Though not surprising Diesel technology, realistically can not be binned overnight when R&D commences years before release
Can anyone see zero emmision Automonise bubbles commuting the nation.......really!
Good to read examples are well within test limits, but does appear to be a bit of cherry picking to me.
Wonder what NOx levels are like, in a heatwave, rather than in the cold which favours low NOx? How about a worst case scenario, hot days and in city stop-start driving? The one that really changes air quality.
IMO, we still really need a more rounded test regime, including as the engines age and are running high mileage.
It's not really a surprise. Manufacturers, especially the Germans, will not abandon diesel overnight. With improved emission technology pollutants, such as Nox, will eventually be reduced to insignificant levels. The recent anti diesel and fossil fuel campaigns have been driven by hysteria and activists such as Friends of the Earth. IMO diesel will be around for quite a while yet. Electric vehicles are fine, but when there is insufficient infrastructure and fast charge points for mass use it's still impractical, apart from city centre travel.
I think Bosch said that if there was a desire the exhaust temperatures can be managed so that there truly are zero NOx emissions from diesel cars. It's just that the politicians basically decided the way forward without consulting the people they should have.
It will be interesting to see how the exhaust temperatures can be managed. I assume that means a heater in the exhaust system and a way of controlling the heater's output? I'm left wondering just how more complicated can exhaust systems get.
I think I'll google this Bosch/zero emissions idea, see if there's some interesting reading.
The small amount of detail I could find, when Bosch made comment a few months ago, was said to be with existing technology. Just how it is implemented. which begs the question why wasn't it already being used? When the industry knew they were way too high on NOx levels in many cars.
I'll have to have an other look as well.
A quick google came up with this:
It's a press release from April 2018.
