By the side of the road...

A very good analogy Chris.. Imagine how stinky and objectionable it would be by then...

The only vehicles I can see it really making any sense for would be things like long distance coaches - as they're going to chuck out a lot of crud chugging around town, but also spend a lot of time on the motorway.

...Moot point though as virtually all vehicles like that use SCR anyway as far as I'm aware.

Curiosity got the better of me had to look it up...
What is Selective Catalytic Reduction?

Selective Catalytic Reduction (SCR) is an advanced active emissions control technology system that injects a liquid-reductant agent through a special catalyst into the exhaust stream of a diesel engine. The reductant source is usually automotive-grade urea, otherwise known as Diesel Exhaust Fluid (DEF). The DEF sets off a chemical reaction that converts nitrogen oxides into nitrogen, water and tiny amounts of carbon dioxide (CO2), natural components of the air we breathe, which is then expelled through the vehicle tailpipe.
Now, doesn't that sound absolutely delightful :!: :-D (has anyone invented an actual sarcasm emoticon yet!)
automotive-grade urea
Is that a euphanism for concentrated p*ss :?: :-D

Selective catalytic reduction. Have to confess that it was years ago that I last read through the operational principles, so I can't recall whether it concentrates on the gaseous output to particulates (or both).

Have never seen any smoke to speak of from any of the buses that First or Bluebird had using SCR kit though to be honest, so have to guess it does something!

DPF obviously wouldn't really work for a bus destined for urban service would it as it will never be able to do a "natural" regen cycle.

Know the training bus (cast off from the main fleet) had very nearly gone round the clock yet had never operated outside Aberdeen City in its whole life! Would probably have been about 10 years old I think when I drove it.

Sorry Neil :oops: , I'm just off to Specsavers :lol:

So, if I understand correctly, this is what Adblue does...

Had to look that up as well Jim :-D

Apparently so, even good old Volkswagen use it on their cars so we can all rest easy in our beds knowing that every 600 miles or so, to keep the exhaust coming from the tailpipe clean enough to breath in, they consume 1-1.5 litres of Adblue (Urea and water apparently so maybe not as I first thought concentrated p*ss, but really actual p*ss.)
The size of the AdBlue® tank fitted to your car will vary depending on which Volkswagen model you have, therefore the interval between top-ups will vary. In addition, many factors such as mileage, journey type, driving style and environmental conditions can influence how much AdBlue® is consumed. A passenger car can consume approximately 1.5 litres of AdBlue® every 620 miles (1.0–1.5 litres for the Passat and Passat Estate).

:lol:

Given that level of consumption I can now understand why garage forecourts always have stacks of Adblue on display!

Must be a very cheap product to make...

If it is expensive then someone is taking the p!!!

But can you trust Volkswagen after Dieselgate though?

Which is how they come by their supplies!

I recall many years ago someone came up with a centrifugal device that fitted to the exhaust and spun out the particulates.

AdBlue here (or at least a similar product) is actually made by several of the local agricultural fertiliser companies.

A very good description of Diesel Exhaust Fluid on Wikipedia:

It involved holding the crankshaft still, and letting the car spin up to speed. :rofl2:

:-D :-D .

I think it was really an adaption idea taken from the centrifugal oil filters fitted to some Italian (I think, Fiat maybe) cars.

I fondly remember the days when there were lots of spurious stuff on offer like that - mostly devices to magically transform performance and economy by massive amounts for very little outlay... An allied device to the one you mention was on that fitted to the inlet and was alleged to act like a turbocharger!

And then there were those lead pellets you could pop in your tank to magically raise the fuel octane level to hitherto untold values...


The world has been a significantly duller place since they all disappeared - victims no doubt of advertising standards :(
