Mercedes-Benz powering ahead with €3B strategic engine initiative; increasing electrification, 48V; diesel and gasoline; cylinder deactivation

Green Car Congress

For the mobility of the future, we are deliberately not committing ourselves to one solitary form of drive system, but to a coexistence of efficient and clean petrol engines, diesels, plug-in hybrids, battery and hydrogen drive systems. This allows fuel savings that were previously reserved for high-voltage hybrid technology.

U. Minnesota team develops Lagrangian technique to identify NOx hotspots; opportunity for connected vehicles and big data

Green Car Congress

In this testing, the hybrid bus performed better on the higher speed routes, and the conventional bus performed better on the low-speed route. Conversely, Lagrangian data taken from the vehicle frame of reference can more precisely indicate the spatiotemporal distribution of mobile emissions sources.… Credit: ACS, Kotz et al.

Update on DOE Co-Optima project to co-optimize fuels & engines; goal of 30% per vehicle reduction in petroleum

Green Car Congress

The intended application is light-, medium-, and heavy-duty markets including hybrid architectures. In August 2016, DOE announced funding of up to $7 million further to support the initiative. With the 2016 start date, that gives the team three years to complete the R&D efforts in this area. Earlier post.) Earlier post.)

New aluminum-cerium alloys could boost rare earth production; improved energy efficiency of engines

Green Car Congress

Modern windmills and hybrid autos, for example, rely on strong permanent magnets made with the rare earth elements neodymium and dysprosium. Where high-temperature performance would normally be addressed by the conversion of aluminum to titanium, much higher prices may be justified. McCall, M. McGuire, R.
