Emission control on Chargers

[69bronzeT5]

I'm doing a project for Auto Shop. Could you guys tell me everything you know about emission control on Chargers? Post pics too if you have 'em. Thanks!

Emissions?Charger? Never thought I would hear those 2 words in a sentence..

[WingCharger]

Lucky. My school doesnt have Auto Shop.

But, I know Dusters didnt get Catalytic converters until, uh... '74 I think. But, late third gens may have had emissions controls. I know California model 70-71 HEMI engines did too...so thats all I got.

My school's auto shop is decent....kinda cold sometimes, decent tools but really crappy cars

You have to go the Career Center here to get auto. They have half day courses, (Half day Career Center, half day High School) but Auto SHop aint one of them.

My school is like wingcharger's. All emission controls I know would be the PCV, charcoal canister, and maybe vacuum advance.

You maybe need to be a little more specific Bronzy.  Do you mean all Chargers or a particular year?  Emission controls were under a yearly transition from the late 60's to the present day.

Particularly '69s.

I don't think there were any Federal Emission Standards on that year engines....PCV valve system was on all, some had a "Clean Air Package" which was a hose from the oil filler cap to the air cleaner. (see pic below)

Some California cars had a distributor NOX advance valve...that was a separate advance valve placed between the carb and the distributor.....had 3 vac lines to it....one to the carb, one to the dist, and one to manifold vacuum. Purpose was to keep vacuum advance engauged in the distributor for a while longer on deceleration, to reduce the NOX emissions....I don't have a picture of that part...it was a green canister that was bolted to the intake with 1 bolt...I have two of them here, but not on a car. Mainly were used on slant 6 engines.

Some engines had a distributor vacuum advance pod with 2 hoses attached, one went to the ported nipple on the carb, the other went to intake vacuum to retard timing at idle....this was used to reduce Hydrocarbons at idle.

That's all I can think of for '69.....EGR was not used yet, neither were air pumps for the exhaust manifolds.

I'm sure somebody else will chime in and add to my list

[69bronzeT5]

How important were the exhaust manifolds when it came to emissions? What was done to them to help emission control? Particularly '73 318 models (I have a set of those manifolds sitting around I can bring into class).

[A383Wing]

Got a picture?

[69bronzeT5]

Of the manifolds? No sorry

[A383Wing]

OK...short version here....on air pump equipped cars....air was pumped into the exhaust manifolds to complete the burning of the un-burnt gases to reduce HC's (hydrocarbons). Some cars plumbed it into the exhaust manifolds, some like Ford plumbed it into the rear of the cylinder heads. Chevy had it into the exhaust manifolds. Looked like a big "fork" into the top of the manifold. It's been a long time since I have seen how Ma Mopar did it....

Damn.....I ferget now....

Looked like a big "fork" into the top of the manifold.

Is that what it looked like on the Mopar side?

[A383Wing]

Again...I don't remember.....

Ah okay. Well, thanks for all the help! I'm just finishing up my project and heading to bed.
