The racket that you have undoubtedly heard when a diesel Ram pulls up next to you at a red light has also been cut in half.

This system allows particulate filters and NOx catalysts to be added to existed tractor trailer engines. It can reduce particulates by eighty-five percent and nitrogen oxides by twenty-five percent.
