Bosch says it has solved diesel NOx problem; as low as 13 mg NOx/km even under RDE; refining existing technologies

Green Car Congress

But even today, vehicles equipped with Bosch diesel technology can achieve as little as 13 milligrams of NO x in standard legally-compliant RDE cycles. A dynamic driving style demands an equally dynamic recirculation of exhaust gases. To ensure optimum NO x conversion, the exhaust gases must be hotter than 200 degrees Celsius.

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

Current Legal Requirement for Use of Anhydrous Ethanol in the United States. The result is more efficient combustion, cooler running engines, lower exhaust temperatures, and increased longevity of engine life. Until fairly recently, these US motor vehicles were non-FFVs. 40 CFR § 80.27 Pursuant to 40 CFR § 80.27(a)(2):

“Energiewende” in a tank; Audi e-fuels targeting carbon-neutral driving with synthetic fuels from renewables, H2O and CO2; Swiss policy test case

Green Car Congress

Audi’s basic goal is to combine renewable energy (e.g. Energiewende”, the term applied to Germany’s policy of transitioning to an energy portfolio dominated by renewable energy (as well as a shift to more distributed generation), thus also applies to the vehicle fuel tank for Audi’s e-fuels, Mangold suggests. Earlier post.)

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

For offsets to be credible, a ton of CO 2 -equivalent emissions from an offset project should equate to a ton reduced from a covered emission source, such as a smokestack or exhaust pipe. 2) Examples of Renewable Energy Projects. Use of renewable sources would avoid emissions that would have been generated by fossil fuel combustion.

IEEE Discusses 6 Simple Solutions to Climate Change at COP27

Cars That Think

At COP27, he said that even though the first legally binding international treaty on climate change, known as the Paris Agreement , was adopted nearly a decade ago, countries have yet to come to a consensus on how to stop burning fossil fuels, among other issues. Another efficient option he pointed out is the combined cycle power plant.
