1,4 dioxane, a new ad di tive al lows the splash blend ing of eth a nol in die sel in a clearso lu tion. The ob jec tive of this in ves ti ga tion is to first cre ate a sta ble eth a nol-die sel blended fuel with 10% 1,4 dioxane ad di tive, and then to gen er ate per for mance, com bus tion and emis sions data for eval u a tion of dif fer ent eth a nol con tent on a single cyl in der die sel en gine with and with out ther mal bar rier coat ing. Re sults show im proved per for mance with blends com pared to neat fuel for all condi tions of the en gine. Dras tic re duc tion in smoke den sity is found with the blends as com pared to neat die sel and the re duc tion is still better for coated en gine. NO x emis sions were found to be high for coated en gines than the nor mal en gine for the blends. The ox y gen en riched fuel in creases the peak pres sure and rate of pres sure rise with in crease in eth a nol ra tio and is still su pe rior for coated en gine. Heat release pat tern shows higher pre mixed com bus tion rate with the blends. Lon ger ig nition de lay and shorter com bus tion du ra tion are found with all blends than neat diesel fuel.

“…Both one dimensional (GT POWER) and computational fluid dynamics simulations of diesel engines with the combustion chambers insulated with TBC show increased fuel efficiency, 8,9 while experiments show varying results. In some experiments, fuel efficiency improvements of 1–6% have been achieved, 2,3,5 while in others no improvement or even a decrease in fuel efficiency were reported. 10–12 There are various possible reasons for the failure to obtain the expected benefits with TBCs in diesel engines.…”

“…Researchers have been studying the use of thermal barrier coatings (TBC) on different engine components to improve the fuel efficiency of diesel engines. [1][2][3][4][5] TBCs on combustion chamber components such as pistons, valves and cylinder heads have the potential to reduce heat losses from the combustion gases. 6 , 7 Lower heat losses from the combustion chamber may in turn lead to an increase in gas pressure and thus an increase in the work on the piston.…”

Thermal barrier coatings have the potential to improve the fuel efficiency of heavy-duty diesel engines by reducing heat losses. A method for in-situ measurement of heat flux from the combustion chamber of a heavy-duty diesel engine has been developed and was used to study the running-in behaviour of different thermal barrier coating materials and types of microstructures. The in-situ measurements show that the initial heat flux was reduced by up to 4.7% for all investigated thermal barrier coatings compared to a steel reference, except for an yttria-stabilized zirconia coating with sealed pores that had an increase of 12.0% in heat flux. Gd2Zr2O7 had the lowest initial value for heat flux. However, running-in shows the lowest values for yttria-stabilized zirconia after 2–3 h. Potential spallation problems were observed for Gd2Zr2O7 and La2Zr2O7.

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.
