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

Green Car Congress

opposed-piston (OP) heavy-duty diesel engine achieved Ultralow NO x (ULNO x ) performance results. A key element of the achievement is the low engine-out NO x from the opposed-piston engine, which reduced the requirements for the aftertreatment system (ATS). Earlier post.)
