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.)

New ORNL non-precious metal catalyst shows promise as low-cost component for low-temperature exhaust aftertreatment

Green Car Congress

Researchers at Oak Ridge National Laboratory (ORNL) have developed a ternary mixed oxide catalyst composed of copper oxide, cobalt oxide, and ceria (dubbed “CCC”) that outperforms synthesized and commercial platinum group metal (PGM) catalysts for CO oxidation in simulated exhaust streams while showing no signs of inhibition—i.e.,
