This is going to be interesting
Diesel emissions to a basic standard, have been in place for a long time , however there is nothing to stop each state from raising the bar to a higher level of emission control standards such as California and New York, for example.
The word document of HK although he said , I was not able to get the entire table to stick is basically correct.
Two different warranty tables! are for class of vehicle H/P and weight/ splitting off into exempted or extended time frames under the cafe' agreements set by the Feds
Manufactures pay a tax impost, to have the vehicles on the road.
5.3 and 52.1.E I E is for fuel ratings,have been set to a 1999 meeting that predates back to 1996! first implemented under the bin 11 Euro 3 mandates for 2002 in Europe, 2003 for the US under the Californian clean air act for emissions, oddly enough its for H/D under ground Diesel units where the said standards were to be implemented,
1999-2001
In short a preferred unenforcible mandate has been set
manufactures have the cat SCR on line ,but the fuel is not ready until 2010 in all US states there is too much sulfur and mineral content in the fuel, which can damage the systems.
Shell and BP are at least putting additives into the fuels. however the question is how effective will it be ! when it reaches the final distribution points of the outlet pumps?. other manufactures at refineries don't even have a Hydro cracking unit in place to refine the fuels ,
Chrysler Jeep has the EPA in court again forcing an issue of standards between states, and this has an immediate impact on the DPF and other gas particulate filters as well, GM is also taking the EPA to court over a similar issue in California and NY.

In effect the EPA has a mandate for ULSD For July 2006 , Manufactures have the cats on the vehicle, but the fuel is not readily available to the motorists on the smaller vehicles simular to the
Jeep that need it most, where! Quote the ULSD fuels for 15ppm and the sulfur content is being said not to exceed 500 parts per million The Standard is set at 300 parts not to exceed 500 part per million November 2006 USLD was being sent from California into Canada,where it had exceeded eight hundred parts per million and the fuel rating was 18+ PPM.Mercedes-Benz with drew the sale of the R Class Diesel vehicles which already have the DPF unit installed.
Who do you blame the vehicle manufacture! The EPA! Or the Feds? this is going to cause problems for quite some time.
2004-2005-2006 where agreements in principle to emission controls and the clean air act, to this day have not been submitted for review to be presented to both senate and Congress to pass as to the amendments being approved for certification. very complicated
