10 things to know
about the new
diesels
The new rules cover engines made from Jan. 1, 2007
All manufacturers must meet the new diesel rules. Everyone now sells Clean Diesel
Particulate traps, oxidizing catalysts and cooled exhaust gas recirculation are now
components of all MD truck engines. Isuzu engines have used these components for years
in Japanese-market trucks
Particulate traps clean themselves when they are hot enough, such as in highway operation
in warm weather. When they don’t get hot enough, special engine controls will cause them
to be cleaned by injecting extra fuel into the exhaust. In some conditions, trucks will have to
be idled while this operation occurs
Emissions components in the exhaust system can’t be moved or eliminated. Body builders
will have to work around the exhaust components
After extended use (estimates are typically greater than 100,000 miles), the particulate
filters will need to be cleaned out
Most manufacturers expect the new engines to have comparable fuel economy to the
previous systems. GM and Isuzu engineers have enhanced fuel efficiency with new
6-speed automatic transmissions on many models, and expect better fuel economy in the
new trucks
Ultra-low sulfur diesel fuel is needed with the new equipment. That’s all you can find at any
stations now. It works fine in older diesel trucks
New oils have been developed to work with the new diesel engines. Make sure your
customers don’t use older non-approved lubricants
Only GM and Isuzu offer an alternative: low-cost, efficient and reliable gasoline-powered
medium duty trucks in both conventional and low cab forward designs
