On the other hand, Spark Ignition (SI) engines are not able to match the thermal efficiency of diesels, as well as their low emission of carbon dioxide (CO2): therefore, it is highly desirable to identify cost effective solutions that permit to overcome the limits of Diesel engines, in particular soot emissions, while maintaining all the above mentioned advantages. Dual fuel combustion, combining Natural Gas and Diesel fuel, is a well proven technique for reducing soot emissions, while maintaining, or even increasing fuel efficiency. Moreover, this technology can be directly applied to existent Diesel engines with a few hardware modifications. Obviously, to achieve the best results, a brand-new calibration of the engine control parameters is needed. CFD-3D combustion simulation may be used as a costeffective tool to drive the experimental calibration process. This study reviews the building and experimental validation of a CFD 3D model, able to analyze this type of Dual Fuel concept applied to a current production light duty turbocharged Diesel engine, suitable for many different applications. A customized version of the KIVA-3V code is used, including a detailed treatment of chemical kinetics and soot formation mechanism.
