research in internal combustion (IC) engines. This research derived biofuel from industrial chicken waste. Nanofuels were produced in this study by adding 40 nm-sized nanoparticles of carbon nanotube (CNT) and manganese oxide (MnO) with a variation of 100 to 200 ppm to the derived oil. Four fuel blends (biofuel (B), B with CNT, B with MnO, and B with CNT+MnO) were compared to the performance of diesel fuel in a 3.5 kW CI engine. The combustion process (peak pressure and heat release), brake thermal efficiency (BTE), and exhaust emissions (CO, HC, NOx, and CO2) were used as parameters to evaluate the fuel’s performance. The result revealed that nanofuel outperformed both diesel fuel and biofuel. The addition of 200 ppm CNT in biofuel enhanced the fuel properties, resulting in higher BTE by 28% and 9.7% compared to diesel fuel and biofuel. The CNT-biofuel also generated fewer emissions compared to diesel fuel by 26%, 9.4%, and 25% for NOx, HC, and CO gases respectively.

“…Notably, B20M100, with the highest MWCNT concentration, is found to be less effective due to MWCNT clumping. The study highlights the need for further research on MWCNTs’ impact on fuel injection system wear, potential nanoparticle emissions from engine exhaust, and a deeper understanding of MWCNTs in diesel engine combustion chambers . The study investigated how titanium dioxide (TiO 2 ) nanoparticles and ethanol impact a diesel engine’s performance and emissions using various fuel blends.…”

This study investigates the utilization of an α-MnO 2 /nanocarbon ball (NCB) additive to enhance the performance of second-, third-, and fourth-generation biodiesels (SSGB, PVB, and GMCB). Various tests including XRD, XPS, TEM, HRTEM, BET, torque and power measurements, EGT, BTE, emissions analysis (CO 2 , CO, HC, soot, and NOx), and BSFC were conducted. The combination of GMCB5N50 with α-MnO 2 / NCB yielded the highest torque (35.77 N m) and power (6.47 kW), indicating an improved engine performance. GMCB5N50 exhibited efficient combustion with a peak pressure of 76.04 bar. The nanoadditive also demonstrated significant reduction in BSFC, achieving up to 34% improvement in fuel efficiency. When GMCB20N50 was used, the highest BTE values were observed, reaching approximately 39.5%. EGT values for GMCB5N50 were only slightly elevated compared to pure diesel. Notably, GMCB20N50 showcased substantial decreases in emissions, including carbon dioxide (CO 2 : 55% reduction), carbon monoxide (CO: 35% reduction), hydrocarbons (HC: 58% reduction), and soot (98% reduction), indicating a promising direction for the development of low-emission alternative fuels. The investigation of the effects of the oxygen lattice, surface area, and oxygen adsorption on engine performance and emission reduction revealed their positive contributions. These findings highlight the potential of the studied α-MnO 2 /NCB additive for improving biodiesel performance and advancing the development of sustainable and environmentally friendly fuels.
