“…e BTE of biodiesel is more than in contrast with diesel, particularly in full load conditions [15]. From the graph, it is clearly understandable that the BTE has expanded with an increase in the blend proportion of mahua methyl ester (MME) biodiesel [16,17]. e BTE of blended mixes like JME15MME5, JME10MME10, and JME5MME15 at full load conditions are 22%, 23%, and 25%, slightly higher than diesel's 18%.…”

Depletion of fossil fuel assets makes it critical that we find biodiesel sources in the contemporary world. This work investigates dual bio-fuels of jatropha methyl ester and mahua methyl ester in various proportions, such as 15 : 5, 10 : 10, and 5 : 15. The performance and emission characteristics of JME15MME5, JME10MME10, and JME5MME15 blends of jatropha methyl ester and mahua methyl ester are suitable for diesel engines with little air pollution. Biodiesel blends with titanium dioxide nano-additives, such as jatropha methyl ester and mahua methyl ester, might be more efficient at the conclusion of the experiment, preserving fossil fuel assets for future generations. Performance parameters like BTE and SFC with different load conditions are analyzed for various blends, and then final results are drawn.

“…It is also to be noted that it has low emission of toxic gases like carbon monoxide (CO), Sulphur dioxide (SO 2 ). This is possible when the sulfur content in the fuel is less (Chukwuezie et al 2014) and is both economically and environmentally feasible. The best solution for this is using Biofuel as it helps in tackling the emission of greenhouse gases and also requires little to no change in the design of the transmission and combustion system (Mesri Gundoshmian et al 2021).…”

The use of biodiesel can reduce dependence on diesel and stabilize the economy when using internal combustion engines. CI engine's performance with biodiesel is substantially low but could be improved by emulsifying nano-additives with biodiesel. Magnesium-doped Calcium Oxide, a novel nanocatalyst is emulsified in its nano form with the Sapindus Trifoliatus biodiesel (STBD) at B25 blend (STBD25+Mg-CaO 30ppm) and tested in the CI engine. The performance results obtained are compared to the baseline values obtained using diesel, Sapindus Trifoliatus biodiesel (STBD25), and Sapindus Trifoliatus biodiesel blended with Cao nano additives (STBD25+30ppm CaO) in the CI engine. . A maximum biodiesel yield of 91.75% was achieved at 58°C, 73 min, a catalyst concentration of 4% (%w / %w) and a methanol: oil molar ratio of 15:1. From the comparison, it is revealed that (i) In-cylinder pressure found to be increased by 3.22%, 6.24% and 9.02%, (ii) HRR increases by 1.68%, 16.69% and 32.5%, (iii) BTE is found to be increased by 4.56%, 8.23% and 11.79%, (iv) UHC decreases by 21.12%, 6.06% and 11.43%, (v) CO decreases by 0.04%, 0.01% and 0.01%, (vi) Smoke decreases by 54.52%, 9.34% and 19.58%, compared with diesel, STBD25+30ppm CaO and STBD25. NOx released while using STBD25+Mg doped CaO in CI engine was observed to decrease compared with STBD25 and STBD25+CaO (by 10.72 % and 18.64 %) and increase compared with diesel (by 8.64%). Whereas an insignificant drop in NOx was observed while using STBD25+Mg doped CaO as fuel compared with STBD25+CaO and STBD25 in spite of a significant increase in HRR and BTE which might be due to the capture of excess oxygen by Mg during the combustion diffusion phase.

“…9 The soot nanostructure and its disorder are greatly influenced by the combustion conditions and the type of fuel additive. Improved engine performance and soot suppression potential have been reported so far by blending diesel with oxygenated biofuels such as bio-alcohols, 10 biodiesels from Jatropha, 11 Karanja, 12 palm oil, 13 and camphor oil. 14 Interestingly, each biofuel, depending on the chemical structure and functional groups such as oxygen content, degree of unsaturation, existence of five-membered cyclic structure, number of aromatic rings, and C/H ratio, significantly influences the soot formation rate and its oxidative reactivity.…”

Nanostructural Disorder and Reactivity Comparison of Flame Soot and Engine Soot Using Diesel and Jatropha Biodiesel/Diesel Blend as Fuels

Soot is a major anthropogenic air pollutant that affects human health and contributes to global warming. To understand its formation pathways and reduce emission, several flame and engine studies exist in the literature, though the fundamental differences in the characteristics of engine and flame soots are not well understood. This study presents a detailed comparative investigation of soot nanostructural properties and their relationship with the oxidative reactivity of soots from an engine and a diffusion flame using diesel and 20% Jatropha biodiesel/diesel blend fuels. X-ray diffraction, Raman spectroscopy, highresolution transmission electron microscopy, electron energy loss spectroscopy, and thermogravimetric analyses confirm that engine soot has greater primary particle diameter, higher concentration of loosely held aliphatics, greater degree of graphitized nanocrystallites with lower interplanar separation, longer fringe lengths, lower tortuosity, and greater resistance for oxidation than the flame soot, though the differences in several properties were minor. The effects of biodiesel addition to diesel on soot properties and sooting tendency were predicted very well with both flame and engine setup. Moreover, the enhanced soot oxidation in the combustor catalyzed by fuel-bound oxygen in biodiesel further reduces the nanostructural and reactivity differences between engine and flame soots. Though engine soot properties have more relevance to anthropogenic particulate matter, flame setups appear to be suitable for screening and studying the effect of fuel additives on the sooting propensity and physicochemical properties of soot prior to their testing and utilization in engines.
