A Solution to Diesel NOx Problem Comes too Late as EV's Take Off

Breakthrough: new Bosch diesel technology provides solution to NOx problem

Bosch CEO Denner also calls for transparency on fuel consumption and CO2 emissions

Me, "I still think all car and truck producing companies should transition to Battery Electric Vehicles (because it is a Superior Technology to Internal and Diesel combustion engines. It has less maintenance issues, longer driver ownership, better resale value, 'if it still drives your okay on purchasing it, even if you have to buy a new battery pack, a high mileage used electric car costs a lot less, with all the above benefits than a high mileage used Combustion Engine car, which tend to breakdown more often with age.' and, of course, a Battery Electric car creates a lot less pollution). But I decided to add this article to my Facebook friends page to be fair to Diesel Engine fans. This article shows there are still technological leaps for Diesel Engines, if your into that thing."


 From article, (“There’s a future for diesel. Today, we want to put a stop, once and for all, to the debate about the demise of diesel technology.” It was with these words that the Bosch CEO Dr. Volkmar Denner, speaking at the company’s annual press conference, announced a decisive breakthrough in diesel technology. New developments from Bosch could enable vehicle manufacturers to reduce emissions of nitrogen oxides (NOx) so drastically that they already comply with future limits. Even in RDE (real driving emissions) testing, emissions from vehicles equipped with the newly premiered Bosch diesel technology are not only significantly below current limits but also those scheduled to come into force from 2020. Bosch engineers achieved these results by refining existing technologies. There is no need for additional components, which would drive up costs. “Bosch is pushing the boundaries of what is technically feasible,” Denner said. “Equipped with the latest Bosch technology, diesel vehicles will be classed as low-emission vehicles and yet remain affordable.” The Bosch CEO also called for greater transparency with regard to the CO2 emissions caused by road traffic, and called for fuel consumption and thus CO2 emissions to be also measured under real conditions on the road in the future.

Since 2017, European legislation has required that new passenger car models tested according to an RDE-compliant mix of urban, extra-urban, and freeway cycles emit no more than 168 milligrams of NOx per kilometer. As of 2020, this limit will be cut to 120 milligrams. But even today, vehicles equipped with Bosch diesel technology can achieve as little as 13 milligrams of NOx in standard legally-compliant RDE cycles. That is approximately one-tenth of the prescribed limit that will apply after 2020. And even when driving in particularly challenging urban conditions, where test parameters are well in excess of legal requirements, the average emissions of the Bosch test vehicles are as low as 40 milligrams per kilometer. Bosch engineers have achieved this decisive breakthrough over the past few months.)
