ESTER AS AN ALTERNATIVE FUEL IN
DIESEL ENGINE
“The right step in the
right path to limelight the world for a
Green fuel future in
the automobile industry”
On an average 95% of energy
requirements all over the world are derived from conventional energy sources
such as coal, natural gas and Petroleum. It is estimated that these reserves
are not going to last for not more than 50 years. Hence comes the problem of
energy crisis. In this context of fossil fuel crisis, the importance of
alternative fuel research for Internal. Combustion engines needs importance.
Vegetable oils – due to their properties being close to diesel fuel, may be a
promising alternative for its use in diesel engines. Bio-diesel is non-toxic,
biodegradable and renewable fuel with the potential to reduce engine exhaust
emissions.
The idea deals with the usage of raw
Jatropha curcas oil as well as blends of varying proportions of Jatropha Methyl
Ester (JME) and Diesel in a single cylinder diesel engine with and without
thermal barrier coated piston. Significant improvements in engine performance
and emission characteristics were observed for JME. The use of JME along with
diesel fuel has significantly reduced HC and CO emissions and to reduce NOx
emissions Hybrid fuel concept is followed.
