该论文已在赫尔辛基举行的第28届CIMAC大会上发表，论文的版权归CIMAC所有。In January 2013 CO2 emission regulation by IMO went into force and the Energy Efficiency Design Index (EEDI) was applied to indicate CO2 emission category of a ship. The value of EEDI is the result of several ship design selections, among them there is the selection of the engines: main and auxiliary. The EEDI is an index indicating the energy efficiency of vessels, therefore the EEDI becomes one of the important index of maritime diesel engines. In this view, YANMAR continues various researches and developments to achieve a substantial reduction of the fuel consumption for improving the value of EEDI. There are not many parameters influencing the fuel consumption, the most important are: the peak firing pressure, the air to fuel ratio, the Gas exchange work, the reduction of heat losses, the combustion process and the engine friction. In this paper YANMAR presents the result of a project based on the improving the gas exchange work, the combustion process.
