Environmentally Friendly Performance Enhancement in Diesel-Biodiesel Fuel Blends with CQD Nanoparticles

Researchers are developing new methods to enhance the performance of diesel engines and reduce their emissions. Especially alternative fuels like biodiesel provide better performance but face challenges such as high density, viscosity, and increased NOx emissions. To solve this issue, the properties of biodiesel produced by the microwave method are being improved, and more efficient chemical reactions during combustion are being achieved. Additionally, nanoparticles are drawing attention as a promising solution to enhance the combustion performance of diesel and biodiesel blends. These nanoparticles, with high surface area, increase the combustion heat, enhancing the efficiency of the combustion process and helping to reduce emissions. Thus, harmful emissions like carbon monoxide (CO), hydrocarbons (HC), and smoke decrease, while engine performance increases. Recent research shows that adding nanoparticles to fuel blends offers significant benefits in increasing combustion efficiency and reducing environmental impacts.

Carbon Quantum Revolutionizes Diesel Biodiesel Blends

The study aims to enhance engine performance and reduce emissions by integrating carbon quantum (CQDs) into diesel-microwave-produced corn biodiesel (D80MCB20) blends. By examining effects such as cylinder pressure, heat distribution, specific fuel consumption (SFC), CO, CO2, HC, NOx, and soot emissions, the study focuses on the potential benefits of CQD nanoparticle additives. Observations show that the inclusion of CQDs in D80MCB20 leads to increased cylinder pressure compared to traditional fuel blends and demonstrates promising improvements in combustion performance. While the high density and viscosity of biodiesel typically worsen spraying and combustion processes, the CQD nanoparticle addition in D80MCB20 effectively counters this, proposing a new approach to optimize engine efficiency and emission control.
 

CQD Nanoparticles Enhance Performance and Reduce Emissions in Diesel Biodiesel Blends

The research reveals that adding carbon quantum (CQD) nanoparticles to diesel and microwave corn biodiesel blends significantly increases engine efficiency while reducing emissions. High CQD concentrations raise cylinder pressure and improve the combustion performance of the fuel. Additionally, carbon monoxide (CO), hydrocarbons (HC), and soot emissions are significantly reduced. The results show that CQD has the potential to enhance engine efficiency and reduce environmental impacts. However, it is emphasized that further research is needed on the mass production and cost-effectiveness of CQD.
