BMW Group Production leveraging virtual reality and augmented reality applications

Green Car Congress

BMW Group Production is focusing increasingly on easy-to-use and effective virtual (VR) and augmented (AR) reality applications. In production, these images are powerful tools in numerous use cases in training and qualification, planning of workstations at the assembly line, or quality control. Target/actual comparisons in operations.

Study finds total greenhouse gas footprint of blue hydrogen “quite high” due to fugitive methane

Green Car Congress

However, a new lifecycle study by a team from Stanford University and Cornell University has concluded that total greenhouse gas emissions from the production of blue hydrogen are quite high, particularly due to the release of fugitive methane. —Howarth and Jacobson.

SwRI CAT-DEF reduces heavy-duty diesel emissions to meet CARB 2027 NOx requirements

Green Car Congress

CAT-DEF—Catalyzed Diesel Exhaust Fluid—is an SwRI-developed catalyst- and surfactant-modified diesel exhaust fluid (DEF) solution. urea-water solution—is injected into the exhaust stream and ideally decomposes to form ammonia, which reacts with NO x on the SCR catalyst to form N 2 and H 2 O. DEF—a 32.5

Fraunhofer researchers developing ammonia-based systems for mobile energy in infrastructure, transportation and industry

Green Car Congress

In comparison to hydrogen, liquefied ammonia makes it easier to transport large volumes to wherever it is needed. In the integrated process, it is possible to achieve an efficiency of 90% in comparison to 70% achieved with conventional technologies. This is particularly important for mobile and space-constrained applications.

On the other hand, however, the lower exhaust gas temperatures result in a lack of energy for their propulsion on the exhaust side. Comparison of turbocharging systems. The cost of a hydrogen powertrain in series production could be comparable to that of a gasoline engine. —Vincenzo Bevilacqua.

Mercedes begins sales of new 6-cylinder GLE diesel; first SUV in its class to meet Euro 6d

Green Car Congress

Certification in accordance with the Euro 6d standard (RDE stage 2) not prescribed for new models until 1 January 2020 is possible due to measures including extended exhaust gas aftertreatment with an additional underbody SCR catalytic converter including ammonia slip catalyst (ASC) in the underbody.

Study finds high exhaust temperatures within NTE operation for heavy-duty diesels with aftertreatment systems contribute to high nanoparticle concentrations

Green Car Congress

The transient results illustrate the gradual formation of the nucleation mode particles with continuous increase in exhaust temperatures. The particle number count under those conditions increased by more than an order of magnitude in comparison to DPF-out particle concentrations. Credit: ACS, Thiruvengadam et al. Click to enlarge.
