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.
Aligning Brazil's new-car efficiency target with the European Union’s target would have substantial benefits for consumers. Compared to a car meeting Inovar-Auto's 2017 target, the average new car sold in 2023 could reduce fuel costs more than 4,000 USD over the lifetime of the vehicle, equivalent to 2.4 times the cost of additional vehicle technology.
A conversation with Dr. Meyer (Mike) J. Benzakein on the importance of developing fuel efficient engines.
