Three dimensional modelling of a dual fuel compression ignition engine

Three dimensional modelling of a six cylinder, turbo charger diesel engine was done. After the tuning of the result get from computational model with experimental results, dual fuel engine modellin was done. In dual fuel engine, the base fuel is the natural gas and it is assumed that it mix with air homogeneously at inlet manifold. In this context, firstly, different natural gas supplement ratios were studied and compared with the base diesel with regard to performance and emissions. Secondly, at different EGR ratio, dual fuel engine's performance and emissions compared with base diesel. The last one, hundred percent natural gas, hundred percent diesel and dual fuel engine which has constant suplement ratio were compared each other with regard to performance and emissions.
