So what's the deal with all the "new" emission technologies. I have done breif reading and research on it and come up with some general types: SCR DOC PMC and DPF, I have yet to completely understand each and every type. Just a little curious about all these tier 4 final engines. Anyone know what each acronym stands for and what they do in terms of fuel efficiency and how they may affect longevity and performance of the engine?
