“…CPO + Hex has a maximum HRR of 67 J/ °CA at 100% load, whereas CPO has a maximum HRR of 45 J/ °CA. Because hexagonal has a reduced viscosity and a high flame speed, ethanol addition in ternary fuel blends results in a significant increase in premixed combustion [13]. For CPO, it can be seen that primary combustion occurred during the diffusion phase.…”

Numerous Algae oils with low and medium viscosity were investigated as fuel for CI engines. However, high viscous algae oil has not been explored in detail as a replacement for diesel in CI engines due to operational problems and poor performance characteristics. Esterification of neat algae oil to obtain its biodiesel is a complex process. The biodiesel obtained also has viscosity nearly five times more than diesel viscosity. Hence, research efforts on CI engines using algae oil methyl ester are lacking, particularly in combustion characteristics. This work focuses on utilizing algae oil as a fuel in CI engines. Algae oil has more affinity for alcohols due to a higher percentage of ricinoleic acid which aids in forming a homogeneous mixture. Alcohols with better fuel properties improve the combustion capability of algae oils with low and medium viscosity. However, not much research has been carried out in alcohols with very high viscous algae oil. Hence, in this work, higher and lower-order alcohols were blended with algae oil in their neat form and their biodiesel with Al2O3 nanoadditives for performance improvement.

The field of nanofluids has received interesting attention since the concept of dispersing nanoscaled particles into a fluid was first introduced in the later part of the twentieth century. This is evident from the increased number of studies related to nanofluids published annually. The increasing attention on nanofluids is primarily due to their enhanced thermophysical properties and their ability to be incorporated into a wide range of thermal applications ranging from enhancing the effectiveness of heat exchangers used in industries to solar energy harvesting for renewable energy production. Owing to the increasing number of studies relating to nanofluids, there is a need for a holistic review of the progress and steps taken in 2019 concerning their application in heat transfer devices. This review takes a retrospective look at the year 2019 by reviewing the progress made in the area of nanofluids preparation and the applications of nanofluids in various heat transfer devices such as solar collectors, heat exchangers, refrigeration systems, radiators, thermal storage systems and electronic cooling. This review aims to update readers on recent progress while also highlighting the challenges and future of nanofluids as the next-generation heat transfer fluids. Finally, a conclusion on the merits and demerits of nanofluids is presented along with recommendations for future studies that would mobilise the rapid commercialisation of nanofluids.

“…As a result, it leads to better fuel-air mixing and a shorter ignition delay [16,18]. Since nanoparticles have a larger surface area, they facilitate the contact between fuel and air, helping fuel oxidation and reducing unburned hydrocarbons and particulate matter emissions [19]. Additionally, nanoparticles can increase the energy content of biodiesel blends, improving thermal efficiency in CI engines.…”

The use of biodiesel in compression ignition (CI) engines has great potential to reduce emissions and the dependence on fossil fuels. However, the complete adoption of biodiesel in CI engines is limited by several drawbacks. A promising solution to these problems is the addition of nanoparticles to biodiesel or diesel-biodiesel blends. Hence, this paper studies the impact of adding aluminum oxide (Al2O3) nanoparticles on the performance and emission characteristics of a diesel engine running on biodiesel and a mixture of diesel and biodiesel. Al2O3 nanoparticles were added at concentrations of 50, 100 and 150 ppm to biodiesel (B100) and a mixture of 50 % biodiesel and 50 % commercial diesel (B50). The results indicated an increase in fuel conversion efficiency and a reduction in specific fuel consumption. The highest fuel conversion efficiency was 26.5 % for B50 with 100 ppm of Al2O3, indicating an improvement of around 28.6 % compared to diesel fuel (B0). In general, CO emissions were reduced with the addition of nanoparticles, with a maximum reduction of 42.8 % for B100 with 50 ppm Al2O3 compared to B0. The highest reduction in NOX emissions was 30.3 % for B50 with 100 ppm Al2O3 compared to pure diesel B0.
