Wisconsin | As has been said several times, HPCR is so much cleaner that you won't notice the difference compared to a modern HPCR for the military or export, like you would compared to something from the early 80's, which were driving around into the 90's and 2000's. As CMayer said, the two emissions are NOX and Particulate, you can see some of the particulate, but not all of it, and not the most dangerous. You can't see NOx at all, so what you see is not a good measure of pollutants. By the late 90's, gas vehicles were so clean that diesels produced a massively disproportionate amount of highway pollution, and still do to a lesser extent. | |
