“…It was observed that BTE increased with the increasing of the brake power. The BTE improvement was due to the reduction in friction losses and increase in the brake power with the increase in load [44]. Among the fuel tested, the BTE was recorded for BT50 and standard diesel 21%, 22.8%, 25%, 26%, and 21.4%, 23.22%, 25.5%, 26.5%, respectively from no to full load.…”

In the present study, the performance of a new combination of biofuels jatropha biodiesel and turpentine oil for a diesel engine with a view to eliminate dependency on fossil fuel was observed. Jatropha biodiesel and turpentine oil are a high and low viscosity fuel combination with comparable heating values to that of diesel; this makes them conducive for in a diesel engine. The extensive experimental work was carried out on a Kirloskar make-single cylinder, constant speed, four strokes, 661cc diesel engine to examine the combustion performance and emission characteristics using the jatropha methyl-ester with turpentine oil and pure diesel. The engine was fuelled with the jatropha methyl-ester with turpentine oil (50% -50% on a volume basis) blend run on different loading conditions from no load, 35%, 65%, and full load. The blend of a dual biofuel was prepared with the help of a magnetic stirrer at 40°C in the presence of a surfactant span 80. The dual fuel blend was found to be superior to the diesel fuel in all aspects such as performance and emissions. In a further full load condition, a decrease of 2.9% in the brake thermal efficiency and reduction of 41.6%, 3%, and 4.43% in CO, NOx and CO2 respectively were recorded while HC was found to increased 29.31%.

“…Water-emulsified KOME showed a slight increase in sound-pressure level as compared to KOME. The use of water-emulsified fuel increases the rate of pressure rise [52,53], could also results in higher sound-pressure level as compared to the KOME. The phenomenon of micro-explosion may also be responsible for increased noise.…”

“…In [5], up to 20% water content, BSFC decreases as the water percentage in the emulsion increases. Some other references declare that water emulsified fuel has higher BSFC, and higher water content leads to even higher BSFC [7,9,11,12]. Figure 12 shows a comparison of the specific fuel consumption.…”

“…However, for small size high-speed engines, whose cylinder diameters are normally smaller than 140 mm, it is not practical to install a water injector on their cylinder head, therefore, for small size high-speed diesel engines, the only practical way is to use water emulsified fuel oil. There have been many research articles investigating the combustion performance and emission characteristics of diesel engines using water-emulsified light diesel fuel [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Some fundamental research on the combustion characteristics of HFO/water emulsions were carried out [19,20], but the effectiveness of emulsified HFO in high-speed diesel engines' performance was seldom researched.…”

Abstract:Using low price heavy fuel oil (HFO) in high-speed diesel engines is a practical way to reduce running costs. However, most high-speed diesel engines' fuel systems and combustion systems cannot adapt to HFO. This causes the problem of deterioration of combustion performance. In order to solve this problem, the authors have modified the fuel injection system and combustion system of a high-speed diesel engine to use HFO. In addition, reducing the viscosity of HFO is necessary before it is fed into the engine. Because heating apparatus are not feasible for high-speed engine users, light diesel was blended with HFO to reduce the fuel viscosity. The blend is called HFO-L. Meanwhile, for the purpose of further reducing NO x emissions and soot emissions, water-emulsified HFO-L, named HLW, was used on the research engine. When fueled with 10% water content HLW, the engine presented the same power performance and thermal efficiency as the baseline engine fueled with light diesel. Due to the low price of HFO, the fuel economy of the engine was greatly improved. In addition, fueling HLW led to a considerable reduction of the engine's NO x emissions compared with the baseline engine.
