Advanced EGR

MaxxForce® Advanced EGR. The No-Hassle 2010 Solution.

Advanced EGR Lets Drivers Do What They Do Best.

At International®, our customers' best interests always come first. So when EPA emissions regulations tighten, it shouldn't be up to our customers to comply. It should be up to us. That's why we introduced MaxxForce® Advanced EGR technology as our 2010 emissions solution. It doesn't require drivers to install and maintain extra equipment. Or worry about where to find exotic fluids like urea. They just have to put the hammer down and head for their next destination. MaxxForce® Advanced EGR is one more way we put our customers Miles Ahead.

 

2010 Requirements

MaxxForce® Advanced EGR. The No-Hassle 2010 Solution.

For 2010, The EPA Gets Tough. So We Give You an Easy Choice.

Next year, the EPA requires diesel exhaust emissions to be reduced by 98%. Great for the environment. But it caught other engine manufacturers off guard. They fell back on technology called SCR that requires adding hevery after-treatment equipment which utilizes a hard-to-find fluid called urea. Taking the opposite approach, International® prefected its proprietary Advanced EGR system that requires no additional equipment, maintenance or driver training. For 2010, there's only one choice that makes sense: MaxxForce® Advanced EGR.

 

How Advanced EGR Works

How Advanced EGR Takes the Burden Off You.

MaxxForce® Advanced EGR reduces emissions inside the engine itself. It simply recirculates part of an engine's exhaust back to the cylinders, slowing and cooling the combustion process and burning off pollutants. International's Advanced EGR requires a combination of increased injection pressure, improved exhaust flow and refined calibrations - but the result is greatly reduced emissions without any extra effort on your part.

 

Advantages

Less Hassle. The Whole Reason Behind MaxxForce® Advanced EGR

Unlike other manufacturers, we chose to improve Advanced EGR because we put our customers first. MaxxForce® Advanced EGR technology doesn't require customers to do anything differently from what they do today. And less hassle is always good.

The advantages of Advanced EGR:

• No urea to purchase and store
• No urea storage tanks to install
• No added after-treatment components
• 200-300 pounds less weight (more payload)
• No additional training needed for drivers and technicians
• Stable trade-in value
• No truck disablement if urea runs out

 

2010 FAQ

MaxxForce® Advanced EGR. The No-Hassle 2010 Solution.

What choices are OEMs offering?

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 you is clear, and that's why we believe advanced EGR just makes sense.

Why is Navistar the only OEM offering an in-cylinder solution?

We pursued Advanced EGR because it was simply the right thing to do when we looked at it from a customer standpoint. Our customers don't need extra hassles or higher operating costs, and MaxxForce Advanced EGR is the only solution that avoids both. We developed a high-pressure fuel injection system years ago, knowing that this technology would allow us-and only us-to deliver a superior emissions solution.

How does MaxxForce Advanced EGR work?

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 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 combustion 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 injection 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.

What are the main differences between EGR and SCR?

MaxxForce Advanced EGR there are no extra fluids to buy, store or deal with.

• There is no new hardware to add.
• And there is no new training needed.
• SCR requires all of the above.

Will mounting be easy?

With the Navistar 2010 solution, there will be no additional hardware on the chassis and there will be minimal additional body builder chassis packaging requirements.

Will there be a payload penalty with MaxxForce Advanced EGR?

Because MaxxForce Advanced EGR handles emissions reduction inside the engine, there's no additional after-treatment equipment that adds significant weight to the chassis. This means customers will not have to reduce their payload. The competitive SCR 2010 solution adds 200-300 lbs. in additional hardware to a truck.

Will it affect engine reliability and durability?

While other OEMs have been working to re-engineer their engines to include SCR technology, International hasn't. In fact, the International 2010 emissions solution is based upon the technology solution we brought to market in 2007. This approach means your customers will not have to rely on unproven technology.

Will it be hard to maintain trucks with MaxxForce Advanced EGR?

Our solution does not require the use of urea and therefore requires no additional equipment to learn or new fluids to deal with. It will be just like operating the truck you drive today. For every hundred gallons of diesel fuel consumed, SCR systems will require 1 to 4 gallons of urea. These 15-gallon urea tanks will need to be filled periodically or the truck will become disabled.

Will SCR provide a lower operating cost?

SCR will not yield a lower operating cost; in fact, SCR will likely result in a higher operating cost when you consider the need to purchase urea. Purchasing urea in the United States today costs over $35 per gallon. Even in Europe (where it's much more commonly available) the price is as much as 20 euros for a 10 liter container at retail. That equates to $12 per US gallon. Add in the cost of extra maintenance as well as the decreased payload capacity with SCR and the operating cost equation is clearly in favor of Advanced EGR.

Will engine operating temperatures be high with MaxxForce Advanced EGR?

Not at all. Cooling capacity will be sized to keep operating temperatures at optimum levels, just like today. Cooling loads have increased over the years with power increases, air-conditioning, and stringent emissions regulations. Cooling capacity has always kept pace and will continue to do so.

Won't adding an SCR catalyst be just like adding another DPF?

The catalyst itself is only a minor portion of an SCR system. A 10-15 gallon urea tank complete with insulation and heater, and a doser system to meter and inject urea are also in the picture. Taken together, SCR system components will take up more space than a 100 gallon fuel tank and will add 200 lbs. - 300 lbs. weight. Packaging will be a critical challenge, particularly on vehicles requiring clean cab-to-axle space for body mounting.

Will in-cylinder systems be 2010 compliant?

All MaxxForce engines will be compliant for 2010, just as they are today. If they weren't, we couldn't sell them. Some Navistar engines are currently below 2007 NOx levels, as the EPA encourages and rewards this. As a result, we will be able to phase into 2010 emissions regulations with in-cylinder technology because our engines are cleaner, earlier than required. Customers benefit through the longer and smoother transition.

What are the new 2010 EPA emissions requirements?

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.
