“…All of these GAP values indicate greater chemical stability of these compounds in relation to HCC; however, Sakurai et al carried out a synthesis and characterization of p -phenylenediamine derivatives, and Ritonga et al in a similar study found GAP values similar to those found for HCC. p -Phenylenediamine can be used as an antioxidant additive on NO x emissions and shows good results. − Breza and Puškárová carried out DFT studies of the effectiveness of p -phenylenediamine antioxidants, finding HOMO/LUMO values for some structures that indicate instability as well as HCC. Besides, Diab et al found a GAP value of 73.6 kJ/mol with p -phenylenediamine derivatives, which also indicates low stability.…”

Fossil fuels, which represent an important villain for the terrestrial ecosystem, are non-renewable sources of energy, which prompt many discussions about how long petroleum will remain available for use. As an alternative, new energy sources have been explored, including biofuels, such as biodiesel and ethanol. However, their use can raise some problems, such as lower storage stability associated with poor oxidation stability and lower energy availability, which affect consumption, emissions, and energy efficiency. In this context, a comprehensive study with structural description, theoretical calculations, and calorific power test was performed for a new halogen chalcone 4-(4-chlorophenyl)-1-[4-(2-oxo-2-phenylethoxy)phenyl]butan-2-one to understand its supramolecular arrangement and physicochemical properties. The structural description was carried out by X-ray diffraction with the contribution of Hirshfeld surfaces. The theoretical calculations were carried out using density functional theory with the contribution of calorific power determined by a calorimetric pump. All observed results characterize the new chalcone as a potential additive for biofuels.

The attributes of cost-effectiveness, reliability, consistency and better understanding, have made researchers prefer studying engine characteristics of IC engines fuelled with alternative fuels/diesel blends with computer simulation compared to conventional experimental study. For the first time, the study attempted to simulate combustion, performance, and emission characteristics of biodiesels from Canola and Sunflower oil domiciled in South Africa. The properties of biodiesel vary from one region to another depending on the local properties of the feedstock used for its production. In this study, a computer model-based C++ was used to evaluate the performance characteristics of biodiesel fuels produced from local South African sunflower and canola oil feedstocks. The developed model was validated using experimental results. The performance characteristics of biodiesel and biodiesel-diesel blends from these oils were tested in a Mercedes Benz OM 364A turbocharged four-stroke, four-cylinder direct ignition industrial diesel engine. Results show similar combustion characteristics for all the tested samples. Diesel shows a higher brake power and higher exhaust gas temperature than all the tested fuel samples. The brake thermal efficiency increases with the amount of biodiesel in the biodiesel-diesel blends. Biodiesel and its diesel blends show higher specific fuel consumption than diesel. In terms of emissions, nitrogen oxide emission was higher for biodiesel and its blends with diesel compared with diesel while smoke emission from biodiesel and its diesel blends was lower compared with diesel.

“…The results show 28.94% and 10.23% reduction in smoke opacity of B30 and B10 as compared to that of diesel at a load of 3.5kW respectively. Biodiesel blends have a lower smoke opacity as compared to diesel because of the presence of oxygen molecules in biodiesel, which enhance the combustion process resulting in decrease in smoke emissions (Prabhu & Anand 2015).…”

Fossil fuel resources are being depleted day by day and its use affects the environment adversely. Renewable energy is one of the alternate for sustainable development and biodiesel is one of the suitable alternate which can replace the diesel. The major hurdles in the successful commercialization of biodiesel are high feedstock cost and conversion technology to reduce viscosity. The choice of raw material and biodiesel production method must depend upon techno-economical view. There are some specific regions for different types of oil availability. It is therefore required to produce biodiesel from the mixture of oils to fulfill the requirements of energy demand in a particular country according to its suitability and availability of feedstock. Karanja and Linseed crops are abundantly available in India. Biodiesel was produced from a mixture of Karanja and Linseed oils by alkaline transesterification. In this experimental study, biodiesel blends of 10%, 20% and 30% were used with diesel in a diesel engine at a constant speed of 1500 rpm with varying brake powers (loads) from 0.5 kW to 3.5kW to evaluate brake thermal efficiency, brake specific fuel consumption, brake specific energy consumption, exhaust gas temperature, mechanical efficiency, volumetric efficiency, air fuel ratio and smoke opacity. They were compared with diesel and found satisfactory. BTE was found to be 28.76% for B10 at 3.5kW load. Smoke opacity was also found to be reduced with all blends. Smoke opacity was found to be reduced up to 10.23% for B10 biodiesel blend as compared to that of diesel at 3.5kW. Experimental investigation has revealed that biodiesel produced from a mixture of Karanja and Linseed oils can be successfully used in diesel engines without any engine modification and B10 was found to be an optimum biodiesel blend in terms of brake thermal efficiency.
