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] high floor [is] ideal for NO x reduction over proposed Low Load Cycle.

Researchers use melamine to create effective, low-cost carbon capture; potential tailpipe application

Green Car Congress

The process for synthesizing the melamine material, published in an open-access paper in the journal Science Advances , could potentially be scaled down to capture emissions from vehicle exhaust or other movable sources of carbon dioxide. The low cost of porous melamine means that the material could be deployed widely.

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.,

MAN Engines releases first IMO Tier III engines for workboats; low-cost, SCR-only solution

Green Car Congress

The solution ensuring compliance with the IMO Tier III limits is MAN Engines’ modular exhaust gas aftertreatment (EAT) system, which was exhibited at the SMM trade fair last year. Two of the variants that are possible due to the installation flexibility of MAN Engines’ modular exhaust gas aftertreatment system.

Berkeley Lab scientists generate low-cost, hybrid thermoelectric materials

Green Car Congress

Scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) have constructed a low-cost, nanoscale composite hybrid thermoelectric material by wrapping a polymer that conducts electricity around a nanorod of tellurium—a metal coupled with cadmium in today’s most cost-effective solar cells.
