Evaluating the Effect of the EGR Rate on the Performance and the Emission of VCR Engine Operating on Jatropha Biodiesel Blends
Abstract: AbstractThe modern diesel engines running on biodiesel employ many techniques to encounter strict exhaust emission norms. Among the many techniques suggested to mitigate the NOX emission from the compression ignition engine, the Exhaust Gas Recirculation (EGR) system is being employed extensively. The EGR curtails the proportion of the oxygen in the mixture and lowers the flame temperature inside the cylinder. This research is intended to investigate the influence of the …
