The more powerful diesels for automobile use, like the hot Mercedes system, are apparently very hard to make meet US pollution standards. The last time I paid any attention to this car, it was necessary to inject liquid urea to make them pass. This would be a bit of an annoyance, I would think.
Urea injection is what Mercedes and other Diesel engines use to meet European, Japan, Australia etc pollution standards. And they have been doing it for some time. I think it is just this last year that US NOX emission standards for diesels have caught up with the rest of the world.
Urea injection is in the new GMC diesel pickups.. Sierra 3500HD

The diesels don't meet the particle emmisions requirment . The Urea nonsense is another costly but useless thing required by the EPA. The usual thing is to put water in the tank and in cold weather put water with alcohol.
