DEF is treating products of combustion as I understand it, specifically oxides of nitrogen. No chemist or engineer, but seems like whatever is in diesel fuel that produces NOX in combustion would have to be removed from the fuel.
And on further reading, NOX formation seems to be related to high temperature combustion processes, which must be the major challenge in cleaning diesel exhaust.
The only way to eliminate the formation of NOx is to remove Nitrogen from the air!
Maybe if we all put it in our tires it would help!:R
Even though it's fairly new here, DEF has been in use in Europe for years.
Do you REALLY think the FEDS would allow companies to stop producing the stuff and make thousands of trucks non-runners??
Actually yes I could see that happening. If new technology came out making this crop of DEF emission vehicles comparatively dirty who knows what the government would do. They had the buyback program where they killed the engines so they could no longer be used. I would say the likelihood is very remote but on the other hand I would not be shocked either.
