Cummins and Detroit went with EGR in 2003 and DPF/DEF with EGR in 2008.
CAT was in a transitional period in 2003-04 and went with ACERT technology in 2005. In 2008 they also went with DPF/DEF with ACERT.
CAT never had EGR and IMO the ACERT is less problematic.bayoustate Thanks this. -
ECM's: 1995-1999 (yes computer's are an emissions tool)
EGR: mid 2003
CAT Bridge engines: 2003-2004
CAT Accert: 2005
DPF: 2008
DEF: 2011Last edited: Aug 25, 2016
bayoustate Thanks this. -
There's also the 1994 emissions, the point when manufacturers began using the diesel oxidation catalyst.bayoustate Thanks this. -
What is a diesel oxidation catalyst and who used that? Don't think I have anything like that on my 95 and 99 Cummins.bayoustate Thanks this. -
DOC was a very coarse filter... now, it's typically a part of the DPF inlet. I believe Cummins began using them at least on light and medium duty applications in 94, though I gotta do a bit of digging to be entirely certain of the year.

EPA04 - EGR
EPA07 - DPF
EPA10 - DEF
GHG14 and GHG17 are just continuations of EPA10 with higher necessary NOX reduction.
This is when the stuff was mandated, as mentioned different companies tried different things before this.rank and bayoustate Thank this. -
Cat intake act valves are same thing as egr. .cat didn't want to be part of known egr because Detroit and cummins had been for years and had so many issues. So yes real world car motors have egr system. That's why if you tear one down that has had bad iav you will find Sut in intake fresh air systems. Also the motor that destroyed cay motors in the USA.
