| In an effort to clean up emissions, manufacturer's of diesel engines have developed a system that reduces or eliminates nitrogen oxides. That system commonly consists of a urea tank and injection system which injects urea into the exhaust before it gets to the catalytic converter which will reduce NOX. NOX is considered hazardous to the environment. This is basically the same type of system that power plants use to to reduce NOX emissions. However, power plants use a lot more urea to get the same desired results.
The fertilizer plant I work for actually supplies quite a bit of liquid urea to just such a use.
Expect all newer diesels to have this system in the future. The problem will be, where do you go to fill your urea tank and what analysis it will be depending on the weather. Get your diesel pickup now. That is why I purchased an '06 Dodge w/ Cummins which doesn't have all the B.S. I just described. I believe 2009 is the absolute deadline for diesel compliance regarding NOX redux.
