A Seminar on “Performance and Emission characteristics of CI Engine using Nano additive biodiesel blends with Exhaust gas recirculation” was organized by Dept. of Mechanical Engineering on 19.10.2020. Dr. A.Praveen has explained about performance of CI engine using nano additive biodiesel blends and how the exhaust gas recirculation occurs which is useful for students in their project work and to publish paper. About 54 students from Dept. of Mechanical Engineering were participated in the seminar.
