The present research work involves the production of methyl ester from various vegetable oils like Karanja oil and application of with diesel blend as alternative fuel in a diesel engine to investigate on the engine performance and emission characteristics. The methyl ester is obtained by base catalyzed transesterification process which is then blended with diesel in various volume proportions. The use of additive in blended fuels reduces the ignition delay and combustion period of a diesel engine and lowers the sulfur and nitrogen oxide emissions. The investigation shows that the brake thermal efficiency increases upto 80% load and then decreases. The highest brake thermal efficiency is obtained for diesel. The brake specific fuel consumption decreases upto 80% load and then increases. The exhaust gas temperature increases linearly with load and is highest for pure biodiesel. The engine emission analysis with the above test fuels show that CO, CO2, HC and smoke emissions increase w...
Exergy and Energy Analysis of Diesel Engine Fuelled with Diesel and Diesel -Corn Oil Blends
Journal of Advanced Research in Fluid Mechanics and Thermal Sciences, 2019
Exergy and energy analysis of diesel engine fuelled with pure diesel and diesel-corn oil blends are the focus of this study. The analyses were carried out by using the results of experiments of fuels for different engine speeds. The obtained results revealed that the input exergy and energy of diesel-corn oil blends were lower than of that of conventional diesel at the same conditions. The exergy destruction is the major fraction of fuel exergy lost. Moreover, the exergy destruction increase with an increased engine speed for both conventional and diesel-corn oil blends. The destructed exergy of the test engine operating on diesel-corn oil blends was higher than that of conventional. It has been determined that exergertic efficiency and thermal decreases as the diesel-corn oil blends content in fuel increase so the highest values of exergertic efficiency and thermal efficiency were obtained for the diesel fuel. It was also observed that the exergertic efficiency value is lower than that of the thermal efficiency under the same conditions. Results also showed the diesel-corn oil blends can be used as a substitute for diesel fuel.

In the present work, an experimental investigation is carried out to evaluate the performance and emission characteristics of a twin cylinder diesel engine using different blends of Karanja oil and its methyl ester with fossil diesel under different load conditions. Both the fuels are blended with diesel in proportions of 10% and 20% each by mass and studied under various load conditions in engine. The study reveals that the performance parameters are very close to that of fossil diesel. However, the brake thermal efficiency and brake specific energy consumption of 20% blend of methyl ester are better than fossil diesel under certain loads. The emission characteristics are also studied and found that all blended fuels show better emissions than pure diesel except K20 which shows higher CO emission compared to base line diesel. Again, it is observed that blending up to 20% both in neat oil as well as bio-diesel can be accepted as a suitable fuel for use in standard diesel engines wit...
Investigation of Performance Characteristics of Diesel Engine Fuelled with Diesel-Kerosene Blends
__________________________________________________________________________________________ Abstract The techno-economic effects of diesel-kerosene blends on the operation of a direct ignition (DI) diesel engine were investigated using a stationary LD 20-D issan diesel engine. Standard experimental procedures were adopted. The values of pressure data of all petroleum fuel blends were higher when compared with that obtained when the engine was run on diesel fuel. However, due to the deterioration of combustion process caused by too much kerosene at 40% kerosene mixing, pressure data for 30% kerosene blend were higher than that at 40% kerosene blend from about 80 degrees after top dead centre. The exhaust gas temperature at 100% rated load was 16.7% higher at 30% kerosene blend as compared with that obtained with diesel fuel. Brake power increased with rated load for all the fuel blends. The brake power at 100% rated load was 19.8% higher at 30% kerosene blend than that obtained when the engine was run on diesel fuel. Specific fuel consumption at 100% rated load was 7.5% lower at 30% kerosene blend than that obtained when compared with diesel fuel. It was deduced that the use of 30% kerosene along with diesel fuel will result in 10% saving on fuel cost. __________________________________________________________________________________________
The Effects in Performance and Emissions of DI Diesel Engine Using Biodiesel (PPME) -Blends as Fuel
– In the present work biodiesel derived from non edible oil with diesel was used to study the performance of DI Diesel engine at 200 bar injection pressure and 1500rpm. Experiments were carried out with Pogamia Pinnata oil Methyl Ester (POME) and diesel blends in different proportions to reduce tail pipe emissions. Comparative study is conducted using diesel, bio-diesel and with various blends of biodiesel. POME is used (diesel, 20, 40, 60, 80, 100) with various percentages by volume for all loads (0, 3, 6, 9 and 12kg load). The performance of the engine is compared with neat diesel in respect of brake thermal efficiency, BSFC and exhaust emissions.
