该论文已在赫尔辛基举行的第28届CIMAC世界大会上发表，论文的版权归CIMAC所有。 The latest incidents of the political destabilization will increase in all probability our efforts to get more independent of oil-base energy sources. In addition also the tightening of the worldwide exhaust gas regulations will act as a driving force towards gas and Dual fuel engine development. When the energy demand is increasing constantly worldwide the developing countries are decentralizing their electrical power supply by using in the large stationary power plants the gas engines. Due to geo-political or environmental reasons the use of alternative fuel is also necessity, sometimes for unlimited time. Therefore the optimum thermal efficiency of the engine has to be provided both with gaseous and liquefied fuels. When considering the marine propulsion system the alternative of LNG to HFO is under an extensive discussion right now. In the LNG vessels the 4-Stroke dual fuel engine has been successfully operating for multiple years and now the customers operating with other type of vessels – like for example cruise vessels have appointed their strong interest towards the use of dual fuel engines. Also with marine application the interim operation with LFO or HFO with unlimited time is often a strong demand and therefore considered as development area what comes to combustion control and engine convertibility. This article focuses on new 4-stroke large and medium bore dual fuel engine portfolio development for marine and stationary power plant solutions concentrating on the following topics: Engine reliability, transient operation capability, operational flexibility and the increase of thermal efficiency with liquefied and gaseous fuels.
