  2. 2. INTRODUCTION Today, Automobile industries are focusing on global warming and saving non-renewable sources.  Bio diesel is one of the best solution of above mentioned problems.  Since it is a renewable energy, produce less emission and it is successfully implemented on existing systems (cars).
  3. 3. What is Biodiesel? Biodiesel:  An low-emissions, high lubricating alternative diesel fuel produced from veg.oil / animal fats  Non-toxic, Biodegradable  Can be combined at any level with petroleum diesel to fuel diesel engines.
  4. 4. Oil or Fat  Soyabean Alcohol Methanol(common)  Corn Ethanol  Canola  Cottonseed Catalyst  Sunflower Sodium hydroxide  Beef tallow Potassium hydroxide  Used Cooking Oil
  5. 5. Convert “3-headed” Oils into Hydrocarbons chains similar to petroleum diesel… = + Veg. Oil (soya oil), Three fatty acid chains attached to glycerol. Methanol 3(CH3OH) + Typical “Biodiesel” Methyl-Ester Cetane – typical of petro-diesel Byproduct: Glycerol aka Glycerine
  6. 6. Biodiesel Blends Biodiesel Petroleum diesel B100 = 100% biodiesel B20 = 20% biodiesel + 80% B100 B20 petroleum diesel B10 = 10% biodiesel + 90% petroleum diesel B5 = 5% biodiesel + 95% petroleum diesel B2 = 2% biodiesel + 98% petroleum diesel B10 B5 B2 0 50 100
  7. 7.  High Cetane no. (avg. over 50)  High Lubricity, even in blends as low at 1-2%  High Energy Balance (3.2 to 1)  Low Agriculture Inputs: Soybeans  78% Life Cycle CO2 Reduction  Renewable, Sustainable  Domestically Produced  Reduces HC, PM, CO in existing diesel engines  Reduces NOx in boilers and home heating
  8. 8. Bio diesel is environmental friendly. It can help reduce dependency on foreign oil. It helps to lubricate the engine itself, decreasing engine wear. It offers similar power to diesel fuel. It is safer than conventional diesel. It can be made from waste products. It can be made at home easily.
  9. 9. Its storage for long period is not suitable for engine operation. It becomes gel in cold weather. It has water content. (Hygroscopic) It degrades rubber. It has higher (10%) Nox emissions. It decreases horsepower. (25%)
  10. 10. B100 = 100% Biodiesel B20 = 20% BD + 80% PD B100 Electric Diesel Hybrid B20 Ethanol 85% Diesel LPG CNG Gasoline 0 20 40 60 80 100 120 140 160
  11. 11. Effect of biodiesel on engine performance Power performance:Contents of Biodiesel Fuel • B-100 • B-20 • B-0 P.P. (Due to lower heating value) 100% Properties of Biodiesel P.P. • Heating Value • Viscosity • Lubricity
  12. 12. Durability Performance:Fuel • B-100 • B-20 • B-0 Durability (It is reactive in nature) 100% Economy Performance:• In order to compensate loss of heating value more amount of biodiesel fuel consumption takes place. • The difference in fuel consumption of diesel & pure BD was 18.5% in mass & was reduced to 13.5% by volume because of higher density of BD.
  13. 13. Biodiesel is least-cost-strategy to comply with state and federal regulations. Use of biodiesel does not require major engine modifications. The only thing that changes is air quality. Biodiesel has positive attributes such as increased cetane, high fuel lubricity & high oxygen content.
  14. 14.      Biodiesel contains fewer aromatic hydrocarbon: benzofluoranthene: 56 % reduction; Benzopyrenes: 71 % reduction . Biodiesel reduces emissions of carbon monoxide (CO) by approximately 50 % and carbon dioxide by 78 % on a net lifecycle basis. Biodiesel is biodegradable and non-toxic posing no threat to human health. Biodiesel reduces by as much as 65 % the emission of small particles of solid combustion products. Biodiesel has higher cetane rating than petro diesel .
  15. 15.  The use of biodiesel in a conventional diesel engine results in substantial reduction of unburned hydrocarbons, carbon monoxide, and particulate matter compared to emissions from diesel fuel.  The ozone (smog) forming potentials of hydrocarbons is less than diesel fuel.  Sulfur emissions are essentially eliminated with pure biodiesel .
  16. 16.  Parameter will studied :• Different vegetable oils used as fuel in C.I.Engine.  Required equipment's:• Engine test ring • Gas analyzer • Temp indicator • Techo meter • Pressure sensors • Computer  To calculate:• Brake Thermal Efficiency • Brake specific fuel consumption • Thermal efficiency • Mechanical efficiency
