EPA approves the use of SCR devices!

I edited out the pictures and replaced it with a direct link.

what in the hell are SCR devices? I can't tell from the link.

Selective catalytic reduction (SCR), a process where a gaseous or liquid reductant (most commonly ammonia or urea) is added to the exhaust gas stream and is absorbed onto a catalyst. The reductant reacts with NOx in the exhaust gas to form H2O (water vapor) and N2 (nitrogen gas).

Cool! Your pic was very helpful. I wonder if this works on biodiesel? Supposedly Texas LED fopund an additive to biodiesel which reduces NOX without removing the good qualities of biodiesel including lubricity!

If I understand this right, it means adding a urinal to the trunk to reduce emissions? Cool.

The composition of the output looks remarkably like urea-sourced, nitrogen fertilizer.

Does this mean if you run your SCR tank dry you get a ticket? Also I take it this additive isn't going to be free.

We have had these things over here in U.K for a while....
TheAdditive 'Tank' is part of the vehicle (Pretty obvious...!) But it is not a User-servicable item. It is a 'sealed' vessel and the fluid is admitted in tiny quantities, metered by the engine-management. The expected life of an additive package is around 3 years. It will cost around 300 stirling (600 bux) to replace.... The vehicle goes into 'Limp-Mode' when the additive is all used up, and indicates that a new 'cartridge' is needed. most places, ( Main-Stealers) will replace the Cat at the same time at an extra charge.... There are two common type additives used in Europe. The 'Urea' based one, and a Cereum based type. Not sure of the techinical differences, but apparently one type injects it into the fuel-tank whenever the fuel cap is opened and re-closed and the other into the exhaust system up-stream of the Cat. One Trade-name of the additive here is 'Adblue' but which type this is Im not sure....

Unfortunately, the story for BioDiesel and these new emission technologies isnt so good. There have been instances where the engine-management has been confused by bioDiesel in these systems and with the other Particulate-trap type, has caused polymerisation of the engine-oil and engine destruction due to the way these things periodically 'clean' themselves.... They are 'programmed' to periodically inject fuel on the Exhaust-stroke, where quite a lot of BioDiesel will find its way into the lube-oil. With std. diesel this isnt an issue as it will evap out through the Crankcase ventilation back into the inlet-tract. BioDiesel does NOT evap out of lube-oil and builds up to critical mass..... Some makers such as Volkswagen Prohibit The Use Of BioDiesel in their cars fitted with these technologies, Unless specially Ordered from Germany as a BioDiesel compliant vehicle. It is NOT a main Stealer modification allegedly.....
