Summary: Dwindling air quality and fossil fuel reserves have prompted the need for alternative fuel sources. Biodiesel from animal/plant sources appears to be a viable substitute, although it has some drawbacks. One potential solution is the use of nano-based biodiesel in internal combustion engines, with the addition of Titanium oxide nanoparticles. This study shows that the nanoparticle-based blended biodiesel has significantly reduced emissions compared to diesel fuel.

Summary: The recently invented grasshopper optimization algorithm (GOA) was used to optimize the performance and emissions of a diesel engine running on a ternary fuel blend. Regression modeling was used to calculate the mathematical equations between the factors (ethanol ratio, biodiesel ratio, engine load) and the responses (BSFC, BTE, HC, CO2, NOx, CO). The results showed that the grasshopper optimization algorithm successfully maximized BTE and minimized the other responses, indicating its potential for improving engine performance and emissions.

Summary: Research and development in the internal combustion engine have been growing, and diesel engines have advantages in efficiency, power output, and reliability. Although observing diesel spray is complex due to its high-speed, high-pressure, and high-temperature conditions, some mechanisms have been explained and suggestions have been made. This paper comprehensively reviews the current status of theoretical diesel spray and modeling.

Summary: Diesel's ignition characteristics can be improved by using dibutyl maleate as an additive. Experimental results showed that the addition of dibutyl maleate increased in-cylinder pressure and ignition delay, while reducing combustion duration and thermal efficiency. The usage of dibutyl maleate also led to lower hydrocarbon and soot emissions, but increased carbon monoxide, carbon dioxide, and nitrogen oxides emissions.

Summary: This study investigates the combustion, performance, and emission characteristics of a multi-cylinder diesel engine using tea tree oil (TTO) blended with diethyl ether (DEE) and diesel. The results show that the TTO blends have higher cetane numbers but lower brake power and thermal efficiency compared to diesel. However, their carbon monoxide and hydrocarbon emissions are significantly reduced, while nitrogen oxide emissions are slightly higher.
