Sorry, but no, it didn't do that. There is no barometric capsule device on these systems at all. Never-the-less, they were, and still are a brilliant design in the context of the times.
This systems biggest enemy was ignorance. Same with most carburetors. People tinkered around on these units and threw them away back in the day. It was way ahead of its time.
Actually the Rochester Quadrajet is more complex to tune than any of the FI 's from 57 to 65. My brother had a 62 fi on a 327 350 horse hydraulic lifter powertrain. 2 screws on the fuel meter and 2 screws on the air meter had to be balanced using a manifold pressure gauge for optimum performance. Not hard to tune just a little patience and time.
Not many knew how to work on them so they put carburetors on them and threw them away .. I am sure that if anyone bothers to purchase a GM Service manual . They would be easy to tune.. Stock they ran too lean.. adjust it a tad richer for better response and higher horse power.. Just like any modern car engine today to meet emissions standards it is running too lean.. Also it was a $600 option on a $2,200 car.. Today you can buy a modern system that looks like the old Rochester..
@@mikeskidmore6754 By todays standards they are easy enough to tune. But back then fuel injection was a completely new concept. The biggest problem was guys didn't understand the concept and customers didn't want to pay them to tinker. So in the secondhand market most got shelved like you said.
I have that on my 1964 Corvette. People talked crap about them. I LOVE IT. Change the damn Diaphragm seal when it’s worn out. People don’t like things when stupidity seeks in🏁🏁😎
"Today's carburetor is a triumph of engineering research and development with outstanding research and development." I love it. Just sheer awesome quote really shows you the optimism and "science can do dis" attitude at the time.
Just imagine if they had figured out how to time it like sequential injection, i suppose you could drive something like that off the camshaft? It would have halved the fuel consumption against a dual quad car allong with way more than 1hp per cube inch😮
I am so happy these films are still around. I hope those viewing these today don't think the picture was as bad as we see today. Film was/is an incredible medium and done properly is much better than digital. Unfortunately film was celluloid (organic) and unless properly cared for tended to degrade.
Back in the day that system was often removed and relegated to a shelf, replaced with a carb. Not many mechanics knew how to work on the system. In 1958 Pontiac used the exact same system, making them extremely rare. I knew a fellow that had two Pontiac systems on a shelf. It was not a timed injection with a single squirt per revolution, it sprayed constantly into all the cylinders. VW used exactly the same concept, they probably bought the system from GM or Bendix.
Rochester and Bendix are / were GM brands. It's interesting that Bendix sold their Electrojector only to Chrysler, and it was a total failure. It got sold to Bosch, who finally produced their electronic fuel injection in 1967 for a VW
@@paulkirkland1535 I posted about that on Jay Leno's video on the injected Chrysler 300D restored by Per Blyxt: There is a car with its original Bendix Electrojector system working. It's a DeSoto, virtually the same car as the Chrysler 300D, here: www.allpar.com/cars/desoto/electrojector.html The owner got the 'computer' working by replacing transistors and capacitors with modern faster-acting equivalents.

They were common in the 50s; they were moved in the early 60s after safety advocates pointed out how dangerous they were on the dash. Also, mirrors were screwed into position; there were no breakaway mounts such as we have now.
RaymoAZ feedaboo The dash mount rearview mirror only appeared on on a few early hardtops. It was eliminated after about one month of production due to excessive vibration.
You're spoiled to today's smooth digital audio. In this clip both audio and video came from film that was produced over 55 years ago, and shown many times on projectors. Also, film deteriorates.
@Stuurm yea, this was mechanical fuel injection which, while more efficient than carburetors, was less effective than electronic fuel injective, which is more responsive, is able to adjust throttle response more accurately, and can provide a better, cleaner burn. Electronic Fuel injection was very primitive in the '50's-'70's because the wires/electronic control unit were very weak and susceptible to engine noise/heat. Mechanical fuel injection had linkage problems etc.
It is interesting how the rochester fuel injection even compensated for altitude like modern computer fuel injection

How cool it is, to have these little snippits of the past, and to see the early beginnings of something that we expect on every car today.

With fuel injection, you can get 9 MPG instead of 8 MPG!
I still have a flight engineer guy riding in my car. Are you telling me he's obsolete now?
Strange to see a 1957 Chevy with a 1957 Dodge mirror?

Does this have choppy audio for everyone else, or just me?
No..... It mu.. be on..y your... end.
Enjoy these old videos. Thanks for the post!

better than 4k? come on man.

A ;57 Chevy, fuel injected, a 2 door hardtop Bel Air, with only 600 original miles on it...I'LL TAKE IT!!!

The rear view mirror on my 1960 Chevy was an EXTRA, for $5. Electric wipers were $15 extra.
chevy 327 fuli was the best cheer ever did.

Zoro Arkas Duntov and Smokey Yunick helped design it
These fuel injections were a total nightmare to mechanics and still to this day is tricky to work on

Excellent stuff
As So gwass-hoppah, I do not ever remember seeing on either.
The film shows 1957 Chevys
Wow-I did not kow that the '57 had a dash mount rear view mirror. I wonder if this is a sign of a fuel injection model?
mainly on the 57 4 door hardtops yes i have had one neat change from the norm. very rare thou.
Ahhhhhh the F101 Voodoo
Good Old Days
look again-it was 60 miles!. I'll be havin' one too!!
were there problems with this system? why did it not last into the 70s/80s
Stuurm it was expensive
A $500 option. It was around until the big block came out. That was a much cheaper option for horse power
audio kept cutting out for a split second
That was a 10 minute explanation of a 2 minute topic, my god i almost fell asleep.
some say to this day he's still sleeping
