End of the road for diesel cars?
britishtrident - 30/4/15 at 03:40 PM

Following the latest supreme court judgement looks like diesels cars will be taxed off the road to reduce NOx and particulate pollution.

Shame it will also affect all modern diesels that use Adblue, which actually reduces NOx by 80-90%...

I was reading something the other day that described how some scientists have managed to make a diesel-like fuel from atmospheric CO2 & solar power - I wonder how the scare-mongers will deal with that when it becomes commercially viable! (if it does)

The Fischer–Tropsch process was invented in the mid-1920s, so there's nothing really new here. Possibly some process improvements I guess.

Adblue is horrible stuff we use it at work it rots aluminium and electric cables and if you spill it on concrete it goes like crystals we call it pig piss

I'm sure I read something in a car magazine a few years ago that too many cars were in the lower tax brackets and that we were going to have changes anyway.

They'll have to ban all the DI petrols to go with it, their particulate emissions are worse than the diesels, and are directly absorbed through the skin due to being smaller than the diesel particulates, and also have high NOx levels when running lean stratified combustion.
Burning wood is to become a no-no with its particulate emissions accounting for over a third of worldwide particulate emissions.

In reality, there will be alot of industrial diesel equipment being retrofitted with adblue and particulate filter systems, a few old bangers taken off the road sooner than expected, but don't expect the enviromental groups to highlight the woodburning emissions to the supreme court any time soon!

A modern diesel with DPF and SCR setup has zero particulate emissions, and extremely low NOx and SO2, so will be unaffected by any of this, having a barbecue is more likely to be banned first.

Well the BMW 330 M coupe I want to buy has not dropped in price
YET

currently in London reducing the emissions of said London buses fitting SCR systems.

WHAT A LOAD OF BOLLOX.

airplanes make more nox , as does electricity generation and heating peoples homes .

yep, but as always vehicles are easy targets... despite their impact being much smaller percentage-wise.

I've always wondered how cars with carbs do on NOx and particulates etc... but I never found any reliable figures

My old 106 barely registered on the CO and HC tests (0.1% and 3ppm) and it could do 65mpg on the motorway - not bad for a 1992 car with single choke carb and 4 gears

Thing is you can abate the NOx from combustion plants. Some of them run at levels significantly lower that what the EA sets. You cannot do much with cars
