EMCON TechnologiesSM is a leader in the global exhaust
emission control technology industry. The company serves
worldwide passenger car, commercial vehicle and engine
manufacturers. This $3 billion business has operations in 19
countries with 7,500 employees and several long-term joint
venture relationships.

EMCON Technologies was spun off from ArvinMeritor in 2007.
The company was a pioneer in the emissions control business,
introducing the first catalytic converters for passenger cars
in 1974 and was the first to introduce stainless steel and
subsequently titanium exhaust systems. As one of the founders
of the exhaust after-treatment business, the company has
long been known for its ability to bring products with greater
efficiency, quality and performance for original equipment
manufacturers of engines and vehicles, to end-users.
The company has spent more than three decades developing
effective emissions control products. EMCON Technologies has
extensive experience as a systems integrator offering numerous
applications to customers worldwide. EMCON Technologies is a
major supplier of three-way catalytic converters, diesel oxidation
catalysts and Diesel Particulate Filters (DPF) for passenger cars.
Worldwide customers include most of the world's major
car manufacturers.
Since 2005, EMCON Technologies has become a leading
independent supplier of exhaust aftertreatment to the world's
truck and commercial vehicle engine manufacturers.

The emission control technologies
offered for the Commercial Vehicle and
Non-Road markets are designed for a
diverse range of applications including
on- and off-highway diesel engines,
urban-use commercial vehicles, and
non-road machines and engines for a
wide range of duty cycles.
|
|
The commercial vehicle emission
business group has introduced products
to meet Euro 4 and Euro 5, EEV
and EPA2002 and EPA2007 heavy-,
medium- and light-duty truck emissions
standards. EMCON's commercial vehicle
customers include Iveco, DAF/Paccar,
DaimlerChrysler, Caterpillar and Volvo. The company was
one of the first to introduce Selective
Catalytic Reduction (SCR) and large
Diesel Particulate Filters (DPF) to the
on-highway market. Products currently
in development will satisfy future
applications to meet future emission
standards such as Euro 6, EPA2010,
Japan 09 and Tier 4 and Stage 3b nonroad
standards. These products include
combined SCR/DPF systems which will
provide extremely high reductions in
NOx and particulate emissions.
|
|
Across the globe, environmental
standards for emissions of particulate
matter and oxides of nitrogen from
all diesel engines are becoming
increasingly stringent. New products
are being developed for the emerging
markets in Asia and for new applications
in the non-road market.
EMCON Technologies has advanced
emissions research and design expertise,
proven manufacturing capability and
extensive experience as a systems
integrator to deliver solutions that can
be tailored to meet unique needs and
applications across the world.

The TR is an independent fuel burner designed to provide rapid
regeneration of a DPF on demand. It is currently the only such
device on the market which is capable of ensuring complete
regeneration of a filter at any time and at point in the drive
cycle. The TR is in production for EPA2007 applications and
will be applied on U.S. 2010 and Tier 4/Stage 3b compliant
vehicles and engines. It is ideal for application where exhaust
temperatures may be too low to guarantee continuous
regeneration of the filter.
The TR is capable of initiating, maintaining and controlling
regeneration at engine low-load and low-temperature
operating conditions, making it an especially attractive and
effective solution for stop-and-go vehicle and low exhaust
temperature applications. This feature eliminates the possibility
of having to initiate a manual regeneration cycle, whereby the
truck is required to be stationary and idle for times generally
ranging between 20 and 60 minutes.
Multiple configurations allow packaging and design flexibility
for different applications. The intrinsic ability to regenerate on
demand and control the exhaust temperature at levels of 650
degrees C, allow the use of uncatalized filters which are free
from the significant cost and market fluctuations of precious
metals such as platinum.
The TR may also be used as a temperature control and
regeneration-assist module for SCR and LNT systems, where
a minimum temperature needs to be maintained in order for
effective NOx conversion. It is also offered with a dedicated
control unit that can also function in predictive modes.

The DPF is highly effective at removing
the carbonaceous solids, liquids and
other particulate emissions from diesel
exhaust. Typically a ceramic wall flow
filter is combined with a diesel oxidation
catalyst in a single unit. The catalyst
is able to remove hydrocarbons and
carbon monoxide and at the same time
provide virtually continuous removal of
trapped particulate matter from the filter.
Filtration efficiencies may be as high as
99%. As well as being a major supplier
to the passenger car market in Europe,
EMCON Technologies is a leading
supplier of the DPF product in the U.S.
and European on-highway market. In
the future, it is envisaged that nearly all
large diesel engines will require a DPF to
comply with regulations.

The Atomizer was developed as a
means to inject hydrocarbons (normally
diesel fuel) into an exhaust stream for
the purpose of generating exothermic
heat over a Diesel Oxidation Catalyst
(DOC) in order to actively regenerate a
DPF. The Atomizer is also developed to
enable operation of a Lean NOx Trap
by introducing a brief rich atmosphere
to reduce adsorbed nitrate. In addition,
it can also provide heat for LNT and a
rich atmosphere for desulfurization by
exothermic reaction of the fuel over a
DOC. The Atomizer can be used for a
combined DPF/LNT system.
The air-assisted system has a control
unit that assures accurate temperature
control and fast response. In the DPF
application, the software determines
the optimum time and interval for
regeneration.

SCR is a highly efficient means of
removing Nitrogen Oxide gases (NOx)
from the exhaust emissions of diesel
engines. It utilizes a reagent, 'AdBlue'
to convert NOx emissions, the major
contributor to smog, into water and
Nitrogen, a component of clean air.
AdBlue is injected at varying rates that
follow the concentration of NOx present
in the exhaust.
SCR is extensively and successfully
used on on-highway medium- and
heavy-duty truck applications in
Europe and for many years, has been
used to attain very low nitrogen oxide
emissions from stationary sources
around the world. SCR is an alternative
to conventional non-aftertreatment
emission reduction methods, providing
flexibility to tune the engine for higher
efficiency, thus improving engine
fuel economy. Developments in the
technology now permit conversion of
NOx emissions to exceed 90%.

DPF and SCR systems are being combined to meet the next
round of stringent emission regulations, such as U.S. 2010,
Euro 6 and Tier 4/Stage 3B, where extremely low NOx and PM
emission limits are mandated.
EMCON Technologies has pioneered the development of such
systems and introduced the first fully integrated SCR/DPF unit
to the European market in 2006. Development of this product
is continuing in order to satisfy demand for the forthcoming
regulations in Europe and America. Products are designed to
achieve compact packaging, minimum weight, high durability,
emissions and noise performance.
|
EMCON Technologies is continuing to provide advanced
solutions to meet the future needs of its customers. The
application of the burner system (TR) with SCR/DPF is seen as a
way to enhance the performance of the SCR at low temperature
and at the same time provide a reliable regeneration system
for the filter unit. A major benefit of the TR is that it is possible
to avoid the use of precious metals thus potentially saving
the high cost associated with platinum and other expensive
metals. Integration of the TR into SCR and DPF systems will be
especially beneficial in many non-road applications where the
duty cycle of the engine is highly variable.

|
EMCON Technologies has pioneered the development of combined DPF/SCR systems to meet the toughest emission
standards yet to come. Such a system has been successfully launched and has been in production since 2007.
