“…1 The high biodiesel production cost is suspected to limit the utilization. 2 The petro-diesel fuel price is 36.6% lower than biodiesel in the United States of America in January 2023. 3 Currently, the biodiesel industry is using vegetable oil as feedstock which consumes 75-88% of the total cost.…”

“…CaZrO 3 was coated over the engine's cylinder head and valves with a thickness of 0.35 mm above the layer of 0.15 mm thickness of NiCrAl were coated, and MgZrO 3 was used to coat the piston using the technique called atmospheric plasma spray. [ 19 ] Experiments were carried out on single‐ and double‐layered ceramic coatings of Al 2 O 3 %–40% TiO 2 , Al 2 O 3 %–30% MgO, ZrO 2 %–8% Y 2 O 3 , and ZrO 2 %–30% CaO from the experiment. A plasma spray coat is a bit more advantageous than a flame coat.…”

Herein, in order to estimate the optimized process specifications, an empirical study is done for biodiesel production, performance of standard and coated engine, combustion, and discharge aspects of Raphanus sativus (radish) biodiesel. Optimization process parameters of biodiesel production are done using the response surface method. The importance of this study is that optimized biodiesel production is used to improve the biodiesel properties and fatty acid content to find suitable vegetable oil as well as a new coating material for sustainable development of the country in the field of agriculture and ecological conditions. The mechanism used in this research work is a coating for internal combustion engine components done with partially stabilized zirconia, aluminum–20% silicon carbide (Al–20%SiC), and titanium dioxide that acts as a ceramic composite settled above the coating that has a thickness of 450 μm by the technique called air plasma spray for test purpose. To increase the performance of an engine and reduce the emission particles like smoke density, carbon monoxide, and hydrocarbon except NO x , the partially stabilized zirconia, aluminum–20% silicon carbide (Al–20%SiC) coated engine is used under various compositions of radish biodiesel and clean diesel. To reduce NO x , the engine operation is carried out along with the TiO2 coated combustion chamber steam, and water injection technique is added to overcome the NO x formation. From this study, the resulting factor shows that adding 25% radish biodiesel (B25) and 75% clean diesel shows a reasonable reduction in emissions with comparatively better performance and combustion in the engine under consideration.

Biodiesel, touted as a viable alternative to fossil fuels, has attracted interest due to its environmentally friendly nature, renewability, and high combustion yield. This study utilized K2O/RGO heterogeneous catalyst for biodiesel production through the transesterification of sunflower and waste cooking oils. Reduced graphene oxide (RGO) was prepared from graphite via the modified Hummers' method and potassium was subsequently deposited on it. The K2O/RGO catalyst was characterized using a variety of techniques, including FTIR, SEM, XRD, ASAP, Raman spectroscopy, and TEM. The study further investigated the impacts of the temperature, molar ratio of methanol to oil, catalyst dose and time; and optimized the process with the response surface method. The characteristics of biodiesel fell within the ASTM D 6751 and EN 14214 standard ranges. The K2O/RGO catalyst demonstrated reusability for up to four cycles. Maximum biodiesel yields of 98.54% for sunflower oil and 96.89% for waste cooking oil were achieved under operating conditions of 70°C temperature, 19.5 methanol to oil molar ratio, 2 wt.% catalyst dose, and 8.5 h time duration.
