Now that all new vehicles sold after September have to be EU6 compliant and it effects diesels more than petrol engines how are Land Rover going to make their engines acceptable. All VW and Skoda engines are having an item called AdBlue sprayed into the exhaust system via an extra tank. Peugot and others have something similar. Anybody know how Land Rover are doing it, or are they just going to build new engines.
 
have to go adblue, no big deal really. Have had to for a few years here, in cars/trucks and farm and construction equipment
 
and what is it? Did a search and no answer

It is a urea based additive which burns in an after burner in the exhaust and cleans up the dirty particulates,
 
It's not like trucks where you have to keep filling it up every few tanks. The idea is that it's a service item to refill the reservoir.

Personally, I see it as a stopgap measure- I think it's Mazda who have reengineered their engines to emit less nitrous oxides and so meet the regulations without the need for adblue.

2.5 gallons does about 800 miles. separate tank from diesel

There are two ways of reducing NOx, and I think ADBlue or any post burn approach is the wrong way around as your curing the result not the cause.

Carbon Monoxide and NOx are created when you burn a fuel fast and at high temp. In the past on Diesel engine emission controls were basically just EGR valves, these were used to feed exhaust gas back into the inlet to reduce the burn temp during combustion.

EGR valves have their own issues, first that's un filtered corrosive exhaust gasses your feeding back into your engine. Second this type of system can only work at idle or overrun on a turbo diesel, any other time the inlet manifold is at higher pressure than the exhaust. So when your pulling hard and the turbo is spun up to pressure there is no emissive controls, but this is when you need them most.

For me I believe the best approach is water methanol, this has been done for years on petrol, diesel, and jet engines. This works in two ways, both reducing NOx, and CO. First the Methanol improves the burn efficiency and this also has a result of giving extra power. Second the water cools the burn therefore slowing it down and reduces the CO and NOx, it also cools the intake air giving higher compression, again aiding efficient burn and producing more power.

With Water Meth, you do not need an EGR valve that has been proven to reduce engine life, you do not need to add chemicals to the exhaust, and you get more power for less emissions. I can't work out why this approach is not adopted main stream?

I might suggest that its the same story as sentinel steam wagons, or the everlasting oil filter.

IMHO, both were shut down to make sure big business could keep taking money off folk.

If you can get more power out of a given amount of fuel, using an additive which is cheaper to produce than refined hydrocarbons, then the rather large oil companies may, or may not, have a vested interest in "going in a different direction", if you get my drift?:D

+1. You forgot aircraft, ships and space rockets, cars produce a tiny percentage of total pollution.
