† - Baseline assumes an unmodified engine running on regular 2D (<500 ppm sulfur) fuel.
The following operating criteria must be met in order for appropriately retrofitted engines to achieve the above emissions reductions:
- The engine exhaust temperature must be at least 225° C during 15% of the duty cycle.
- The engine should be well maintained and not consume lubricating oil at a rate greater than that specified by the engine manufacturer.
No discernible fuel economy penalty is expected when used in a compatible application.

† - Baseline assumes an unmodified engine running on regular 2D (<500 ppm sulfur) fuel.
The following operating criteria must be met in order for appropriately retrofitted engines to achieve the above emissions reductions:
- The engine exhaust temperature must be at least 225° C during 20% of the engine duty cycle for engines operating on ultra-low sulfur diesel fuel (ULSD) and 225° C during 40% of duty cycle for engines operating on current highway diesel fuel (sulfur content of less than 500 ppm). As there may be significant variations from application to application, CDT will review actual vehicle operating conditions and perform temperature data-logging prior to retrofitting a vehicle with this system.
- The engine should be well maintained and not consume lubricating oil at a rate greater than that specified by the engine manufacturer.
- CDT installs a back-pressure monitor and malfunction indicator light on all vehicles equipped with this system until such time as EPA is convinced that monitoring system installation is no longer needed.
No discernible fuel economy penalty is expected when used in a compatible application.
