“…The engine operating parameters influenced the particle size distribution: higher load lowered the proportion of smaller diameters while higher engine speed reduced the particle diameters. Yildiz et al [41] investigated the production of renewable biofuel from WCO from the standpoint of waste to fuel per energy. Biofuel produced from WCO has higher viscosity and density than diesel since it contains fatty acids.…”

“…Aside from the emission outcomes, biofuel has a lower "soot concentration" value than diesel fuel. In relation to total particle concentration, biofuel has a substantial advantage over diesel fuel for a healthier and more sustainable environment [41]. Balasubramanian et al [42] analyzed the engine emission characteristics of WCO and its blend with biodiesel.…”

With the rising consumption of energy comes the challenge of the depletion of fossil fuels. Fossil fuels are non-renewable and finite energy sources with increasing energy demand as a result of the rise in human population and industrialization. This concern has led researchers to seek alternative energy sources that are both economically, technically viable, and environmentally beneficial. Biodiesel is considered an alternative source of energy supply. It is non-toxic, biodegradable, carbon-neutral, and ecologically friendly. However, the high cost of producing biodiesel from feedstocks impedes its commercialization. Hence, WCO used in the production of biodiesel helps to reduce the overall cost of production. The characteristics of the performance, emission, and combustion of the biodiesel produced from the transesterification of WCO are reviewed in this study. The molar ratio of methanol to oil, the concentration of the catalyst, reaction temperature, and time were used to investigate the optimization parameter required in the synthesis of biodiesel from WCO. The number of times the catalyst can be reused while maintaining a good catalytic activity in biodiesel production was also studied. The optimization models and techniques for the prediction of biodiesel yield were also studied.

“…The worldwide voice of cutting down the release of greenhouse gases is pushing the stringent regulation of CO 2 emissions and the development of alternative fuel [1][2][3][4][5][6][7][8][9][10][11] internal combustion engine technologies. Natural gas has been widely used as an alternative fuel for internal combustion engines for decades, and the number of natural gas engine owners is growing rapidly in recent years.…”

The combustion and emission characteristics as well as the economic performance of partial oxidation fuel reforming (POFR) natural gas engines were investigated by adjusting the fuel reforming ratios and the engine load. The performance of the POFR engine with a 12% fuel reforming ratio was compared with that of the original engine. The results showed that the fuel-partial-reforming was effective in reducing the cycle-to-cycle variations over the whole range of the operating conditions. The THC and NOX emissions decreased at almost all operating conditions, but showed different decreasing trends at different loads and equivalence ratios, while the CO emissions increased at all operating conditions. It was found that reducing the advancement of ignition timing of the POFR-engine can further reduce the gaseous pollutant emissions without reducing the economic performance of the engine. In conclusion, blending reforming gas improved the overall performance of the natural gas engine at low to medium load conditions.
