CFD Analysis of Combustion and Emission Characteristics of Karanja Oil in Diesel Engine: A Technical Review

The present paper investigates the performance and combustion characteristic of diesel engine running with karanja oil by using Computational fluid dynamics (CFD). Biodiesel is an alternative fuel of diesel is mentioned as methyl ester fatty acid from vegetable oils or animal fats. The objectives of the paper is to reduce higher viscosity of Pongamia pinnata (Karanja) oil using esterification followed by transesterification and to assess the performance and emission characteristics of diesel engine. The idea of using vegetable oils as fuel for diesel engines is an old technique. Appropriate crude oil fractions were reined with the arrival of petroleum to serve as fuel and diesel fuels and diesel engines evolved together. From the investigation it can be concluded that the CFD simulation is used to evaluate the combustion performance of the engine and biodiesel can be used as an alternative to diesel in a compression ignition engine without any engine modifications.
