“…Biodiesel fuel is an alternative fuel that can reduce the amount of pollution caused by diesel engines [12][13][14][15]. Recently, automotive researchers have taken an interest in the production of different types of biodiesel from edible and non-edible oil [16][17][18][19]. Many methods, including esterification, are used for biodiesel production.…”

“…The results indicated that significant improving of engine performance and decreasing of pollutants emission were obtained with preheated (at 100ºC) blend 50 and 20%. Pugazhvadivu et al [27] examined the influence of using mahua oil on the external performance of a single cylinder diesel engine. The output performance and pollutant emissions of the engine were studied to compare the use of diesel fuel and mahua oil.…”

The need for alternative fuel instead of conventional fossil fuels (diesel or gasoline) has recently increased for several reasons, including the expected shortage of petroleum fossil fuels and the production of pollution by transportation. Consequently, researchers are interested in finding new alternative fuels. At present, the number of studies on biodiesel as a compression ignition engine fuel has increased. Current studies are mainly concerned with studying the use of exhaust gas temperature to preheat biodiesel fuel before it enters the combustion chamber. A heat exchanger is designed to increase the temperature of the biodiesel fuel prior to the combustion process. The performance characteristics of diesel engines and the emission of pollutants resulting from this modification were investigated under different operating conditions, including different engine loads and speeds. The results showed clear improvements in engine performance, including improved output power, specific fuel consumption and pollutant emissions. The engine power and specific fuel consumption improvements as a result of preheating reached up to 1.3% and 8.27%, respectively. Pollutant emission also decreased obviously, with carbon monoxide and hydrocarbon emission decreases of 12.95% and 12.85%, respectively. However, the emission of nitrogen oxides increased by 4.39%.

“…Different preheated temperatures like 30 o C, 70 o C and 100 o C was used for the study and the results were compared with diesel fuel at 30 o C. They observed significant improvement in engine characteristics were noticed with the preheated Karanja oil. M. Pugazhvadivu and G. Sankaranarayana [8] Augustine et al [11] revealed lower CO, unburned HC and smoke produced were lower compared to diesel fuel when preheated cottonseed oil methyl ester was used as fuel in the direct injection diesel engine. This was attributed to the higher O 2 content of biodiesel which could improve the combustion process and heating process decreases the viscosity of biodiesel, thus improves the oxidation of biodiesel in the cylinder.…”

In the current scenario the driving forces for the research work on the alternative fuels are exhaustion of conventional fossil fuels, high petroleum diesel prices and increased environmental pollution. Biodiesel is one of the promising alternative fuels for petroleum diesel. Generally biodiesel is produced from seed oils and when they are produced from vegetable seed oils, it leads to scarcity of food oils. In such case the biodiesel produced from waste cooking oil (waste cooking oil methyl ester-WCOME)would be one of the best alternatives to the petroleum diesel. The higher viscosity of WCOME is one of the constraints to use directly in a diesel engine. Hence the present work reports the use of preheated WCOME in DI-CI diesel engine. The engine performance and emission characteristics were studied with preheated WCOME and compared them with no preheated WCOME and standard petroleum diesel characteristics. The results revealed that the considerable increase in brake thermal efficiency and decreased brake specific fuel consumption compared to without preheating. Improved emission characteristic was also obtained with preheated WCOME compared to without preheating. However, all the characteristics with preheated WCOME are slightly lower than petroleum diesel, but are very close to them. Hence preheated WCOME can be used in existing DI-CI engine to obtain similar characteristics as that of diesel without any modifications in the engine.

“…Most authors preheat the SVO such as to bring the physical properties closer to those of diesel oil. Most commonly, the oil temperature does not exceed 130 o C (Pugazhvadivu & Sankaranarayanan, 2010).…”

This work assess the technical viability of the use of straight vegetable oils as fuel for a compression ignition engine applied to distributed electric generation. The use of neat soybean, sunflower, and tung oils, three vegetable oils with potential for application in southern Brazil, was assessed. For this purpose, an electronically controlled conversion kit that preheats the fuel to a proper temperature was developed and adapted to a single-cylinder, naturally aspired, mechanically injected and controlled, compression ignition engine. The engine performance in a steady-state dynamometric cell, in terms of power, torque, specific fuel consumption, and emissions, using vegetable oils, was measured and compared to the performance for neat diesel oil. The neat diesel oil resulted in the highest brake power and the neat tung oil resulted in the lowest, with the relative difference among all fuels varying between 5 % and 20 %. However, the first law efficiency was highest for some of the blends tested, reaching 38 %, and increased for lower speed. The NO x and CO emissions both increased as the engine speed decreased, revealing the lack of complete combustion especially in the higher speed regime.
