Series 6000 DOC & Spiracle (closed crankcase filtration system). Baseline A. |
Highway, heavy-heavy and medium-heavy duty, 4 cycle, non-EGR, model year 1991 - 2003, turbocharged or naturally aspirated | 500 | 25 | 13 | n/a | 52 |
Series 6000 DOC & Spiracle (closed crankcase filtration system). Baseline A. |
Highway, heavy-heavy and medium-heavy duty, 4 cycle, non-EGR, model year 1991 - 2003, turbocharged or naturally aspirated | 15 | 33 | 19 | n/a | 26b |
Series 6000 DOC & Spiracle (closed crankcase filtration system). Baseline B. |
Highway, heavy-heavy and medium-heavy duty, 4 cycle, non-EGR, model year 1991 - 2003, turbocharged or naturally aspirated | 15 | 28 | 23 | n/a | 50 |
a - Total PM reduction figures reflect reductions from both tailpipe and crankcase emissions.
b - Verification test results produced an average HC percentage reduction of 26%. However, the 95% confidence interval included zero so no reduction is assigned.
Baseline A - Baseline assumes an unmodified engine running on regular 2D (<500 ppm sulfur) fuel.
Baseline B - Baseline assumes an unmodified engine running on ultra-low sulfur diesel fuel (ULSD) (<15 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 150° C during 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.
- To meet the conditions of this verification, the Spiracle Closed Crankcase Filtration System requires that the filter cartridge must be changed at every lube oil change recommended by the engine manufacturer or every 500 hours, whichever comes first.
- The engine must be operated with a fuel that contains a sulfur content of no more than the level indicated above.
No discernible fuel economy penalty is expected when used in a compatible application.

The following operating criteria must be met in order for appropriately retrofitted engines to achieve the above emissions reductions:
- The engine must be operated with a fuel that contains a sulfur content of no more than 15 ppm for use with the Series 6100 DOC & Spiracle systems.
- The engine exhaust temperature must be at least 150° C during 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.
