2 W HY DIESEL TRUCKS AND BUSES ARE THE BEST THING GOING FOR BUSINESS AND THE ENVIRONMENT Today in the U.S., almost all heavy trucks, medium trucks and buses are powered by diesel. And it s not just because of diesel s unsurpassed power and performance. Here are a few more reasons: Green Diesel Technology vehicles developed by International and IC Corporation, International s wholly-owned affiliate, are the wave of the future. Using the breakthrough advantages of advanced diesel engine technology, particulate filters and ultra-low-sulfur diesel fuel, some engines developed by International have already been certified as meeting the U.S. Environmental Protection Agency s 2007 standards for particulate matter (PM) and hydrocarbons (HC). And there s even more improvement on the way. International s retrofit kits are another part of the emission improvement line of products offered through all authorized International and IC bus dealer locations. You can rest assured all federal guidelines will be met and that we ll continue to provide you with clean trucks and buses that move you ahead, on the road and in your business.

3 RETROFIT SOLUTIONS F ROM INTERNATIONAL International diesel particulate filters (DPF) utilize the latest advancements in emission control technology from Engelhard a world leader in emission technology. Retrofit filters provide: 70-98% reduction in particulate matter (PM) and visible smoke; depending on fuel quality 70-98% reduction in CO and HC Reduced odor Reduced noise Diesel particulate filters from International are passive systems and allow oxidation of PM at normal operating temperatures. Benefits include: Fuel sulfur tolerance. Although we require the use of ultra low sulfur fuel (15ppm), occasional use of higher sulfur fuel in emergency situations will not damage the system or stop the vehicle. Easy cleaning and maintenance. We recommend cleaning and visual inspection once every (12) twelve months or every 60,000 miles/100,000 kilometers. Certain applications may require more frequent service. International systems include a pressure monitor sensor, which will indicate the need for cleaning. Only removal of the non-toxic ash is required to clean the filter. No additional energy devices. DPF systems are designed to be passive systems and regenerate under normal vehicle operating conditions. Effective under most driving conditions. Idling does not substantially affect the performance of the DPF. During idling, very little PM is produced, and the PM that is produced is primarily oil and fuel that the DPF easily eliminates. Adaptability. The DPF is available for use on most diesel buses and medium trucks with electronic engines. Additional information, can be found on the EPA website at What will 2007 federal diesel rules require? The U.S. Environmental Protection Agency s rules for heavy-duty engines mandate a 90 percent reduction in particulate matter (PM) emissions from today s standards, and a 95 percent reduction in nitrogen oxides (NOx). The guidelines also require reductions in emissions of hydrocarbons (HC). While NOx standards and HC standards will be phased in between 2007 and 2010, the PM reduction requirements must be met in full by To support these emission reductions, the EPA requires wide availability of ultra-low-sulfur diesel fuel beginning in Can older vehicles be retrofitted to meet new requirements? Yes. It is feasible to retrofit recent model diesel vehicles with filters to reduce PM. Factors that affect retrofitting include geographic location, duty cycle and engine type. International is examining the best way to provide retrofit options to its customers. How does International set the pace in meeting emissions standards? International partners with customers, regulators and others at many levels, national and state, to develop realistic clean-air solutions. In 2001 we were the first engine manufacturer to receive certification from the EPA as well as from the California Air Resources Board for the engine performance now achieved in our IC Corporation affiliate s new smokeless, odorless Green Diesel Technology school bus, which meets the 2007 requirements for both PM and hydrocarbons. We will continue to work with emerging technologies to meet customer as well as regulatory requirements, such as the NOx levels set by the 2007 standards.

