Experimentation was conducted on a single cylinder CRDI diesel engine using neat Jatropha methyl ester with
arbitrarily defined load on the engine (2.695kW) at rated speed 1550 rpm. CRDI system provides us the facility to change the
injection pressure and injection duration to commensurate with the load on the engine. In addition to the above facility, the
injection can be retarded or advanced with respect to the designed injection advance for the diesel fuel as mentioned in the
specification. In this paper, injection advance was taken up insteps of one degree viz.-220
, -230
and -240
. The experimental
study reveals that the injection advancement with the use of biodiesel is not totally fruitful except in some emission cases and
smoke levels. Hence, biodiesel with one degree retardation i.e.,-22
0
injection advance yielded better results in most of the
cases of performance making it suitable for the replacement of diesel fuel with the biodiesel.
