The Prospective Analysis of Marine Dual Fuel Engine Application Based on Emission and Energy Efficiency

The new regulations on emissions and energy efficiency in the amendment to MARPOL Annex VI will become effective on January 1, 2013. The old-type marine main engine is difficult to come up to the new standard. Determining how to reduce the NOx, CO2 emissions and improve energy efficiency of ships draws a lot attention. The adaptability of marine dual fuel engine on the new regulations, EEDI and EEOI was studied, and the prospect of dual fuel engine is analyzed in this paper. To some extent, it has guiding meaning in the development of the marine main engine.
