Criteria to achieve emission reductions

The following criteria must be met in order for appropriately retrofitted engines to achieve the aforementioned emission reductions:

  1. Baseline engine must be in a certified configuration and operating on fuel with less than 15 ppm sulfur.
  2. The engine exhaust temperature must achieve at least 200°C at some point in the duty cycle.
  3. The engine/equipment must not be equipped with a crankcase oil burning system.
  4. The engine should be well maintained and not consume lubricating oil at a rate greater than that specified by the engine manufacturer.
  5. The engine must not have been originally certified or equipped with a DOC or diesel particulate filter.
  6. For constant speed engines in stationary applications, Nett Technology Inc. is responsible for working with end-users in determining the engine’s eligibility and compliance with applicable federal, state, and/or local regulations.
