Emission and performance characteristics of blended biodiesel

  1. 1. EXPERIMENTAL STUDY OF BLENDED BIODIESEL BY SHYAM KUMAR S7 MECHANICAL
  2. 2. MAIN JOURNAL
  3. 3. 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).
  4. 4. WHAT IS BIODIESEL? Biodiesel:  Biodiesel refers to a vegetable oil - or animal fat- based diesel fuel consisting of long- chain alkyl (methyl, ethyl, or propyl) esters.  Non-toxic, Biodegradable  Can be combined at any level with petroleum diesel to fuel diesel engines.

  7. 7. ADVANTAGES • Bio diesel is environmental friendly. • It can help reduce dependency on foreign oil. • 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.
  8. 8. • It gives out more nitrogen oxide emissions. • It can only be used in diesel-powered engines. • Higher viscosity. • Poor cold flow properties DISADVANTAGES

  19. 19. CONCLUSIONS • Diesel –biodiesel –diethyl ether blend(BDET) and BDE shows better stability in diesel engine without modification. • BSFC of BDET is slightly lower because of high volatility. • BDET and BDE have high oxygen content than B20,shows excellent ability to eliminate smoke emissions. • NOx emission will be higher in BDE but HC emissions will be low in comparison with B20.
