Bulk defective vanadium oxide catalysts remove NOx at lower temperatures

Green Car Congress

Scientists from Tokyo Metropolitan University have developed a low-temperature catalyst for removing NO x gas from industrial exhaust using ammonia. Conversion rate of nitrogen oxides at different temperatures for conventional, V(V) oxide and V(IV)+V(V) oxide “defective” catalysts. Resources.

Volkswagen introduces new Coasting 2.0 micro hybrid system and new natural gas engine at Vienna Motor Symposium

Green Car Congress

At the 38 th Vienna Motor Symposium Volkswagen is introducing a new, more fuel-efficient “Coasting - Engine off” micro hybrid system—which shuts off the engine completely—as well as a new, compact three-cylinder natural gas engine for the Polo. All-electric architecture. Coasting - Engine off. liters/100 km. New e-Golf.

Audi’s new 3.0L diesel; ready for 48V mild hybrid system

Green Car Congress

The cylinder heads have two-part water jackets for needs-based cooling. To optimize the air flow and the fuel mixture preparation, the intake ports (one each for swirl and the other for charging) and the exhaust ports have been modified relative to the predecessor engine. Both ports have lower flow resistance. The further developed 3.0

ETH Zürich, Total team develops new catalyst to convert CO2 and H2 directly to methanol efficiently

Green Car Congress

Scientists at ETH Zürich and oil and gas company Total have developed a new catalyst that efficiently converts CO 2 and hydrogen directly into methanol. Even at the time, it was encouraging that doing so generated virtually only methanol and almost no by-products other than water. The catalyst also proved to be highly stable.

MECA report finds additional NOx emission reductions from new heavy-duty trucks achievable and cost-effective

Green Car Congress

It is important to state that there are several technology paths to achieve these levels of emissions, and some of them can simultaneously lower greenhouse gas emissions, such that the NO x reductions do not compete with the CO 2 reductions.

MECA report assesses technology feasibility for heavy-duty diesel trucks to meet lower NOx standards by 2024

Green Car Congress

In the latter, CARB staff signaled a plan to align the regulatory provisions for the first phase of NO x tightening with the second implementation stage of the Greenhouse Gas Emissions and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles - Phase 2 in 2024. g/bhp-hr and a low-load cycle limit below 0.2

New fuel-efficient bulk carrier concept design; DNV estimates new tankers, bulkers and container vessels will be up to 30% more energy efficient by 2020 than newbuilds today

Green Car Congress

The Green Dolphin concept design is a five-cargo-hold CSR (Common Structural Rules) double-hull bulk carrier that meets current and future expected air and water emissions regulations. Wash water holding tanks are also included. Speed at design draught. Green Dolphin. DNV outlook to 2020.
