The joint venture started operations in
January 2010 with the name Bosch
Emission Systems GmbH & Co. KG and
is headquartered in Stuttgart, Germany.
The objective of the joint venture is to
use the core exhaust aftertreatment
competencies of the three companies
involved to offer complete aftertreatment
systems for construction and agricultural
machinery, as well as for commercial
vehicles with stricter emissions regulations from 2011 onward.
Series production will likely start in
the third quarter of 2010, the companies said.

Eminox
Eminox’s SCRT system combines continuously regenerating trap (CRT) technology with SCR. The SCRT system is
designed to remove over 90% of particulate matter, hydrocarbons and carbon
monoxide, plus 65 to 80% of NOx.
As concerns mount about the levels of
PM and NO2 present in Europe’s air, the
Eminox SCRT system is increasingly
being used to help cities across Europe
meet the tougher limits set by Europe’s
Ambient Air Quality Directive.
A cutaway of Elimnox’s SCRT system,
which combines continuously regenerating trap technology with selective
catalytic reduction.
Eminox has worked with urban governments and bus operators in Paris,
France; London, England; and Flanders,
Belgium, to meet local air quality requirements by retrofitting its emissions control
systems on city bus fleets.
The company’s SCRT was chosen
for one of Europe’s largest combined
PM and NO2 retrofit programs, which is
now nearing completion. More than
300 Eminox SCRT systems were supplied for the program.

Emitec GmbH
Emitec has introduced a new version
of its SCR system with the development
of the SCRadvanced (SCRa). The SCRa
capitalizes on the potential offered by
metal catalyst substrates and uses a tur-bulence-generating structure for maximum performance with minimum installation space. An internal catalyst is used
for mixing and flow equalization, and a
variety of flexible designs are offered.
The SCRa system is a multistage
process that consists of a close-coupled
module, including an oxidation catalyst, urea injection and an SCR catalyst. The ring-shaped oxidation catalyst
deflects exhaust gas and flows it back
through an inner tube.
Urea is injected into the deflection
chamber to produce an optimum mixture
