Future C&I engines
Series 1000 to 1600 in the 100kW to 730kW power range will be available from 2014 for construction and industrial machines. Exhaust gas recirculation, SCR units and diesel particulate filters mean that the series 1000 to 1500 engines are compliant with the US Environmental Protection Agency‘s `Tier 4 final´ emissions regulations. MTU’s development goal, however, is to fulfill Tier 4f without diesel particulate filters. For compliance with EPA Tier 4f-limits, the series 1600 engines will be equipped with in-engine exhaust gas recirculation technology and a diesel oxidation catalyzer. MTU’s development goal, however, is to fulfill Tier 4f without any aftertreatment equipment.
The new generation of Series 2000 C&I for Tier 4i covers a power range from 561 to 1,163 kW (752 to 1,560 bhp) and fulfills the emissions limits using only in-engine technology and no exhaust gas aftertreatment. Despite the significant reduction in emissions limits, the new engines use up to 10 % less fuel than their predecessors. A larger performance map, higher torque by lower engine speed due to the two stage turbosystem and the new common rail fuel injection system give the engine a better load acceptance. The 12- and 16-cylinder versions of the engines will be introduced onto the market in stages from mid-2011. From 2015, the Series 2000 will be available in a Tier 4f version. Even for this emission stage MTU plans to fulfill the emission limits using only in-engine technology.
New engines for oil & gas
The new generation of MTU Series 2000 and 4000 engines for the growth market oil and gas industry with EPA Tier 4 interim, the current US emissions standard. They do so without the need for exhaust gas aftertreatment, and with even lower fuel consumption than before. They also provide the basis for Tognum’s current development work on engine compliance with Tier 4 final, the even tighter emissions regulations to apply in the US from 2015. Here as well, Tognum is looking for an in-engine solution.
Forward-looking drive solutions for the rail industry
The complete portfolio of environmentally-friendly rail engines that will meet the EU Stage III B emission regulations will include the newly developed 12 cylinder Series 1600 engines for locomotives and railcars, the new generation of Series 4000 engines for locomotives and underfloor Powerpack drive units for railcars. The new generation of Series 4000 engines has been certified by the German Federal Motor Transport Authority for future EU Stage III B emission standards. Series 4000 engines incorporate exhaust gas recirculation and diesel particulate filters and already meet the EU Stage III B emissions regulations that are due to come into force as from 2012. They cover a power range from 1,000 to 2,700 kilowatts and will be launched on the market in stages as 8, 12, 16 and 20–cylinder versions as from 2012.
For underfloor Powerpack drive units, MTU will also be offering a solution that meets EU Stage III B emission standards as from 2012. The traditional Powerpack with the 6H 1800 engine complies with these emission levels by incorporating an SCR catalytic converter and covers a power range from 315 to 390 kilowatts. A Powerpack will be launched on the market with the future Series 1600 MTU rail engine. As from 2013, it is to be available with power outputs of 565, 625 and 660 kilowatts.
Upgrade for Series 1163 marine engines
Tognum subsidiary MTU Friedrichshafen GmbH will upgrade its Series 1163 marine engines for the IMO 2 and IMO 3 emissions regulations. The 2-stage turbocharging technology will also be retained, but with its efficiency optimized even further. New features in this series are the common rail injection system (1,800bar injection pressure), the ADEC electronic engine management system and a new combustion process. Compliance with the IMO 2 emissions regulations due to come into force from 2011, will even be achieved using only in-engine technology and without exhaust aftertreatment. The new engines will also meet the latest requirements of the classification societies covering, for example, low noise emissions, high shock resistance and shielding against electromagnetic influences.
IMO 3 emissions regulations, which will be introduced in 2016, will most probably be met by using an SCR system to reduce nitrogen oxide emissions. This ensures that in future, the engines will be able to continue to operate in Emission Control Areas (ECAs). The three cylinder configurations (12V, 16V and 20V) in the 1163 engine family cover a performance range from 4,440 to 7,400kW at 1,300 rpm.
