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.

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.,

PowerDriver simulations predict thermoelectric exhaust waste heat recovery output of 300W, -2.5% in fuel consumption; prototyping begins

Green Car Congress

The European Union-funded PowerDriver project—a two-year, €3-million (US$4-million) research project initiated in February 2012 to turn exhaust gas waste heat into electricity using thermoelectric generator (TGEN) technology—has completed simulation work on on a potential automotive application.

IPG to demo Flameless Ceramic Turbine for clean, off-grid power in EV charging

Green Car Congress

But, in many high-use areas and remote locations, upgrading grid connections to meet future charging demand is not practical or commercially viable. Low-cost ceramics enable temperatures beyond the limitations of metals to deliver fuel efficiencies of power plants in small-scale distributed power.
