“…They showed that the engine exhibition and burning cycle of the relative multitude of mixes were practically like No.2 diesel fuel, with 13% higher fuel utilization and a more limited start delay. Decreases in CO, HC, absolute particulate and 5.2% expansion NOx were likewise observed [27][28][29][30]. Ball processing is the technique for the creation of nano materials additives for biodiesel.…”

The fuel crisis throughout the world made many countries to be aware of their vulnerability to oil shortages. So many researches are still in progress and focus on the growth of bio fuel usage. In this regard, alternative fuels and the drivetrain play a major rule in critical emission issues. However, at the same time, enormous and vast number of vehicles have started to claim and place their heavy demand for alternative sources of fuel. Of course, gasoline and diesel, the conventional fuels will become scarce and much costlier. With a present known reserves and steep rise of demand and rate of consumption, hope of crude oil import is not going to last long. The CFD investigation is to find the combustion characteristics of the BioFuel with the various compositions of mixing with diesel, the Kirloskar IC Engine is taken for this research and the results of pressure, velocity, turbulence kinetic energy, temperature gradients, fuel combustions, oxidizers volume fractions also obtained from the CFD analysis results. CFD Analysis of Biodiesel combustion done in ANSYS Fluent. Software modeling of IC Engine done in CATIA V5 Software. Jatropha Methyl Ester (JME) and Mahua Methyl Ester (MME) are used for this research. Combustion characteristics in addition to emission parameters are assessed then a conclusion can be drawn.

“…This is due to a greater combustion temperature, which results in a faster energy conversion rate during combustion. This ultimately leads to better combustion and better conservation of fuel [19]. A significant 3% lesser BSFC has been observed for coated engines with diesel containing various volumes of aluminium oxide than diesel-employed coated engines at part load conditions.…”

“…The efficiency of a diesel engine covered with 0.1 mm thickness and 0.5 mm breadth of YSZ was enhanced by 6% in Ramalingam et al's experiment at all speeds and loads. The heat barrier coating is applied to the piston crown, piston, and cylinder head to fully use the finding [15][16][17] Because of its wide variety of physical qualities, such as a high coefficient of thermal expansion, a high Poisson's ratio, low thermal conductivity, and structural stability at high temperatures, YSZ was chosen as a feasible material for TBC I [18][19][20][21].…”

Environmental effects of vehicle exhausts from internal combustions engines which accounts for about 90% of vehicles on the roads is posing a major threat to environmental safety, and it only continues to surge at an alarming rate now than ever. With diesel engines being the most cost-effective prime mover readily available, their contribution to environmental pollution problems is humongous. The harmful contaminants from diesel exhausts are particulate matter (PM) and hydrocarbon and nitrogen oxides (NOx). So, efforts to curb environmental pollution are the need of the hour by making necessary improvements to reduce their local and global environmental impact. In this study, examine the effects of yttria- and alumina-stabilised zirconia coating on the piston head and cylinder lining of a single-cylinder diesel engine, as well as its performance and emissions. Various dosing amounts of nanoparticles of aluminium oxide were utilised as additives to diesel fuel in this study, on both coated and uncoated internal combustion engines. Many coated engine metrics improved significantly as a result of the research. The brake thermal efficiency has increased by 2.1 percent as compared to a conventional uncoated diesel engine, while brake-specific consumption has dropped by 3%, resulting in a reduction in dangerous chemicals.

“…Additionally, since biodiesel has a greater viscosity, emissions rose as the mix ratio was raised, resulting in a decrease in the burning effect [23]. When a 20% biodiesel blend is utilized, the quantity of CO and HC generated is decreased because the mixture is more oxygenated, which aids in full combustion [24][25][26]. With an increase in the ethanol ratio, emissions fall, with the lowest amounts of carbon monoxide and hydrocarbon emissions occurring at 15% of the ethanol ratio, which is mostly due to a faster rate of combustion.…”

Energy conservation and management have become critical industrial activities, since energy expenses account for a significant portion of production costs. This proactive strategy has had an effect on worldwide energy consumption trends. Integration of thermal barrier coatings into engine design is necessary to solve efficiency concerns, and this coating technology has the potential to increase engine power while lowering specific fuel consumption. In a similar line, biodiesel has been presented as a possible substitute to diesel since it is nontoxic and sourced from renewable energy sources. The present study aims to enhance the performance of a diesel engine via the use of a thermal barrier-coated piston that works on biodiesel mixes. Due to its outstanding thermal insulation qualities, yttria-stabilized zirconia is the preferred material for thermal barrier coatings. Brake thermal efficiency for B20E15 is about 4% better than diesel and for B20E05 and B20E15 is about 4.6% and 13.5% less fuel consumption. CO and HC emissions were reduced by 6% to 8% on average with the B20 blends. Biodiesel blends were compared to pure diesel in terms of performance and emissions, and the blend ratio was improved using a design of experiment tool.
