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. 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. 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. • It gives out more nitrogen oxide emissions.
• It can only be used in diesel-powered engines.
• Higher viscosity.
• Poor cold flow properties

18. Results and Discussion

22. 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.
