Isuzu’s 2009 truck line-up comes with a unique difference you can see. In fact, we actually call it the SEE technology. It stands for Safety, Economy and Environment. Because it drives the core of the engineering efforts, SEE enables us to bring you technically advanced and highly reliable products that perform equally well in your fleet and in our environment.

Safety. Isuzu trucks protect drivers with our stronger and quieter Hexapod cabs, which also offer reduced VOCs in the cabin. Panoramic windshields and side windows afford unsurpassed visibility. Plus Isuzu trucks’ legendary maneuverability helps drivers avoid problems in traffic and on job sites.

Economy. Isuzu is setting the pace to reduce the world’s dependence on oil by already meeting the 2015 fuel efficiency standard.

Environment. Isuzu engines have been proven to meet the needs of society and customers for super-clean power sources that reduce environmental impact. Isuzu engineers are well on their way to developing the next generation D-Core engines that will meet 2010 emissions standards.

For more information on how the Isuzu Truck SEE technology can make the difference in your fleet today and well into the future, contact your Isuzu truck dealer or visit isuzucv.com.

For 2007, the EPA lowered the limit for diesel fuel sulfur from 500 ppm (parts per million) to 15 ppm (that is one of the factors that is motivating the use of biodiesel). This new fuel adds 5¢ to 10¢ per gallon to fuel costs. Phase-in started almost a year ago (September 1, 2006) and will reach 100 percent participation by September 1, 2010.

• Low sulfur fuel has various benefits, like producing less PM from combustion, it enables NOx absorber technology to be highly effective, and it can have a positive effect on oil drain intervals.
• There are two fuels on the market. Use the correct fuel in your truck – in other words, only use the low sulfur fuel in 2007 diesel trucks. Low sulfur fuels can be used in any older diesel engines in your fleet, as well.

When it comes to oil:

• Low-ash oil is being utilized in these engines to extend the maintenance life of the filter. Only use engine oils labeled with the CJ-4 designation. Low-ash oils can be used in any older diesel engines in the customer’s fleet, as well.
• Isuzu engineers designed our emissions systems to work efficiently with these new fuels and lubricants in order to extend maintenance intervals while maintaining the lubricity capability of the lubricant.

Did you know that every 2007i and newer post-emissions Isuzu-built diesel engine vehicle is equipped standard with our exclusive Data Recording Module (DRM)? This is an industry first: to offer as standard equipment a device like our DRM that can monitor vehicle performance and usage data. While some engine manufacturers include this as a part of their engine monitoring system, our DRM records data from multiple areas of the vehicle. Isuzu’s vehicle operational data can be downloaded at the dealership and shared with you to help reduce operating costs and improve vehicle uptime.

The data recovery capabilities of the DRM are fully represented in the Vehicle Health Report that has been developed by Isuzu Commercial Truck of America. Information collected from the DRM and displayed in the Vehicle Health Report can be used by owners to reduce operating costs and improve the efficiency of their transportation assets. The date range of data is selected and the information stored within the DRM is displayed on the IDSS computer screen. The Health Report can then be printed and shared with you. The Health report is configured in an easy to read and understandable format.

Health Report Features:

• Simple Green/Yellow/Red report format warning indicators
• Fuel economy chart
• Vehicle speed chart
• Braking deceleration chart
• Engine coolant temperature chart
• Engine load chart
• DPF regeneration efficiency
• Power Take-off utilization chart
• Engine idle time chart

Health Report Benefits:

• Identifies driver patterns and trends
• Can help improve safety and driver performance
• Can compare vehicles within fleet to identify component or driver problems
• Increases used truck value by providing vehicle life history
• Improved vehicle diagnostics for reduced downtime

Isuzu 4H and 6H engines use an advanced Exhaust Gas Recirculation (EGR) system and a variable geometry turbocharger.

The EGR system recirculates a portion of an engine’s exhaust gas back to the engine cylinders. Intermixing the incoming air with recirculated exhaust gas dilutes the mix with inert gas, reducing the amount of excess oxygen.

Because NOx formation progresses much faster at high temperatures, EGR serves to limit the generation of NOx. One negative byproduct of EGR is an increase in particulate matter – but Isuzu trucks have tackled that challenge with the Diesel Particulate Filter (DPF).

EGR increases the amount of PM… then the DPF filters out the additional PM. But what happens if it gets clogged?

Isuzu engineers figured out the answer – so to prevent the DPF from clogging, the trapped particulates are burned off and the filter is cleaned using a high temperature regeneration process – approximately 1000°F in the Particulate Filter – that leaves a harmless ash as a residue.

Here’s what you need to know – with this system, there are two types of regeneration:

1. Automatic Active Regeneration – this occurs automatically when the exhaust gases reach the optimum temperature. This occurs as the truck is driven throughout the day and requires no involvement by the driver.
   • The driver will know when this is occurring because the green “Active Regeneration – Automatic” light will be illuminated on the instrument panel.
2. Manual Active Regeneration – if vehicle operation does not produce exhaust gases that are hot enough for automatic regeneration, a control light will indicate the need for regeneration.
   • The yellow “Active Regeneration – Manual” light is illuminated on the instrument panel signaling a partially clogged filter. If the yellow light is ignored, it can turn red, an audio chime will sound and the engine will go into a reduced power mode to prevent damage to the system.
   • If the red “Active Regeneration – Manual” light is illuminated on the instrument panel, it signals a clogged filter.
   • An orange “Active Regeneration” light indicates the reduced power mode.

Here is how the driver can initiate the regeneration process:

• Drive the vehicle above 30 miles per hour until the yellow indicator light goes off… or…
• Place the truck in Park with the parking brake on, then press the Regeneration switch – the switch will illuminate, indicating a regeneration is initiated when complete, the light will go out. Remember, during regeneration, the exhaust parts and gasses may become very hot when idling in Park – make sure the exhaust system area under the vehicle is clear of material that could burn or ignite.

Regeneration requires much hotter exhaust gases than those experienced on previous diesel-powered vehicles – we are able to retain the heat within the exhaust system by utilizing dual-wall air gap pipes, an insulated catalyst and DPF filter end cones. Consequently, pipe and component exterior skin temperatures are not much higher during regeneration than they are today.

Even though the filter is designed for long life, eventually the accumulated ash must be removed by special cleaning equipment at your dealership. To precisely control engine combustion and DPF regeneration, we have developed special system sensing and control software.
