- Winners in "Environmental Excellence" category
- Readers vote for new generation of MTU Series 4000 without exhaust gas aftertreatment
- Key technologies create ideal drive solution for mining industry
Friedrichshafen, 30 January 2012. The readers of "Mining
Magazine" have honored Tognum subsidiary MTU Friedrichshafen
with the "Mining Magazine Award" in the category
"Environmental Excellence". The drive and propulsion
specialist received the award for its new Series 4000 engine
which meets Tier 4 final emissions regulations without using
exhaust gas aftertreatment systems. The mining industry makes
the award in recognition of outstanding new technologies,
machines and equipment in its sector. Readers of the trade
publication were asked to select their favorite from three
finalists in each of eleven categories with this year's award
including nominations for projects in the new "Environmental
Excellence" category for the first time. Competing with MTU
in the top trio were an Australian mine with a recycling
program for for its spoil tip and a Bolivian mine with a
59-meter high dust mitigation dome designed to reduce the
effects of dust on the environment. Readers of the trade
journal voted the MTU Series 4000 into top spot.
"During development of the new Series 4000 we took account of
machine manufacturers' demands as well as listening to
feedback from our end-users," explained Tognum CTO Dr. Ulrich
Dohle. "The end result was an engine which ideally matches
the needs of the mining industry." For example, despite
tighter regulations, Series 4000 engines meet the relevant
emissions targets with in-engine technology only and they do
that on up to 5 % less fuel than Tier 2 engines.
In its new 4000 units, MTU has put together a technology
package combining high-pressure injection, controlled
two-stage turbocharging and exhaust gas recirculation. The
key to its success lies in the perfect integration of all
these technologies. Because field trials under actual working
conditions provide indicators on where engines need further
optimization, MTU tested new technologies involving exhaust
gas recirculation and high cylinder pressures on prototypes
at a very early stage. From 2015, new generation Series 4000
engines will be going into operation in heavy mine vehicles,
wheel loaders and excavators with 8, 12, 16 and 20-cylinder
units covering the 800 kW to 3,000 kW power range.
