Between minuscule electric vehicle (EV) sales, growing diesel shares, and Italian carmakers’ struggle to curb carbon dioxide (CO2) and nitrogen oxide (NOx) emissions, there is no doubt that Italy is heading in the wrong direction, but it’s not too late for a U-turn.
A first-of-its-kind event in which several trucking fleets are showcasing highly efficient tractor-trailers in real-world operations, to culminate at the North American Commercial Vehicle inaugural show in Atlanta in September 2017.
The success of the RDE regulation will depend on the will of manufacturers to prove that they have learned a lesson from Dieselgate by beginning to focus on reducing real-world emissions, not just on passing a particular test.
One of the key challenges faced by engine and airframe manufacturers in developing fuel-efficient products is the looming risk that their significant investment will not pay off. The more this risk is lowered, the better the chance that we will see a much-needed improvement of aircraft fuel efficiency. In this final post of the series, we explore ways to lower the risk faced by these risk-averse industry players.
To lead the way in effectively controlling emissions from non-road vehicles, it is crucial for China to advance the China IV standards, as more stringent requirements on emissions will always lead to more advanced emission control technology. Thus, China would be wise to adopt the combination of the Tier 4 final emission standards (including covering non-road equipment of all sizes) and DPF requirement directly as the new China IV emission standards to effectively control PM and NOx emissions.
An interview with Dr. Fay Collier, Associate Director for Flight Strategy, Integrated Aviation Systems Program at NASA Aeronautics and a former Project Manager at NASA Environmentally Responsible Aviation (ERA), on NASA’s contribution to technologies already in use on aircraft flying now, the ERA project, and a new NASA initiative to demonstrate these environmentally responsible aviation technologies.
