Comparative analysis between natural gas/diesel (dual fuel) and pure diesel on the marine diesel engine

Abstract


The serious environmental pollution and the energy crisis all over the world have caused the development of lower pollution and lower energy consumption marine diesel engine to become a major research goal. In order to obtain the performance and emission of marine diesel engine on natural gas/diesel, a comparative analysis was carried out between the pure diesel mode and natural gas/diesel (dual fuel) mode at turbulence intensity, combustion process, rate of heat release and emissions. The performance of different fuel modes was studied through numerical analysis and experiment. The results showed that marine diesel engine, in natural gas/diesel mode, can get a lower turbulent kinetic energy, temperature reduction of about 400K, ignition advance, soot emission reduction by 75%, reduction of CO2 emission by 35% and NOx emission reduction by 80%.
