| Abstract:Based on the papers of the 29th CIMAC congress, the development tendency of combustion technology for marine medium and high speed engines is analyzed. It is pointed out that with the focus on energy saving and emission reduction, most papers focus on the combustion optimization of gas engines and dual fuel engines, and the application of low-carbon fuels. Research shows that combustion optimization can help to realize high reliability of gas and dual fuel engines, and emission reduction and high efficiency as well. With regard to fundamental research, the intelligent technology is applied to the combustion CFD process, in which the CFD simulation efficiency is enhanced substantially. The thermal load distribution principle can be analyzed accurately by introducing advanced measurements, such as tran-sient temperature transducers, and connected with the combustion process. Most of the research on the combustion technology in gas and dual fuel engines were made by Japanese or Korean companies while the European and American companies pay more attention to the fundamental experiments and application in marine engines of low-carbon fuels, such as bio-fuels, and the intelligent technology. |
