Potential of EGR & CNG on performance & emissions of a CRDI engine

With the evolution of the increasing obligations of meeting and respecting the Emission legislations in the present millennium and towards society at large, diesel engine based technology had undergone a paradigm shift in its perspectives to meet the desired objectives of the necessary emission standards. To this end Common Rail Direct Injection (CRDI) has ushered in a new edge in diesel engine control systems. Where in complete freedom of injection timing, injection pressure and amount of fuel injection can be suitably varied to meet the expected standards of performance and emission. The present work is an exploratory effort to unearth the contingent benefits of such CRDI operation and also to investigate the possibility of using Compressed Natural Gas (CNG) and Exhaust Gas Re-circulation (EGR) technology as viable means in mitigating the pitfalls of the Soot-NOx-BSFC trade-off which has been an omnipresent dilemma in the context of diesel engines.
