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.

Study links deterioration of concrete and asphalt to trace quantities of organic matter; diesel exhaust, windshield washer fluids

Green Car Congress

These deteriorated structures are unsafe for their intended purposes; rapid deterioration reduces the expected lifespan of structures, thereby increasing the costs for maintenance or replacement. During their experiments, the scientists happened to notice that a strange odor developed when commercial cement was mixed with water.

Transient Plasma Systems says advances are bringing plasma ignition technology closer to commercialization

Green Car Congress

Traditional ignition systems when used to enhance internal combustion engine (ICE) efficiency and lower emissions are handicapped with high energy consumption and poor durability leading to an unattractive cost of ownership. For advanced ignition systems to be adopted, cost, size and lower energy consumption are critical.

JERA and IHI to demo ammonia co-firing at a large-scale commercial coal-fired power plant

Green Car Congress

This will be the world’s first demonstration project in which a large amount of ammonia will be co-fired in a large-scale commercial coal-fired power plant. Ammonia enables efficient, low-cost transport and storage of hydrogen. The project will run for approximately 4 years from June 2021 to March 2025.

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.,

Stena Line seeking novel approaches to recover energy from exhaust gases from ship engines

Green Car Congress

Stena Line is seeking novel, cost-effective approaches to recover energy from exhaust gases from ship engines and to transform it into a more useful energy form (e.g., The company is also interested in efficient turbine systems that generate electricity from the kinetic energy from the massflow and velocity of the exhaust gases.

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.
