Exhaust and aftertreatment on the Achates ULNOx heavy-duty opposed-piston diesel

Green Car Congress

However, during development, the project team was able to exceed the program expectation for engine-out NO x and exhaust temperature control in the catalyst warm-up mode and concluded that the tailpipe NO x targets can be met without the close coupled light-off SCR. The OP engine operates at nearly ideal temperature range.
