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
