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.
- 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 for the Spiracle Closed Crankcase Filtration System in order for appropriately retrofitted engines to achieve the above emissions reductions:
- Blow-by rates must be measured and recorded on each vehicle prior to Spiracle installation before selecting the applicable Spiracle model based on the chart provided below.
- The filtered oil from Spiracle must be returned back to the engine oil sump. There is no catch bottle to be used with the Spiracle system.
- International DT444 engines require the installation of the Spiracle Boost using venturi technology to increase the turbo intake vacuum force acting to overcome the filter restriction.
- Spiracle systems require that the filter cartridge must be changed in accordance with the maintenance schedules noted below.

Notes:
- (1) HP rating is given as approximation of Spiracle sizing, but selection is based on blow-by flow rates.
- (2) Filter change interval for P603746/S040004 and P603568/S040005: Every lube oil change or 500 hours, whichever comes first.
- (3) Filter change interval for P607673/S040020 and P607673/S040004: 1000 hours or at 8” H20 if using indicator.
- (4) Filter change interval for P607673/S040020 on Navistar DT444: 1000 hours or at 1” H20 if using indicator.
- (5) Donaldson offers generic and custom installation kits. Generic kits include mounting brackets and connection fittings. Custom kits include generic components plus tubing and clamps.
