The New MTU Type L64 of Series 4000 Gas Engines
The newest version of the MTU Series 4000 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 increase in power of 130kW/cylinder and the increase in efficiency of 45% at the same time improving emissions. With its efficiency and power the L64 will be placed 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 64,000 hrs. Furthermore through the higher cylinder power, a positive downsizing effect is achievable. To achieve the above mentioned customer benefits there were numerous 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 validate these 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.