4 INTERNATIONAL EMISSIONS TECHNOLOGY RETROFIT KITS Complete installation kits are available through all authorized International and IC bus dealer locations. Complete kit contains: Filter assembly Pressure monitor kits Tubing Hanger Brackets What about diesel exhaust and health effects? No scientific study demonstrates a causal link between diesel emissions and health effects in humans. One set of studies, involving coal miners, focused on diesel as the primary particle source to which individuals were exposed; it found no adverse health effects. There have been stories in the media covering the alleged effects of diesel exhaust on children who ride school buses. Are these stories accurate? Two reports stimulated media publicity in 2001 and Independent scientists, including the American Council on Science and Health (ACSH), said the reports were unreliable. One study used diesel buses that were at least 15 years old, one of which was likely in serious disrepair. The studies used questionable methods to collect the data and draw inferences about the results. A more reliable study by public school officials in Fairfax County, Virginia, using more accurate and reliable investigating techniques, found no risk to bus drivers or to student passengers. Must any EPA requirements be met before 2007? Yes. Federal rules require manufacturers to produce engines that achieve a 2.5 grams/brakehorsepower-hour standard for nitrogen oxide and non-methane hydrocarbon emissions by Because of consent decrees with the government, some manufacturers must begin to meet this emission standard by October International has a very different agreement with the government, and its engines are not required to meet this standard until the rule becomes effective in 2004.

Diesel has the clear advantage. Compared to gasoline or natural gas, diesel fuel is safe, stable and easy to use, and requires no special handling or storage. Since natural gas is highly flammable, the possibility of fires and explosions is always present, so it must be stored and handled extremely carefully. What can be done to reassure customers about diesel and health effects? Sound science is needed to make rational judgments. International is a leading supporter of scientific research, working with the U.S. EPA, the Health Effects Institute and others. (See Diesel Studies: Just the Facts.) Customers should know the following facts: No scientific research has ever shown that exposure to diesel emissions causes increased health risks. Air pollution in the form of particulate matter (PM) has been associated with increased health risks. However, diesel engines are only one of a great many possible sources of PM; others include gasoline, natural gas and electric power plants, just to name a few. And, since today s new diesel engines already show at least a 90 percent reduction in PM emissions since 1988 and are heading toward zero emissions it s pretty clear that diesel PM emissions are a decreasing factor in particulate air pollution.

6 New research by California government regulators indicates that low-emitting diesel vehicles may have significant environmental advantages over comparable natural gas vehicles. The study conducted by the California Air Resources Board (CARB) produced the following findings: In 8 of 11 categories tested, a low-emitting diesel bus powered by low-sulfur fuel and equipped with a particulate trap produced lower levels of pollutants than a similar transit bus powered by natural gas. Natural gas vehicle exhaust was eight times more mutagenic than diesel exhaust. (Mutagenicity measures the degree of mutation in a cell or organism and is used as a potential health risk indicator for cancer and reproductive health effects.) The natural gas bus discharged more particulate mass, hydrocarbons and carbon monoxide than the low-emitting diesel bus. These new findings are supported by other comparative studies of clean diesel and natural gas, including a comprehensive study conducted by Ecotraffic of Sweden, which found that diesel vehicles have lower greenhouse gas emissions than natural gas, thanks to diesel s superior fuel efficiency. Similarly, a fuel comparison study conducted by the Harvard Center for Risk Analysis in January 2000 noted that the use of natural gas as a motor vehicle fuel may exacerbate the greenhouse gas effect because methane will escape into the atmosphere during refueling operations and at natural gas storage facilities. The Harvard study also noted that methane is approximately 20 times more potent as a greenhouse gas than carbon dioxide. The California Air Resources Board study reinforces the concept that transportation regulatory decisions must be fuel neutral, said Dr. William B. Bunn, Vice President, health, safety and productivity, International Truck and Engine Corporation. Public policies that in any way favor natural gas over diesel should be reconsidered pending peer review of the data in this new study, as well as other research now available. Dr. Bunn commended the California board for undertaking this study and for decisions made by the board in 2001 that recognized the low-emission performance of new diesel engines with advanced aftertreatment technology, using ultra-low-sulfur (below 15 parts per million sulfur content) diesel fuel, now available from BP and other refiners. The performance of a Green Diesel Technology school bus was certified by both the California ARB and the U.S. Environmental Protection Agency as meeting particulate and hydrocarbon standards that will be required in 2007 rules in California and nationally.
