  1. EFFECT OF ETHANOL CONCENTRATION ON EMISSION IN THE DUAL FUEL OPERATION OF JETROPHA METHYL ESTER AND ETHANOL IN A DIESEL ENGINE NAME OF THE GUIDE MR.S.VIJAYARAJ. ME. (PhD)., PROJECT MEMBER K. AJAI MITHUN FELIX(05ME01) S. BALA MURUGAN(05ME13) A. TAMILARASAN(05ME49) D.VIGNESH VARAN(05ME54)

  2. AIM Emission reduction on direct injection diesel engine fueled by methyl ester of non edible oils like Jatropha produced by transesterification process and with various percentage by concentration of ethanol in dual fuel mode by fumigation process.

  3. OBJECTIVE To develop a complete alternate fuel C.I engine by direct injection of bio-diesel and ethanol by fumigation technique with reduced emission. Then the project also addressed the issue of increased CO & NOx emission in dual fuel mode using dilution of ethanol concentration. Then to concluded that non edible oil can be used in transesterification form as methyl ester in dual fuel mode with ethanol using fumigation process which can produce better performance with reduced emission.

  4. REASONS FOR SELECTING THE TOPIC • Ethanol is one of the best tools to fight vehicular pollution, contains 35% oxygen that helps complete combustion of fuel and thus reduces harmful emission. • A country like India where agriculture is the main occupation and kirloskar engines are mostly used by the farmers for various applications. Our project focuses not only on bio-diesel but also on the ethanol for use in stationery diesel engines

  5. METHODOLOGY • Selection of non edible oil source. • To standardize the process of preparing methyl ester from various non edible oil. • To prepare and study of the properties of methyl ester • Design of fumigation apparatus in the conventional diesel engine • Conducting the performance and emission testing for dual fueled engine with direct injection of methyl ester and fumigation of various percentage of ethanol as supplementary fuel. • Conducting the performance and emission testing for the above dual fueled engine for various concentration of ethanol. • Result and discussion

  6. EXPECTATION OF PROJECT • Expecting properties of methyl ester is closes to diesel. • To obtain perfect combustion by fully using alternative fuel. • Reduce NOx emission by varying the concentration of ethanol. • Better performance and reduced emission using alternative fuel.

  7. APPLICATION • Better fuel economy with increased efficiency provides economical advantages over conventional fueled vehicle • It will reduce the emission of CO, CO2, NOx, HC, and smoke emission compared with diesel. • As Eco-friendly fuels are used in vehicles using this type of engine environmental degradation can be reduced. • It will increased agriculture productivity and cultivation of our country.

  14. FORMULA USED 1.Fuel consumption (FC),kg/hr. Fuel consumption was calculated using equation. FC = (10/Tavg) * ((x*sp.gr of BD+ y*sp.gr of ethanol)/1000) * 3600 Where Sp.gr = specific gravity of used Tavg =average time taken for 10cc of fuel consumption in sec x= Fraction of Biodiesel in the blend y=Fraction of ethanol in the blend 2.Brake power (BP),KW Brake power was calculated using eqn BP = calculated load/(*1000) 3.Specific fuel consumption (SFC) kg/kw-hr Specific fuel consumption was calculated using the eqn. SFC = (fuel consumption)/(Brake power)

  15. 4.Fuel power (FUP),kw Fuel power was calculated using the eqn. FUP = (FC*CV)/3600 Where FUP = fuel power in kw FC = fuel consumption in kg/hr CV = calorific value in kJ/kg 5.Brake Thermal Efficiency(%) Brake Thermal Efficiency was calculated using the equation BTH = (BP/FUP) * 100 Where BP = Brake power in kw BTH = Brake Thermal Efficiency in % FUP = Fuel power in kw

  16. 6.Indicated Power,kw IP = FRP + BP Where FRP = Friction Power in kw BP = Brake Power in kw 7.Indicated Thermal Efficiency(%) Indicated Thermal Efficiency = (IP/FP) * 100 Where IP = Indicated Power in kw FP = Fuel Power in kw 8.Mechanical Efficiency(%) Mechanical Efficiency = (BTH/ITH) * 100 Where BTH = Brake Thermal Efficiency in % ITH = Indicated Thermal Efficiency

  17. EXPECTATIONS AND APPLICATION • Better fuel economy with increased efficiency provides economical advantage over conventional fueled vehicles. • Reduced the emission of CO, CO2, NOX, HC and smoke emission compared with diesel. • As eco-friendly fuels are used in vehicles using this type of engine, environmental degradation can be reduced. • It will increase agricultural productivity by cultivation of oil bearing trees in Non arable land and giving impetus to sugar plantation for ethanol production which will increase the GDP of our country. • It can reduce the import of oil in-turn saving valuable foreign exchange.

  18. CONCLUSION Then to conclude that Jatropha oils can be used after transesterification as methyl ester along with ethanol by fumigation in dual fuel mode in a direct injection diesel engine for various percentage of ethanol with ethanol dilution which can produce better performance with reduced emissions.
