Moving from Tier 3 to Tier 4i requirements brought two technologies to the forefront: Selective Catalytic Reduction (SCR) and Exhaust Gas Recirculation (EGR). Some say they can get by with super high injection pressures and precise controls. KX057-5. It turns out that Americans truly do adapt and overcome. You may also be wondering if there is a way to delete the DEF system because it can be expensive to maintain and you may not need it in your area. Then the exhaust travels to a Diesel Oxidation Catalyst (DOC) and diesel particulate filter (DPF) where the DOC further cleans particulate matter with increased heat while the DPF collects the remaining soot.

And either Cummins or Jd has one with no egr, but I can't remember which one. For example it would take over two years a constant rate of 125 degrees F for the DPF to turn into ammonia and evaporate. Far as I know only us (I work for Case and Case IH ) have the patent on SCR only technology. The result is that NOx is too high. Almost all diesel-powered trucks built since 2010 are equipped with Selective Catalytic Reduction (SCR) that utilizes Diesel Exhaust Fluid (DEF) to help reduce the production of Nitrogen oxide (NOx). Lastly, when DPF filters require servicing the removal of ash remember, the EPA and California Air Resources Board (CARB) have labeled the residue a hazardous waste. It may not display this or other websites correctly. Read about Snow Removal: What Implement to Best Handle Winter.
