Ford 7.3L gas power numbers

"In fact, the US's NOx limit is 30 times lower than the EU emissions, and the CO and CO2 limits in the US are much higher than EU. This is why EU diesels do not have to have EGR's like we do in the US which allows them to not only have higher power output, but also better efficiency."

I have found that most people don't seem to be able to understand that just because a lot of something is bad doesn't mean that even a little bit is bad. Heck, some people have died from drinking too much water. Some Americans now suffer from lack of vitamin D and related symptoms because too much sunlight is bad. Moderation is not in our vocabulary anymore. I have long felt that the best way to reduce GHG is to back off on some of the other rules that hurt the efficiency of all ICE engines.

I agree.

Another thing that a lot of people don't understand is that the bureaucrat that thought up the NOx limit for the diesel truck makes to meet, did so without knowing what it would take to achieve such numbers. These numbers are set in stone years before implementation, and manufacturers have to figure out how to meet them. So when they say that diesels have to go from a NOx of 1.2 g/hp-h to .02 g/hp-h, they don't know that they are doing it at the expense of efficiency of all diesels, more oil has to be converter to fuel since these trucks are not as efficient, more pollution from making DEF, more pollution from making DEF jugs, more pollution from DEF plants, more pollution from fleets that deliver DEF, and so on.

Also, just as with most government rules, once they are set in stone, there is no going back or reviewing to verify that the new limits are better for the environment when all things the manufacturers had to do in order to meet these numbers years later are accounted for.
