CiMaC CongRess | SHAnGHAI 2013 will also show the improvements in reliability and customer maintenance. Finally, it will also show the improvements in fuel efficiency and flexibility compared with the first-generation system, and the reasons behind these improvements, as exemplified in Wärtsilä’s portfolio of second-generation CR products. Variable valve mechanisms for optimum performance at all loads and increased flexibility under all conditions have become the standard solution for most engines, the customer benefits being obvious. However, today’s 2013 systems are somewhat different than the systems in the late 90s, when Wärtsilä first introduced them for large medium-speed engines. Embedded automation is an enabler for most technologies being used on products in a reliable and repeatable way. Wärtsilä has continued the development of its UNIC system with increased functionalities, while maintaining high safety and offering a better user interface. The paper will describe the benefits of having one system. Aftertreatment systems integrated on engines offer a means of reaching the increasingly challenging emission limits with high efficiency. The paper will include Wärtsilä’s experience and the customer benefits with such systems. The paper will finally include an overview of the new diesel products in the Wärtsilä portfolio where the mentioned technologies are utilised. Examples include a new small bore engine / a locomotive adaption of the Wärtsilä 20 / the industrialised two-stage turbocharged Wärtsilä 32 / field experience with the new Wärtsilä 32 featuring the new generation of common rail / the Wärtsilä 46 and others. MAN Diesel & Turbo product portfolio of diesel engines adapted to actual challenges Detlef Kurth, MAn Diesel & Turbo, Germany Sonja Adorf, MAn Diesel & Turbo SE, Germany Armin Grabmaier, MAn Diesel & Turbo SE, Germany Ludwig Gruensteudel, MAn Diesel & Turbo SE, Germany Stefan Kolb, MAn Diesel & Turbo SE, Germany Bernhard Offinger, MAn Diesel & Turbo SE, Germany The product portfolio of diesel engines by MAN Diesel &Turbo contains several diesel engines adapted to special market segments. There are several challenges driving the actual development of diesel engines. Most important are the rules and regulations regarding emissions, the trend of global economics and the significance of new markets like offshore exploration. Especially the diesel engines have to include new technologies in order to manage the trade-off between emissions and specific fuel oil consumption. This paper shows diesel engines with consequent design for a special market segment. Some new technologies introduced into the market some years ago have now passed a reasonable operation time. Hence it is time to analyse the field issues in order to evaluate the technology readiness. The study of problems in diesel engine operation is also a method to show the need of new technologies due to the change of mixtures of heavy fuel or the like. The market specific design is shown for the 28/33D engine, which is developed for the high-speed ferry market and the navy market. The 32/44K engine is an example for an optimised design for auxiliary gensets. The well-known 32/40CD is taken as an example for the need of new design adapted to new heavy fuel oil mixtures. Long-term experience with common rail technology is available for the 32/44 CR engine type. This engine is also an example for the potential to increase output or adapt new technologies. A damage of an injection part will be used as example to show pitfalls with long term validation for optimised parts. This engine is also an example for the adaption of new technologies like variable valve timing, common rail and two-stage turbocharging. Tuesday May 14th / 10:30 – 12:00 Room B Product Development Gas and Dual-Fuel Engines – new Gas Engine Types 2 MACH II-SI achieved higher thermal efficiency Hajime Suzuki, Mitsubishi Heavy Industries,Ltd, Japan Hiroshi Yoshizumi, Mitsubishi Heavy Industries,Ltd, Japan Michiyasu Ishida, Mitsubishi Heavy Industries,Ltd, Japan Shoji namekawa, Mitsubishi Heavy Industries,Ltd, Japan Shinnosuke Osafune, Mitsubishi Heavy Industries,Ltd, Japan Against a background of recent energy issues, demand of more efficient operation for power plants typified by the distribution of power plants involving the smart-grid concept are growing, while the use of shale gas as well as the extension of gas pipelines has been steadily progressing. Therefore, the gas engine market is definitely expected to grow at a steady pace. Gas engine power generation has a lot of characteristics: High environmental performance, high thermal efficiency, high quickstart and load following capability, high exhaust heat recovery. The KU30GSI gas engine has already realised the superior utilisation for exhaust energy and cooling energy, like steam, hot and cold water, and, thus, fulfil the higher efficiency as a cogeneration unit. In addition, its excellent performance for rapid starting potential makes it possible to apply to the back up for renewable energy powers. Mitsubishi Heavy Industries, Ltd (MHI) has already received orders of over 30 sets of the KU30GSI, and requests from many clients regarding the consideration of the introduction of the KU30GSI with the favourable feedback of its reliability based on the abundant track record. To cater for the recent demand of the customer, focusing on the power generation, MHI has completed the work for its efficiency increase, and achieved an excellent efficiency of 48.8% (ISO3046). The thermal efficiency improvement is an important item, which not only lowers the operation cost, but also leads to environmental load reduction and energy saving. Enhancement for Miller cycle, high efficiency turbocharger METMB and optimisation for combustion chamber aiming fast burn concept contribute to fulfil this efficiency improvement, which was thoroughly evaluated through the test engine verification. Three engines applied to this high efficiency specification were already delivered and have been in successful operation. This paper describes the features and technologies, including the latest development for this efficiency improvement, of the KU30GSI gas engine as well as the operation result on actual site. The new MTU type L64 of series 4000 gas engines Udo Sander, MTU Friedrichshafen GmbH, Germany Stephan Menzel, MTU Friedrichshafen GmbH, Germany Markus Raindl, MTU Friedrichshafen GmbH, Germany The newest version of the MTU series 4000 gas engines, the L64 presents the results of consistent improvements in this highly modern gas engine family. The focus of the development was the increase in power of 130 kW/cylinder and the increase in efficiency of 45% while reducing 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 hours. 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, 26 sPeCiaL Schiff&Hafen | Ship&Offshore | May 2013
