Friedrichshafen/Berlin – From19th to 22nd September 2006, MTU Friedrichshafen GmbH will be showing off its internationally successful underfloor rail PowerPack with 6H 1800 at the world’s largest rail exhibition InnoTrans in Berlin. Currently the most powerful in the range, the 390 kW unit on exhibition incorporates the new EcoLife gearbox from ZF Friedrichshafen which is particularly competitive.
The MTU PowerPack combines all the individual drive sub-assemblies on a single raft to form a complete functional unit. Diesel-mechanical and diesel-hydraulic units are coupled with a gearbox. Diesel-electric drives have a generator. The drive block is mounted on the raft together with all the necessary sub-assemblies including fuel, oil and air filters, exhaust silencer and the entire cooling system with hydrostatic pump, motors and cooler fans. Also incorporated are assemblies which do not form part of the vehicle drive unit such as a compressor for the braking system, one for the aircon cooling circuit and a generator for train electricity.
The extremely flat design of the units, which can be mounted in any of three different raft versions, makes MTU PowerPacks the ideal underfloor drives for railcars and push-pull trains. Their compact, modular construction reduces the overall weight of the drive system and allows straightforward removal and refitting for maintenance. System interfaces have been kept to a minimum to facilitate standardized solutions and produce clear cost savings overall. Another benefit for customers is that MTU is responsible for the entire system.
MTU’s rail PowerPacks are compact underfloor drive units incorporating engine, cooling system, gearbox, generator and other sub-assemblies. A diesel particulate filter can be integrated in the silencer.
MTU PowerPacks available with soot particle filter as an option
As an option, MTU PowerPacks are also available with a soot particle filter which is integrated in place of the silencer and performs silencer functions. The particulate filter, which was co-developed by MTU, works on the wall-flow principle. These soot particles, predominantly consisting of carbon, react at temperatures above 350°C with residual oxygen in the exhaust and the catalyst to form carbon dioxide. The continuous regeneration process involved means that the filter can operate for several thousand hours before it needs cleaning.
Even without diesel particulate filter MTU PowerPacks already comply with the EU Stage 3A emission limits which come into efffect in 2009. With the filter, they also meet Stage 3B specifications for soot particle emissions due to come in from 2012.
The untreated exhaust gases flow from the PowerPack engine into the MTU diesel particulate filter. The catalytically-coated filter, which was co-developed by MTU, removes more than 95% of the diesel particles from the exhaust.
315, 335, 360 or 390 kW of compact power
MTU Powerpacks with engine type 6H 1800 have now been on the market for three years and are gradually replacing their highly successful predecessor, the 6R 183. With around 3,000 of the older-generation 275 kW and 315 kW underfloor units sold, the 6R 183 had set the pace in the railcar marketplace since 1998. The latest and more powerful generation is MTU’s response to the changing demands of rail customers who now run longer trains at higher speeds with shorter stop/go duty cycles and therefore need even greater performance from their compact underfloor units.
The new and more powerful engines are not only intended for new vehicles but also for repowering older push-pull trains. “That is why we took great care to ensure that the latest PowerPacks will fit the same footprint as their predecessors and that the interfaces match”, explained Dr Gerd-Michael Wolters, Executive Vice President, Engineering & Operations at MTU Friedrichshafen.
In line with the single-source drive concept, MTU also supplies the matching electronics. The PowerLine automation system takes care of control, regulation and monitoring processes for the entire drive plant. This modular electronics system guarantees optimum adaption of the drive to the multi-faceted operating conditions which prevail in rail applications. PowerLine facilitates straightforward integration in both new and existing vehicle control systems. Its integrated safety system enables PowerLine to adapt engine performance automatically and to stop the engine in an emergency. Enhanced (remote) diagnostics functions and intelligent CAN-Bus technology are two of the system’s other benefits.

PowerPack Sales Hit: Customers order over 400 underfloor drive units from MTU Friedrichshafen in current year
Day in and day out, another MTU PowerPack comes onto the market in the rail sector; 2006 alone will see more than 400 of these drive units. “We are particularly proud of the order from the Korean vehicle manufacturer Rotem”, said Rainer Breidenbach, MTU Executive Vice President, Sales & Marketing. “On the one hand, this is our first success in gaining an Asian manufacturer as a customer and on the other hand, the size of the order, for 120 PowerPacks with an option for a further 60, is extremely impressive”, explained Mr Breidenbach. “And in addition, the PowerPacks will be driving diesel railcars for Irish Rail which is yet another new success story for us.”
- Plug & Play: Simple installation and easy operation
- Sophisticated color visualization
- Optimum coordination between engine and propulsion system
MTU will present its newly developed Bluevision automation system to the North American market. These comfort electronics for ships with Series 2000 and 4000 engines offer an optimally coordinated propulsion unit and remote control system for various propulsion systems. There are separate Bluevision versions for classified and non-classified vessels. Electronics for engines and propulsion systems developed and manufactured in-house are an MTU hallmark.
Plug & Play: Simple installation and easy operation
Simple installation and easy operation are important shipbuilding requirements placed on modern electronic systems. The comprehensive Bluevision system plug & play package can thus by all means be described as an all-inclusive, worry-free package. All the hardware components in the system are easily installed. The vessel cables, required for the flow of data between the engine room and the helms, are easily installed – prefabricated cables with plugs simplify connections. The electricians are spared complicated terminal diagrams. This guarantees rapid commissioning.
Sophisticated color visualization
Ships’ captains today want appealing and clear displays with color graphics that they can get along with immediately in all situations. High-resolution, modern flat monitors and trackball operation guarantee this in all sailing and operating situations and thus offer additional safety. Another characteristic of Bluevision are the new on-screen features, which leave no questions unanswered for the user: the realistic engine technology display, the directly accessible engine documentation and the option of configuring the so-called trend of freely selectable measuring points, enable the user and those responsible for engineering on board to be in complete control. If desired, a second language can be displayed on the monitor in addition to English.
Optimum coordination between engine and propulsion system
In addition, Bluevision offers an optimally coordinated control center and remote control system for propulsion systems with fixed pitch propellers, adjustable pitch propellers, Voith-Schneider or water jet systems for ships with one to four shaft drive systems. The Bluevision monitoring system logic starts in the engine room and can be extended for four helms (for unclassified vessels) or for six helms for classified vessels. Fast, redundant CAN databus connections, control stands in the engine room (LOP) and the option of integrating measuring points in the so-called general ship area (for example for the monitoring of the bilges and fuel tanks) into the system are additional distinguishing features of Bluevision.
