Clean power for high speed trains
Mike Ferris, CEO of MTU-UK Ltd, explains more about the new MTU Series 1600 PowerPack.
Equipped with MTU diesel engines, British DMU railcars, locomotives and high speed trains have been able to complete millions of running hours with an impressive availability.
With its new PowerPack featuring the rail version of the Series 1600 engine, MTU presents the latest evolution in the successful development of compact traction solutions.
Flexible, economical, clean
Available from 2013, the Series 1600 PowerPack is an innovative drive system that combines all the individual system elements into a single fully-functional unit mounted on a supporting frame. The drive solutions will be introduced into the market with 12V1600 engines and a power output between 565 and 700kW. MTU offers all three types of power transfer: clients will be able to choose between dieselelectric, diesel-hydraulic and diesel-mechanical versions of the PowerPack and therefore integrate them perfectly in their vehicle design.
MTU supplies all the elements of the drive system, so responsibility for the design and performance of the drive system as a whole stays in one place. Specially designed for underfloor installation, MTU PowerPacks are characterised by their flat design and, thanks to their modular structure, every unit can be individually configured.
They weigh less than comparable drive solutions and require fewer interfaces. Thanks to the latest emissions technologies, MTU rail engines are amongst the cleanest drive systems in the world. An electronic control system precisely adjusts the drive system to match the prevailing operating conditions – and ensures fuel-efficient operation by limiting the power produced to the amount actually needed by the traction system: a big plus for the environment, because less fuel means lower CO2 emissions.
In addition, the exhaust gases are cleaned via selective catalytic reduction so that emissions meet the stringent demands of EU Stage IIIB emissions regulations.
Traction solution for high-speed trains
MTU PowerPacks set the benchmark for what diesel drive systems must deliver in this demanding sector. The PowerPacks’ uncompromising operational availability ensures that railway operations run with absolute reliability, while their exceptional efficiency is a key factor in the economic success of train operators. Featuring excellent acceleration, low life-cycle costs and exceptionally low noise and vibration levels, the drive concept is tailor-made to meet rail operators’ demands for high performance, exceptional reliability, and efficient fuel consumption.
Selective Catalytic Reduction
The term Selective Catalytic Reduction (or SCR) is used to describe a chemical reaction in which harmful nitrogen oxides (NOx) in exhaust gas are converted into water (H2O) and nitrogen (N2). In combination with internal engine technologies, such as exhaust gas recirculation (EGR), extremely low nitrogen oxide emissions can be achieved with low fuel consumption. The added benefit of an SCR system is a reduction in particulate emissions of up to 60 percent. This frequently means that – depending on the emission standard applicable – the need for an additional diesel particulate filter (DPF) in the exhaust system can be eliminated.
MTU assists its customers in the design of the reducing agent supply system for the SCR system. For the underfloor rail PowerPack equipped with a 12V 1600 engine, MTU is developing a complete SCR system that, in addition to the catalytic converter and metering system, includes a reducing agent tank, heater and piping.
Mike Ferris has 30 years’ experience in the diesel engine industry, the last 22 years with MTU. In addition to rail, he has indepth operational knowledge of a number of industries including marine, oil & gas and power generation. In 2007 Mike Ferris was appointed CEO of MTU-UK Ltd and in 2011 accepted the additional role of Director of Network Management for Northern & Central Europe.
