In modern society where fossil fuel prices are increasing and environmental issues becoming more severe, biodiesel, as a new type of clean fuel, is receiving attention. Biodiesel has the advantages renewability, friendliness, good properties, demonstrating broad application prospects. However, use biodiesel also faces some challenges, such higher density kinematic viscosity, lower calorific value, etc. The nanoparticles in engines helps to achieve goal fuel. terms characteristics, increase cetane flash point improving combustion efficiency safety, but may affect combustion. can promote micro explosions secondary atomization improve cylinder pressure, heat release rate, brake thermal while reducing consumption. Nanoparticles reduce HC CO emissions, through oxygen reaction area, incomplete products. On contrary, CO2 emissions because better conditions oxidation reactions. For NOX temperature others emissions. Comparison shows that all offer varying degrees improvement engine performance provided by TiO2 significantly than other nanoparticles. future, synergistic effect multiple should be explored further achieving effects cannot achieved single nanoparticle.

Exploring the Effects of Synergistic Combustion of Alcohols and Biodiesel on Combustion Performance and Emissions of Diesel Engines: A Review

Energies, Год журнала: 2024, Номер 17(24), С. 6274 - 6274

Diesel engines are extensively employed in transportation, agriculture, and industry due to their high thermal efficiency fuel economy. However, the combustion of conventional diesel is accompanied by substantial emissions pollutants, including carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), dioxide (CO2), posing significant threats environmental quality. Biodiesel, as a renewable cleaner alternative fuel, can significantly reduce CO, HC, particulate matter (PM) its unique molecular structure. Nonetheless, lower calorific value poor cold-start performance limit application, while oxygen content may contribute increased NOx emissions. To address these limitations, researchers have proposed blending biodiesel with alcohol-based fuels such methanol, ethanol, or butanol create synergistic systems that optimize engine emission characteristics. This paper systematically reviews effects alcohol on characteristics blends engines. Studies indicate addition enhance improving atomization, extending ignition delay, increasing premixed efficiency. These enhancements result higher cylinder pressure, net heat release rate (HRR), brake (BTE), reducing brake-specific consumption (BSFC) some extent. Moreover, most studies report help smoke, but tend increase CO2 findings suggest certain cases, opposite results occur. The impact different types varies significantly, requiring comprehensive evaluation properties, latent heat, viscosity, content. Although appropriate demonstrates potential for optimizing emissions, excessive lead adverse effects, necessitating careful control ratio. Future research should consider mixing two more explore beyond capabilities single alcohols. Additionally, further focus compositions strategies varying operating conditions.
