DNOx® marine reduces NOx by diluting
the charge air with recirculated exhaust
gas. A well controlled air and exhaust
mixture reduces the peak combustion
temperatures and the NOx emissions,
while still maintaining engine performance.

The control system monitors the soot loading of the filters and the EGR flow is alternated between the two filters
depending on the need for regeneration.
When one filter is being regenerated,
the EGR flow is directed through the
other in a fully automated process.

The amount of NOx that is reduced
depends on the engine. However, 35
to 40% reduction is a minimum in the
ISO 8178 E3 cycle.
