Optimization of the Performance of Marine Diesel Engines to Minimize the Formation of SO _x Emissions

Abstract

Optimization procedures are required to minimize the amount of fuel consumption and exhaust emissions from marine engines. This study discusses the procedures to optimize the performance of any marine engine implemented in a 0D/1D numerical model in order to achieve lower values of exhaust emissions. From that point, an extension of previous simulation researches is presented to calculate the amount of SO _x emissions from two marine diesel engines along their load diagrams based on the percentage of sulfur in the marine fuel used. The variations of SO _x emissions are computed in g/kW·h and in parts per million (ppm) as functions of the optimized parameters: brake specific fuel consumption and the amount of air-fuel ratio respectively. Then, a surrogate model-based response surface methodology is used to generate polynomial equations to estimate the amount of SO _x emissions as functions of engine speed and load. These developed non-dimensional equations can be further used directly to assess the value of SO _x emissions for different percentages of sulfur of the selected or similar engines to be used in different marine applications.
