† - Baseline assumes an unmodified engine running on regular 2D (<500 ppm sulfur) fuel.

Notes:

  • This verification applies to summer blend PuriNOx only.
  • A negative value in the table above indicates an increase in that pollutant.
  • Summer blend PuriNOx cannot be used in ambient temperatures below 20° F.
  • Under proper storage conditions PuriNOx has a storage life of 12 months.
  • End use applications must be tolerant of up to a 20% power loss when operating at maximum engine horsepower.
  • The typical end user will experience a 15% increase in fuel consumption for equipment operating on PuriNOx fuel.
The following operating criteria are required to be met when PuriNOx is used:
  1. PuriNOx is not compatible with optical or conductivity-type fuel sensors.
  2. Engines operation on PuriNOx must be run for at least 15 minutes every 30 days.
  3. End use applications must be tolerant of up to a 20% power loss when operating at maximum engine horsepower.
  4. Seals, gaskets, and materials used in equipment or engine fuel systems that are not compatible with diesel fuel are also not compatible with PuriNOx.
  5. The engine fuel filter must be changed after the first 24 hours of operation on PuriNOx.
  6. PuriNOx is compatible with most typical diesel fuel filters. PuriNOx is not compatible with water absorbing water separators, water absorbing fuel filters, or centrifugal style water separators.
