Exhaust and aftertreatment on the Achates ULNOx heavy-duty opposed-piston diesel
Exhaust and aftertreatment on the Achates ULNOx heavy-duty opposed-piston diesel x (ULNO x from the opposed-piston engine, which reduced the requirements for the aftertreatment system (ATS). The original aftertreatment system design—which was configured and tested by engineers from Achates Power, Faurecia, Aramco Services, Corning, Southwest Research Institute, and BASF—included a light-off SCR using gaseous ammonia, closely coupled to the engine in the engine compartment, and an under-cab ATS that included a DOC and SCR on filter. However, during development, the project team was able ...
