It's all
about taking the burden off the customer.
There's a new EPA mandate for 2010 that changes
the emission requirements for vehicles and you
will have two choices. Advanced EGR (exhaust gas
recirculation) and SCR (selective catalytic
reduction). International® stands behind
advanced EGR. Navistar®, our parent company,
looked ahead and has been developing this
technology since 2004. And although it wasn't
the easy route, we have always believed that an
in-cylinder solution was the right option to
develop because it requires our customers to do
nothing to comply with the new regulations. And
now we feel stronger about our choice.
The
new EPA mandates.
In 2010, the EPA is requiring new vehicles to
achieve a new diesel exhaust emissions
regulations limit, which is .2 NOx (g/hp-hr)
down from 1.2 in 2007. This was a difficult task
to achieve and we took a different path than the
rest of the OEMs by choosing an advanced EGR
solution.
Advanced EGR makes sense.
Next year you'll have two choices when you
purchase a vehicle: a vehicle that reduces
emissions in the engine cylinder (advanced EGR),
and a vehicle that reduces emissions by adding a
second fuel (urea) through an after-treatment
system (SCR). With the advanced EGR solution,
operating and maintenance requirements don’t
change for your drivers or mechanics. Compare
this to the SCR solution, where changes include
significant add-on after-treatment equipment,
additional attention from your drivers and new
maintenance and servicing requirements for your
technicians. With SCR, the burden on your clear,
and that’s why we believe advanced EGR just
makes sense.
It's built in to every MaxxForce Engines
EGR (Exhaust Gas
Recirculation) is an emissions reduction
technique used in most gasoline and diesel
engines. EGR works by re-circulating a portion
of an engine's exhaust back to the engine
cylinders and burning off excess pollutants.
When temperatures in the combustion chamber get
too hot, oxides of nitrogen (NOx) form. When
these nitrous oxides combine with hydrocarbons,
they produce the ugly haze we call smog. EGR
re-circulates this exhaust into the intake
stream. Since the exhaust gases have already
combusted, they don’t burn again. These gases
displace some of the normal intake, slowing and
cooling the combustions process, which reduces
NOx formation.
The challenge for 2010 is to precisely control
the flow of re-circulated exhaust. MaxxForce
advanced EGR engines have increased injections
pressure, improved combustion and refined
calibrations with that goal in mind. The result
is an engine that treats NOx in-cylinder, and
therefore requires no extra effort from our
customers.
Advanced EGR means less hassle
Navistar believes that there
is a better way. That's why we're introducing
our advanced EGR technology, built in every
MaxxForce™ Engine. Why advanced EGR? Plain and
simple. It only requires one fuel: diesel. So
it's business as usual for the operator and
maintainer.
The Advantages: *
No second fuel to worry about
* No new hardware to add
* No new training to operate and maintain
* No new Urea storage requirements to learn
* No Additional weight due to after-treatment
equipment
* No need to worry about the impact of extreme
fluid temperatures
