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.

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. Earlier post.)

Borla Performance Industries developing muffler/membrane unit for exhaust water extraction with ORNL nanopore membrane technology

Green Car Congress

Borla Performance Industries , a leader in the design and manufacture of stainless steel performance exhaust, has an option to license a novel nanopore membrane technology developed at Oak Ridge National Laboratory (ORNL). For the recovery of previously wasted energy from relatively low temperature (.

ClearFlame Engine Technologies completes on-road demo of Class 8 truck with Cummins X15 running E98 ethanol

Green Car Congress

Low-sooting fuels allow for the elimination of diesel particulate filtration (DPF). Use of soot-free “Clear” Exhaust Gas Recirculation (EGR) can allow for lower NOx emissions without the competing soot constraint, meeting next-generation emissions standards without added aftertreatment complexity.
