1971 CEC Combined Emission Control

[Kevin G.]

Hi Folks,

According to this small service communication pamphlet I collected a few years ago, it states;

"This booklet contains a complete reprint of the sound slidefilm, 1971 CEC."

My questions are, has anyone ever seen this slidefilm?
Does anyone have an original slidefilm?

Here are a few pages. If anyone has information concerning the slidefilm I'd like to obtain a copy!

I think this may be the service departments missing/added information Jack Humphrey mentions in his CEC write up?

There were a few that weren't aware this booklet existed, so I thought I'd share it here. Excuse the cell phone pictures....A better copy can be made available.

Re: 1971 CEC Combined Emission Control

I am pretty sure Ii have it (the slide film version), but I put all those old 35mm slide films in cold storage and I am reluctant to get them out. With some there is a phonograph disk, later ones had a cassette, designed to play in DuKane projectors. Some of the new model year car introductions for the sales people are extremely interesting as well. The disk or cassette had a tone that advanced the slide film in the projector. That sort of electro-mechanical equipment is now ready for the history museums. I should dig all that out and give it to the NCM. I doubt it will do anyone any good where it is.

You would be doing many people a service to make good scans and host them on-line for those in need.

Hi Kevin. If you do have the time and the resources I would very much like to download a copy of that booklet.

Kevin,

I can scan it and put it in our June newsletter!

Hi Terry,
Now you have my attention! Very interesting.

If you could find your way to the storage area and retrieve this slide film, I'd love to take this topic a step further.
While preparing for my PV, I was educated on the CEC by our local hands on expert Tim Raisner. With his help, we were able to confirm and correct my systems operation. Just a part of the 71 that I found very interesting.
I've since began to compile every piece of information possible I could find, with hopes of creating a complete write up with a video of car running through the process.

Looks like a lot of good can come from this one! Let me put something nice together.

PM your email addy.

Kevin,

Hi Tom,

We'll talk!

Re: 1971 CEC Combined Emission Control

If you included in your proposed presentation both a BB and small block, manual and automatic transmissions you would have one chapter of a book that if it started with 1970 could continue much farther into the 1970s. I know 1974 had a TCS system that was based, IIRC, solely on engine temperature. I don't know if that was the end or if variations on that system continued. There is a Chevrolet Emissions book that contains a lot of that information, but it is confusing because like the Chassis Service Manual and the booklet you have, it is often difficult to separate the Corvette system details from those of the other Chevrolet car lines.

My 1970's TCS solenoid has not been used since SEP 1970. Better gas mileage in the city and engine cooling with full time vacuum advance.

Terry,

At this time my main concern is with the 71 CEC system. There is a very good chance I'll be comparing it to the 70/72 TCS system, mainly because I have the 72 here to use as an example. It's the infancy of Corvette emission controls that peaks my interest, so far. It's taken me some time to completely grasp the 71 system, so I'll go one step at a time!

I realize these types of requests can be more than just opening a draw or book sitting next to you. Many times I receive request for pictures or information and as tired as I usually am after work I try to accommodate.

This is something that I have been wanting to work on for some time, to hopefully take some of the mystery away and maybe make understanding the system a little easier for others.

I'd love to take a peak in that cold storage locker!

Re: 1971 CEC Combined Emission Control

You do realize that those are 35mm film strips that are next to un-useable without the working projector to put them on a screen for people to view? They might be able to be viewed in a microfilm reader, but those are a vanishing technology also. Could they be converted to digital technology? I think so, but that would not be without substantial cost and best born by a large institution rather than individual researchers.

So just like the old 5-inch floppy disks or the more recent 3.5-inch so called floppy disks, what is one to do with this old technology? And yes I know there were earlier 8 or so inch floppy disks that also beg the question.

Re: 1971 CEC Combined Emission Control

Terry,

You're aSSuming I don't have the resources to view or copy slide films. I am a serious hoarder, surely I have just the thing! With a vintage screen!

If anyone could help me with an original set of films I'd be willing to go the extra mile to complete this helpful task?

Thanks

That is not the way you do it.

You are assUming that there is a difference in the booklet you have and the film strip/audio. I believe what you will find is the film strip contains the pictures and the audio is the text from the booklet you have. So the AV material is simply another media of what you have. At least that was what I found years ago with other technical material.

Re: 1971 CEC Combined Emission Control

Alan, Thank you kindly for the encouragement! I will be happy to have your help and knowledge. More so your elegant communication skills!

If you remember we worked as a team judging operations, I think more than once. It was my pleasure to help the owners learn how things are meant to operate. I do agree that many have trouble understanding these systems.

This project is something I've wanted to create for some time now as as said earlier, and I don't expect to finish over night. A little effort to make it as you say one step further, is the goal.

Again thank you for understanding the need and the gracious offer to help!

Terry,

The only assumption I think I made was that I would find help here?
Most research done here started by one man, not a huge "Microsoft Corp" or "Institution"?

Terry this is the second time that I have stumbled across something really neat, that I feel has importance to others. In which you have left me with the feeling that I am not worthy of having. If you recall my article from the 1955 memo. We, with NCRS numbers higher than yours do have interests in the knowledge you have learned and or locked up in cold storage. Without these original sources, where do we turn?

If you review the posts above I made three polite attempts asking for your help with this slide film. As I read, there was no definitive answer, your reluctance indicated a negative? However, you did reply with information.

A side from floppy disks and assumptions, I will continue this project and to search for a copy of this original slide film, that I hope matches my booklet word for word, as mentioned in my OP.

My motive is to help reduce some of the mystery many still have with early emission controls. With the advancements in today's technology surely we can come up with something a little better than the "BING,NEXT SLIDE PLEASE! Now there's a memory from the past. Something as unimportant as the "BING", holds importance to me and I would think future readers?

So, what you know, is what we need to know, but without you knowing, we have to know?
Easier?

Re: 1971 CEC Combined Emission Control

Lots of guys pot these old tech filmstrips on youtube. Search SuperBeeRegistry on youtube, he has a bunch of old Mopar ones posted. The technology exists.

I am sorry you think my sharing what I know is throwing cold water on your ideas. I don't understand how you can come to that conclusion, but i have the solution.
