Never underestimate the power of stupid people in large groups.

PSA Group diesel engines (Peugeot, Citroen, Ford, Jaguar and Land Rover) have relied on urea to regenerate their catalysts for nearly ten years.

I've had 4 Landrovers over the past 10 years, and never had to fill a Urea tank.


Whereas the Quattro actually has a little filler point next to the filler er, point..

The older PSA engined cars usually had a sealed canister hung under the car which is disposable and dosed the catalyst at preset intervals. Once empty it needs replacing (a light comes on the dash). They are however a regular service item and are changed as a matter of course at major services so most folk who get their car dealer serviced never see the light or have anything to do with the system. You don't have to fill them up as such.

The latest Euro 6 engines need much more urea injected than previous versions to regenerate the catalyst(s) more often to maintain lower emissions so the move has been towards refillable tanks in the last couple of years.

European trucks have been using adblue for a while now to clean up diesel emmisions and are starting to become more common in Oz. They have a separate smaller tank along side the diesel tank.
As opposed to the truck I'm in, which has a DPF filter as needs to perform a 'burn off' to clear it out by sitting stationary high idling at around 1800 rev's the system then squirts a bit of fuel in the red hot exhaust for 20 to 45 mins. However the filter now needs replacing at a cost of $3500. Some trucks filters are around $10000.

Speaking to my sister in Yorkshire her diesel Honda CRV has a similar filter which now needs replacing. The cost of which takes the shine off the benefit of lower fuel bills.
Something to bear in mind of what needs replacicing down the track when tempted by 'cheaper running costs'

Maybe cars will soon be running adblue to as there is a network already in place for it?

We just have to be careful to not mix up DPF (diesel particulate filter) with the SCR (selected Catalytic reduction/urea injection) and yes we are running both in Aust and will do for some time until we find a better way to target NOx.
The DPF is about removing the unburnt hydrocarbon from the exhaust and this is where regeneration cycles are used. If the catalyst in the exhaust doesnt get hot enough to incinerate the captured hydrocarbon under normal driving conditions, then a form of regen will occur. This is where exhaust gas temps need to be artificially increased to enable the burn to occur. This is with either dosing injections from the CR injectors or when CR isn't used dedicated dosing injectors in the manifold.
SCR is for targetting the nitros oxide emissions by adding the ammonia (from the Urea) into the catalyst. The ammonia catalytically reduces the NOx into water and nitrogen both harmless components.
We can and do use both systems in our euro 5 trucks in Aust and this isnt going to change for euro 6 as I think from memory, the increase to E6 has been more about the emissions defeat mechanisms rather than changes to the actual gas levels from E5.

Looks like fun

Another mock-up, but there may be something on the way...

I found out today from a friend in the motorcycle press that Yamaha quietly transferred the production of the XSR700 to the Saint-Quentin factory (where the XT is made) back in October, to be followed by two more models later in 2016.

Read into that what you will? It's most likely that the "two more models" are the MT-07 and the yet to be revealed MT-07 Tracer, but one of them might well turn out to be an XT-07/XT700/XT690...
