The D2862 is a fixed point in the agricultural business and with many hundreds
sold, is tried and trusted in operation all over the world: the most powerful field
chopper in the world today, the BigX 1100 from Krone, uses this efficient and
powerful MAN twelve-cylinder engine. MAN's D2862 V12 engine was also
decisive in the Claas Jaguar 980 field chopper being honoured with the
"Machine of the Year” award. The V12 engine is designed to be compact and
deliver high performance, outputting 793 kW (1,078 hp) at a weight of 1,820 kg
with the most economical fuel consumption.
Ideal basis for Tier 4 final
In order to comply with various emission standards around the world for the
power-output class over 560 kW, the future MAN D2862 will have a customerfriendly modular concept for exhaust-gas aftertreatment. Due to this modular
structure, the engines comply with EPA (Environmental Protection Agency) Tier 3
to Tier 4 final from 2015 on. What is modular here is the exhaust-gas
aftertreatment system - the basic engine remains the same. Benefitting the
machine manufacturers, the interfaces are identical while the engines themselves
are technically state-of-the-art and are especially configured to meet market
requirements. Thanks to the perfect interaction between components, raw
emissions within the engine itself are kept very low. "The current D2862
represents cutting-edge technology and is thus the outstanding basis for the Tier
4 final development. Using this almost unchanged basic engine, we are able to
achieve emission targets with the SCR system as a mounted solution. This
enables different engine applications for differing emission requirements to be
realised more straightforwardly. Moreover, the system is impervious to sulphur in

the fuel," says Otto Schnitzer, Vice President Engineering External Engines at
MAN Truck & Bus.
Tailor-made exhaust technology thanks to modular construction
MAN covers the entire output range from 110 kW to 882 kW (150 hp to 1,200
hp) with various key technologies. Amongst these are common-rail systems,
cooled exhaust-gas recirculation, dynamic turbocharger systems depending on
output class, SCR (selective catalytic reduction) technology and optional diesel
particulate filters (DPF). Their modular configuration permits operation in
accordance with the exhaust-gas standards and power requirements demanded
by the market. Machine manufacturers benefit in that they have to design their
equipment for operation in different markets - with identical interfaces - only
once.
Technology transfer through many years' experience
MAN has already been employing the key technologies necessary for meeting
the stringent Tier 4 final standard in its commercial vehicles successfully for
many years. The more than one hundred thousand engines installed in the
trucks and buses sold by the company every year offer synergies for technology
transfer. SCR, for example, has been standard in trucks since 2005. At its
Engine Competence Center in Nuremberg, MAN develops, designs,
manufactures and sells gas and diesel engines with outputs ranging from 37 kW
to 1,324 kW (50 hp to 1,800 hp) for the most varied of applications. Of central
importance in the development of these engines have always been the
customers' requirements with regard to the economy, power density and
reliability of the drives. The efficient engines from MAN Truck & Bus are
distinguished for their optimal fuel consumption and the minimal servicing effort
they require. The commercial vehicles and engine manufacturer from Munich
has rigorously followed the objective of complying with emission levels while
improving fuel consumption. Simultaneously, the company's engineers have
developed the engines demanded by the market, with ever-increasing dynamics
and power density.
MAN Truck & Bus range of diesel engines for industrial applications
MAN offers efficient diesel engines for agricultural technology, construction
machinery and mobile cranes, as well as for machines for materials handling
and environmental technology. Power outputs range from 110 kW to 882 kW
(150 hp to 1,200 hp) in numerous power gradings with a high torque increase
and a flat torque curve at low engine speeds. The technology company thus
offers the right design for every drive train. At the same time, a modular engine

concept is available for the four- and six-cylinder in-line engines as well as for
the V8 and V12 engines. Its use of different key technologies enables
compliance with exhaust-gas standards around the world by means of a single
engine design. All MAN engines are outstanding for their unbeatable reliability
in light-, medium- and heavy-duty operation. Their significant advantage lies in
their dynamic delivery of power at extremely economical consumption.
