We confined the formation and characterization of heterogenous nano-catalysts and then used them to produce biodiesel from the novel non-edible seed oil of Prunus aitchisonii. P. aitchisonii seeds’ oil content was extracted at about 52.4 ± 3% with 0.77% FFA. Three different heterogenous nano-catalysts—calcined (CPC), KPC, and KOH-activated P. aitchisonii cake Titanium Dioxide (TiO2)—were synthesized using calcination and precipitation methods. The mentioned catalysts were characterized through XRD, SEM, and EDX to inspect their crystallin dimension, shape, and arrangement. Titanium dioxide has morphological dimensions so that the average particle size ranges from 49–60 nm. The result shows that the crystal structure of TiO2 is tetragonal (Anatase). The surface morphology of CPC illustrated that the roughness of the surface was increased after calcination, many macropores and hollow cavities appeared, and the external structure became very porous. These changes in morphology may increase the catalytic efficiency of CPC than non-calcined Prunus aitchisonii oil cake. The fuel belonging to PAOB stood according to the series suggested by ASTM criteria. All the characterization reports that P. aitchisonii is a novel and efficient potential source of biodiesel as a green energy source.

“…The problems of crude vegetable oils can be solved to some extent, if these oils are chemically modified (esterified) to biodiesel. Studies were made with biodiesel on CE [6][7][8][9][10]. They reported from their investigations that biodiesel operation showed comparable thermal efficiency, decreased particulate emissions and increased nitrogen oxide (NOx) levels, when compared with mineral diesel operation.…”

Biodiesels derived from vegetable oils present a very promising alternative for diesel fuel, since they have numerous advantages compared to fossil fuels. They are renewable, biodegradable, provide energy security and foreign exchange savings besides addressing environmental concerns and socio-economic issues. However drawbacks associated with biodiesel of high viscosity and low volatility which cause combustion problems in compression ignition engines, call for low heat rejection (LHR) engine. LHR engines have significant characteristics of higher operating temperature, maximum heat release, and ability to handle low calorific value fuel. Investigations were carried out to determine exhaust emissions with LHR engine and conventional engine (CE) with crude cotton seed biodiesel. L H R e n g i n e consisted of an air gap insulated piston, an air gap insulated liner and ceramic coated cylinder head with different operating conditions of normal temperature and preheated temperature cottonseed biodiesel with varied injector opening pressure. Nozzle testing apparatus was used to increase injector opening pressure. Particulate emissions and oxides of nitrogen were determined with sophisticated analyzers at full load operation of the engine. LHR engine reduced pollutants at higher injector opening pressure at preheated temperature of biodiesel in comparison with neat diesel operation on CE.

“…After went through the experimentation of the different researchers it was cited that the performance was poor, high viscosity, low volatility ,combustion chamber deposits ,fuel system deposits. The other major draw backs that they were found decrease in brake power and increased exhaust emissions [1][2][3][4][5][6][7][8]. Fatty acids presence in the increases the exhaust emissions from the engine.…”

Vegetable oils are the only fuels, can be substituted as alternative to overcome the shortage in developing countries. Using non-edible oil like crude jatropha as alternative, waste land can be effectively cultivated and employment can be improved. Experiments were Initiated on semi adiabatic diesel engine with super charging air through the intake manifold using crude jatropha oil with varied injection pressure and varied injection timing to study the performance of the engine. Tests were also conducted using diesel fuel in diesel engine and engine with high grade heat rejection combustion chamber at recommended injection timing at 270 bTDC with super charging air using crude jatropha oil. Improvement in performance was found with super charging when comparing with natural aspiration.
