论文已在中国上海举行的第27届CIMAC大会上发表。论文的版权归CIMAC所有。The newest version of the MTU Series4000 Gas Engines, the L64 presents the re-sults of consistent improvements in this highly modern gas engine family. The focus of the development was the in-crease in power of 130kW/cylinder and the increase in efficiency of 45% at the same time improving emis- sions. With its efficiency and power the L64 will beplaced in a crucial market position. The foreseeable power range will be up to 2.6 MW for the 20 cylinder version, while retaining an operating life of 64,000hrs. Furthermore through the higher cylinder power, a positive downsizing effect is achievable. To achieve the above mentioned customer benefits there were nu- merous technical measures necessary and this often in high detail. Here are just a few key points:· New combustion process· New cylinder heads for higher peak pressure· Reducing the crevices in combustion chamber· New steel piston design· New high pressure turbocharging· New Miller engine timing· Advanced ignition system for low NOx combustion· De throttling and optimizing all associated flow components Extensive testing has been taken to validatethese results, in addition several en-gines have been placed in the field running thousands of hours. The market launch will be in 2013/14 with all cylinder versions 8,12,16 and 20V beginning with 50Hz followed later by 60Hz versions.
