What kinds of diesel vehicles are eligible to participate?

Project Green Fleet installs pollution control equipment, idle reduction technologies and replaces older engines with new, cleaner running engines on a range of diesel fleets including, but not limited to:

• Dump trucks
• Cement mixers
• Off-road construction equipment
• Trains
• Port facility fleets

Will the equipment impact my existing warranty?

Installation of pollution control equipment has no effect on a vehicle’s existing warranty. Certified engine repowers are done with manufacturer’s certified equipment and installers, so that the existing warranty remains intact.

Does the equipment have any impact on vehicle performance?

According to the U.S. Environmental Protection Agency’s voluntary retrofit program, oxidation catalysts and closed crankcase filtration devices have minimal impact on a diesel vehicle’s performance and fuel economy. Some of the other retrofit technologies have a minimal impact on performance

What kind of maintenance does pollution control equipment require?

Depending on the technology that is installed, there will be varying levels of maintenance required.  For example:

• Diesel Oxidation Catalyst - No maintenance
• Closed Crankcase Filtration System – Filter change, twice per year
• Diesel Multi-Stage Filtration System – No maintenance, but must operate with a minimum exhaust temperature.
• Diesel Particulate Filter – Requires periodic cleaning by a special machine, most maintenance intensive
