Predicting Ignition delay and HC emission for DI diesel engine encompassing EGR and Oxygenated fuels 2008-28-0050
Estimation of the ignition delay and concentration of exhaust emissions carries great importance in engine development process. In direct injection (DI) diesel engines, ignition delay has direct effect on startability, noise and pollutant formation. Hydrocarbon (HC) emissions are mainly due to the unburnt or partially burnt fuel leaving the engine exhaust system. In the present work, correlations have been developed for ignition delay and HC emissions. Satisfactory comparison of predicted and experimental values of ignition delay and HC emission under different operating conditions for various engines, widely varying in dimensions, method of aspiration and rated speeds validated the correlations. These correlations are useful as design tools for engine development.
