| Abstract: | This study presents extraction of oil by mechanical
expeller and solvent extraction technique from jatropha and karanja seeds. Physico-chemical
properties of extracted oil, jatropha oil methyl ester (JOME) and karanja oil
methyl ester (KOME) were tested for their suitability in diesel engine.
Mechanical extraction efficiency with expeller developed by IIT Delhi was found
to be better (jatropha, 87%; karanja, 86%) as compared to traditional expeller
(67-69%). Induction periods (oxidation stability) at 110°C were found to be:
JOME, 1.76; and KOME, 2.24 h. Calorific value of JOME (38.65 MJ/kg) and KOME
(40.75 MJ/kg) was comparatively lower to base diesel (44.50 MJ/kg). Comparative
performance (brake thermal efficiency, brake specific fuel consumption) and
emission (CO, THC, NOx and smoke opacity) characteristics were tested in 4.4
kW, single cylinder, compression ignition engine with constant speed (1500
rpm). |
