柴油机的未来

阐明了柴油机未来发展中应重点解决的两大问题,即控制排放和提高热效率;对柴油机排放法规的动向进行了分析,对柴油机可能达到的排放水平进行了研究,重点论述了柴油机排气后处理技术;对进一步提高柴油机热效率的可能性进行了分析,指出其热效率可以达到与燃料电池相当的水平。

Future Prospects of Diesel Engine

This paper illustrates two key problems that should be ravelled out in the future development of diesel engine,i.e.exhaust emissions control and heat efficiency increase.Pulse of emissions regulations for diesel engines is analysed.The study is carried out on the emissions level that can be reached up by diesel engine.Exhaust after treatment technology of diesel engine is described with emphasis.Possibility of further increase in heat efficiency of diesel engine is analysed.It is pointed out that heat efficiency of diesel engine can reach a corresponding level to that of fuel cell.
