mtu showcases future engines for agricultural machinery at Agritechnica

• EU Stage IV and US EPA Tier 4 final from 2014 without diesel particulate filters
• Fuel consumption up to five percent lower
• From 2014, power range from 100 to 730 kW

Friedrichshafen, 26 July 2011. At this year’s Agritechnica agricultural machinery exhibition, Tognum will be showcasing its mtu brand agricultural engines designed to meet EU Stage IV and US EPA Tier 4 final emissions regulations scheduled for introduction in 2014. The newly-developed Series 1000, 1100, 1300 and 1500 engines meet the upcoming emissions limits using SCR exhaust aftertreatment technology only and will need no diesel particulate filters. The units cover the sub-560 kW power range. From 2014, Series 1600 agricultural engines which need neither SCR systems nor diesel particulate filters will be introduced to extend the range to 730 kW. The agricultural machinery exhibition takes place from 15 to 19 November in Hanover.

„We are proud that, in the future, we will continue to be able to offer all our customers engines without diesel particulate filters for all agricultural applications. They are cleaner than ever before and they use even less fuel than the current engines,” said Peter Kneipp, Tognum Executive Board member with responsibility for the Business Unit Engines, highlighting the company’s technological expertise as well as its competitive edge.

From 2014, mtu will be introducing its new Series 1000, 1100, 1300 and 1500 engines with outputs ranging from 100 to 460 kW. These units have been specially developed for off-highway applications in the construction, industrial and agricultural sectors and are based on Daimler technology. They will utilize an SCR exhaust aftertreatment system to achieve compliance with the extremely stringent limits set by EU Stage IV and EPA Tier 4 final for nitrogen oxides and particulate emissions. However, the units do not need diesel particulate filters and therefore offer significant benefits in terms of installation space and weight. As early as 2010, mtu was one of the first engine manufacturers to present its entire family of sub-560 kW industrial engines designed to meet the emissions regulations scheduled for 2014. Compared with units designed for EU Stage IIIB or EPA Tier 4 interim, customers for the new engines will benefit from reductions of up to 5% in fuel consumption, an increase in service life of up to 20%, higher torque at lower engine speeds, greater engine brake power and fast, straightforward maintenance.

From 2014, the program will be extended to 730 kW with the introduction of Series 1600 engines. These off-highway units can be used in forage harvesters and other agricultural vehicles and machines with high power requirements. They meet EPA Tier 4 final specifications using in-engine technologies involving exhaust recirculation and diesel oxidation catalysts. mtu placed particular emphasis on optimizing the combustion process in order to minimize fuel consumption. Overall, customers will benefit from an integrated system with low conversion and operating costs.

mtu’s role as a reliable partner for its customers does not rest exclusively on its products but equally on its service program mtu ValueCare which is tailored individually to match the customer’s specifications no matter what the demands. The mtu ValueCare Service program, which includes the fast and reliable supply of high-quality, original brand spare parts, is operated by more than 1,200 Service Centers worldwide.
