Characterization of biodiesel production (ultrasonic-assisted) from evening-primroses (Oenothera lamarckiana) as novel feedstock and its effect on CI engine parameters

In this research, Oenothera lamarckiana seed oil (OLO) has been investigated as a novel feedstock for biodiesel production in Iran. Ripe shrubs of Oenothera lamarckiana were collected from farms in Kohgiluyeh and Boyerahmad (around city of Yasouj) and seeds were extracted after drying of the stems....

Ripe shrubs of Oenothera lamarckiana were collected from farms in Kohgiluyeh and Boyerahmad (around city of Yasouj) and seeds were extracted after drying of the stems.
