SLOW DOWN...!!!!!!!!!!!

NOx
In atmospheric chemistry, NO x is a generic term for the nitrogen oxides that are most relevant for air pollution, namely nitric oxide (NO) and nitrogen dioxide (NO 2 ). These gases contribute to the formation of smog and acid rain, as well as affecting tropospheric ozone.

edit: late posting. nvm

Just to add to this ... it is produced by the combustion of fuel at high temperatures, especially in engines and leads to a range of pollutants that form things such as acid rain and smog; the latter being particularly damaging to people with lung conditions such as smog. The legal limits of NOx in the atmosphere have been exceeded for some time now ... it is costing the country £millions if not more in health care, lost productivity etc.

Its basically to try and stop smog forming over residential areas. It's very bad for the health of anyone who has to live in it. Personally I don't care about China. I do care about my young nephew and niece who happen to leave near the A34 in Oxford.

Presume you've sold your motorhome & taken up cycling then?

If they don't want loads of noxxes sort the flippin traffic jams out.

As Guigsy said but the NOx is not the only pollutant from vehicles. The only sustainable way of sorting out traffic jams is taking vehicles off the roads and reducing the vehicle mileage. One of the biggest things gained by reducing jams is more traffic. More traffic = more pollution.

May I ask what chassis and gearbox ?
 
I don’t know anything about NOx,but it’s obvious that,if you’re in a motorhome,it’s a waste if time going more than lorry speed ie 56mph true speed.

We travelled to Norfolk on the 9th July via the A1065 and were followed by a funster who insisted on driving right up my jacksie. I wasnt driving slowly. He was so close that I could clearly see his small FUNSTER sticker on his windscreen. Why? Was it you? Crazy! Stay back,sit back,relax!

On my return journey I did the 98 miles in 2 hours 15 minutes and never went over lorry speed.

When will people realise that you don’t need to try and gather the haemorrhoids of the driver in front in order to make good progress??!! Save the planet,slow down.

OK I’ll show my stupidity what’s all that about?
 
This takes me back 30 odd years when working at an Oil and Gas Fired power station.

We used to call it the NOx and SOx's routine to check all the flue gas analysers

Actually, you get worse NOx when the traffic is moving quickly. It's only a problem at high loads and revvs.

Is it or is the high load revs whilst pulling away quickly reving the engine to get going. Or does that depend on who you believe. Money makes, or reality. A vehicle isn’t at high load once doing 60-70, only when getting there.

?wasnt me,I was on the 1088 and 1066

NOx emissions are bad for local air quality. NOx are generated when an engine is running at higher revs under load.

Genuine question......at 70mph my car is doing hardly more than 2200 revs.....not really under load or working hard....therefore.......is it producing any more than when I do 50mph......and is it not worse to have buses/cars doing lower speeds at potentially cyclical higher revs in urban areas?

Why is it getting worse when we now have super duper low emission cars, cats, computers and adblue, plus the electronic vehicles.
I Don't know why we don't go back to horses.
 
There are too many vehicles that don't meet high emissions standards and don't forget, all vehicles emit pollution through their construction & operation. Some more than others.
 
Dread to think what Stevenson , Brunel , watt and their contemporaries would think of this stuff if they could see how all the inventions that made this country, " great " are slowly being thrown aside in the name of progress.
The only place we are progressing to is the third world. :(

Go on then I'll bite again, how does construction make a difference?

Hi Gus. I get what you’re saying here. My Fiat 3 ltr is a great engine, but sometimes it’s just better in fifth or fourth than keeping it in sixth. Even the hand book says it’s better running at 2/2.8k revs. More efficient I guess.

70mph then(y)

Transit pvc 330 mwb 110 5 speed. Cruise will drop out at 80 kph in top on the slightest slope. Same in 4th drops out at 60kph.

Depends on the legal limit for the road and circumstances. Not necessarily 70mph.

My guess is that they would be at the forefront of developing new sustainable technologies.

Construction accounts for up to 22% of a vehicle's CO2 emissions (mean 10% approx) through the extraction, transport and conversion of components such as iron, glass, plastic etc.

What's that got to do with a speed limit on a motorway? :unsure:
