14.4 Conclusion

Experimental investigations are conducted in a single-cylinder DI diesel engine using
different blends AME.
(a). Among the different proportions, A20 showed better performance and a significant reduc-
tion of exhaust emissions except NO x emission.
(b). Among the different proportions, A100 showed a maximum decrease of performance and
an increase of all exhaust emissions.
(c). All the proportions of AME increase the NO x emission. A20 has lower NO x emissions than
that of other proportions.
(d). Further, the A20 has a higher cylinder pressure and heat release rate than that of other
proportions.
Hence, it can be concluded that the A20 can be effectively used in diesel engines in terms
of performance, combustion, and emission characteristics without any modifications.
