现代船舶柴油机节能减排技术研究

随着全球环境的日益恶化和人们环保意识的不断增强,船舶柴油机废气排放已经引起人们的重视。通过研究柴油机燃烧特点、电喷柴油机结构,优化其结构达到节能减排目的;研究进气对柴油机燃烧特性的影响,采取优化措施,并通过实验研究柴油机无氮燃烧(O2&CO2)可行性;研究现代先进燃烧技术特点,探讨其船用柴油机上应用前景;最后阐述柴油机NOx后处理技术研究现状。通过机前、机内、机后各项技术的综合运用,是柴油机节能减排的未来研究发展方向。

RESEARCH ON CONSERVATION AND EMISSION REDUCTION TECHNOLOGY OF MARINE DIESEL ENGINE

Along with the increasing deterioration of the global environment and improvement of environmental protection consciousness，the ship diesel engine exhaust emission has aroused people's attention． Through the research on diesel engine combustion characteristics and EFI engine structure，the structure was optimized to achieve energy conservation and emissions reduction; optimization measures were took to study the influence of the intake on diesel engine combustion characteristics; the feasibility of diesel engine No-Nitrogen( O2 ＆CO2 ) combustion was discussed through experimental study; modern advanced combustion technology characteristic was studied and its application was prospect on Marine diesel engine; finally，the NOx processing technology after the diesel engine was stated． The integrate use of technologies before，inside or after diesel engine， would be the future research direction for energy conservation and emissions reduction．
