heal.abstract	In recent years, the environmental pollution has become a major issue and efforts are being made to find a solution. In this respect, Dual fuel engines have been evolving in recent years with the aim of reducing pollutant emissions and meeting the demand of the upcoming emissions regulations. In this thesis was developed a combustion model in order to estimate the Heat Release Rate and the In-Cylinder Pressure of a Dual-Fuel Internal Combustion Marine Engine fueled by Methanol in combination with Pilot Injection of Diesel. Based on data from papers and experiments taken from bibliography, firstly an Ignition Delay model was investigated to predict the Start of Combustion. Subsequently, in order to estimate the Heat Release Rate, was selected a zero-dimensional and semi-empirical approach. Triple Wiebe functions were investigated, whose parameters were fitted using the experimental data. Furthermore, polynomial fit was applied in order to develop models for the Wiebe Parameters. The Heat Release Rate Model mentioned above was validated through data from bibliography that wasn’t used in the model development, in order to verify its prediction capability. Ultimately, the in-cylinder Pressure was predicted using the Heat Release Rate Model and the first law of Thermodynamics and was validated from experimental data	en
