“…When decanol is mixed with JFME, it lowers the in‐cylinder temperature and increases the viscosity of the blend, inevitably resulting in poor physical properties. [ 75 ] Thus, negative HRRs for all tested fuels can be observed initially. JFME is a complicated hydrocarbon fuel with different chemical and physical characteristics.…”

“…The HC is generated due to the cylinder's excessive leaning or rich zone and the quenching action. [65] HC emissions of diesel, JFO, JFME, D5, D10, D15, and D20 at maximum load are 75,81,63,55,57,59, and 69 ppm, respectively. Diesel produces more HC emissions due to a critical oxygen deficiency in their molecular structure, whereas for JFO, higher viscosity is the consequence.…”

Biomass‐based biofuel production is a promising solution to the decline of fossil fuels. Prosopis juliflora seed‐derived vegetable oil, known as Prosopis juliflora methyl ester (JFME), offers a potential feedstock for biodiesel. To enhance its properties, the addition of Decanol is investigated, a higher‐order alcohol similar to Diesel. Experiments are conducted on a 5.2 kW compression ignition (CI) engine using JFME blended with different decanol concentrations (5%, 10%, 15%, and 20%). Fourier‐transform infrared spectroscopy and gas chromatography‐mass spectrometry analysis confirm its compliance with fuel standards. The findings reveal that the 20% decanol blend (D20) achieves a brake thermal efficiency of 29.9% at full load, with reduced NO, smoke, and hydrocarbon (HC) emissions compared to diesel. D20 shows NO emissions of 1265 ppm, smoke opacity of 53%, and HC emissions of 69 ppm, while diesel records 1320 ppm, 69%, and 75 ppm, respectively. The CO emissions for D20 are 0.359 vol%, slightly higher due to decanol's higher latent heat of evaporation. Moreover, D20 exhibits improved combustion with a higher mass fraction burnt and faster heat release rates. These results indicate the potential of using JFME blended with 20% decanol as an alternative fuel for CI engines, offering higher performance and reduced emissions.

“…Higher loads result in more air and fuel mixing, forms stoichiometric mixture, which causes the fuel molecules to burn fully. This raises the temperature within the cylinder, which raises NO x levels . When the load is decreased, the surplus air mixes with the less fuel and creates a lean mixture, which results in incomplete combustion without further flame propagation, a lower cylinder temperature, and a reduction in NO x .…”

The ongoing depletion of the world’s fossil fuel sources and environmental damage has compelled the quest for alternative energy. Excellent characteristics of biodiesel include its renewable nature, safety, absence of sulfur, environmental advantages, and biodegradability, which can eradicate the above problems. In this study, algal oil was characterized to obtain the fatty acid profile, and the free fatty acid value of algal oil suggested a two-step process of esterification and transesterification for efficient biodiesel production. The performance and emission results of biodiesel and its blends (B10, B20, and B30) were investigated in a constant speed, single-cylinder, 4-stroke, 3.5 kW compression ignition engine at different loads for arriving at an appropriate fuel blend ratio. The response surface methodology technique is used to predict the ideal composition of microalgae–diesel using the experimental data with due weightage for the optimization criterion. The predicted blend ratio of B25 was tested on the engine and authenticated. The findings recorded an improvement in brake thermal efficiency to 31.42% and reduction in brake specific energy consumption to 9.82 MJ/kW h, unburned hydrocarbon to 85 ppm, carbon monoxide to 0.164% v/v, carbon dioxide to 4.115% v/v, nitrogen oxides to 691 ppm, and smoke opacity to 16.93%.

Biodiesel produced from different edible and non‐edible feedstocks is a viable alternative option for fueling a combustion engine. However, the widespread use of edible sources for biodiesel production may lead to food versus fuel controversy. Oil from non‐edible feedstock is best possible solution for problems that inhibits biodiesel production on commercial scale. This study presents the potential of different non‐edible feedstock for biodiesel production. Several aspects such as extraction technologies used for extracting oil from non‐edible sources and biodiesel production pathways from non‐edible feedstocks are discussed. The quality of biodiesel should be assured before its commercialization by different physical and chemical characterization techniques are used. In particular, the emission comparison of biodiesel derived from the different non‐edible feedstocks is discussed. Based on this study, the non‐edible feedstocks have the potential to produce biodiesel but still it has a long way to go. This is due to non‐edible feedstock is in the R&D phase and needs more research to eliminate additional treatment steps compared to edible feedstock for economic aspects. Furthermore, there has been a trade off in emission properties of biodiesels produced from non‐edible feedstocks which must be removed or evaluated for pilot scale investigations before commercialization.
