First year for emissions?

[kad]

Question for our resident historians, what was the first year they started putting all the emissions cr@p on the Dodge/RAM diesels?

That depends on what you consider "all that crap"? It happened in phases (and don't quote me on exact dates)

Early 3rd gens 2002-2006 had a "in Cylinder" EGR event
2007-12 added a EGR valve as we know it today and a DPF
13+ was EGR, DPF, and DEF/SCR

It happened something like that but I'm sure an "expert" will have the exact answer, we have plenty of them on here Lol.

Sounds about right. I think starting in 03 model year they had cats. But no sensors no real monitored emissions. Late 07/first 6.7L had egr (blue something was a badge on the tailgate basically saying it had emissions).

Pre 07 offered 2 versions of the 5.9L. 12v and 24v. 12v 89-97 24v 98-07. 12v is mechanical and 24v is computer controlled.
So 5.9L cummins are desired and easy to modify. I think 06/07 5.9L were a little more computer controlled so you'll find more "modern" tuners for them but not 03-05. I think around late 97-02 5.9L cummins can be tuned, quadzilla I believe is the most popular and offers "custom" tuning. 94-97 are probably the most desired 5.9L. They are the "p pump" motors. Mostly mechanical and easily modified. 89-93 offered 2 versions of the 12v 5.9L VE pump. Non-intercooled and intercooled. 89-91 were Non-intercooled. The Non-intercooled you are limited on how much power you can make due to the fact you don't have a intercooler to help out. You can add one but you end up being limited by the VE injection pump.

1990 5.9L 12v Cummins W250

You can thank Ronald Reagan for killing the "muscle cars", he's the one that started all that crap.
Who'd of thought all these years later we'd have cars that have factory 500-700+hp, get good gas mileage if you stay out of it and have good emissions?
We're truly blessed!

It's amazing what they have done for sure. Now if they could just make the emission systems reliable that would be the icing on the cake and life would be good.

agreed.. if they could make the emissions crap reliable, and not kill the motor, it would be awesome

Wasn’t aware RR created the EPA. Yup, you guessed right, Nixon started the EPA.

I just saw your post and wondered if you could elaborate on this comment. I was unaware of any influence Reagan had on the auto industry.

Yeah - The Clean Air Act was passed way before Reagan's time

From what I remember, Reagan was for curbing the use of CFC's in an effort to slow the depletion of the ozone layer. I don't remember him pushing anything emission related. Muscle cars were primarily killed by a combination of gas prices and insurance rates. Followed quickly by heavy emissions standards. All of which happened before Reagan was elected president.

I'm all for posting about history. I just want to caution people not to make this discussion political. It's a slippery slope.

Didn't the end of leaded gasoline come about in the Reagan years? That's the only thing vaguely related I can think of, and I wouldn't swear I'm remembering that correctly.

That's a good question. The EPA first started phasing out leaded gas in the early 70's. So that would have been before Reagan as well. I don't remember when it was fully phased out in the US though.

Edit: After a quick search it looks like leaded gas wasn't banned in the US for passenger cars until 1996. It took from 1973-ish till 1996 for the conversion to happen fully.

It started in the 70s. My 1970 LTD wanted leaded fuel, my brother's 1972 Gran Torino did not. However you could still buy leaded gas at the pumps through the 80s. In the mid 90s, I distinctly remember having to buy additive to keep valve clatter down.

Quick google:

E.P.A. ORDERS 90 PERCENT CUT IN LEAD CONTENT OF GASOLINE BY 1986 (Published 1985)

www.nytimes.com

The Environmental Protection Agency said today that it was considering a total ban on leaded gasoline by 1988. It issued final rules for removing 90 percent of the lead currently in automobile fuel by the end of this year.

The agency said last year that it was contemplating a flat prohibition on lead in gasoline by 1992.

Lee M. Thomas, Administrator of the environmental agency, said that an accelerated schedule for barring all lead in gasoline was being considered in large part because of new information about the adverse effects on human health of lead in the air. In particular, he noted that new studies suggest that lead from gasoline is a significant cause of high blood pressure among adults.

Mr. Thomas said that new data the agency is receiving indicate that lead may not be essential as a lubricant to protect engine valves of older cars and trucks. The contention that lead is needed as a lubricant has been used to argue against a total ban.

Schedule for Reductions

Last year, the agency proposed the first version of the rule that will reguire a sharp reduction in the lead content of gasoline this year. The rule requires that lead content of gasoline, now permitted to be a maximum of 1.1 grams per gallon, be reduced to 0.5 grams per gallon by July 1 and to 0.1 grams per gallon by Jan. 1, 1986.

My 66 Impala had an air injector, which was a form of emissions controls. A bit before Reagan

My '66 Chevelle had nothing like that. I've never heard of such a thing. Can you give a little more information about this?

I *think* it was a California only thing in 1966, but perhaps HarryS can say more. Chevrolet called it an "air injection reactor."

*edit*
https://www.sae.org/publications/technical-papers/content/660108/ is the first hit on Google if you search "Chevrolet Air Injection Reactor". It seems to imply it was only CA. I remember a few other CA-only vehicle configurations, even through the malaise era. Certain Corvettes were 305 only in CA but 350 everywhere else, for example.
