Do it yourselfers do weird things...
I had a sort of reed valve from exhaust to inlet manifold, and it coked up about 200,000 km in, and it was not available as a replacement.
So I closed it with a piece of gasket sheet, no performance issues, the car was on Auto LPG, not much emissions issues.

I've managed to dig out " automotive fuel injection systems " ( Jan P. Norbye ) - a mine of information on the development of fuel injection ). Apparently the Alfa used a " Spica " system that used ( as did subsequent mechanical systems ) a 3d cam, a cone that not only slid axially, but also rotated. Someone previously mentioned an aircraft V8, possibly by Antoinette, I don't think they used it on their arrow 3 cylinder, but " those magnificent men in their flying machines " is currently airing ( I'd LOVE to know how they filmed that ), so I'll keep a look out. I think Antoinette used a ring of small hole uncovered by the piston ( yes, on four strokes ) to help release exhaust pressure, and admit some cool air, at the end of the induction stroke.
It wasn't a diesel, I mentioned it because it had the mechanical direct injection.

There's a book but not cheap:

One of my favorite films as a kid. I wanted to be Pierre Dubois - which led me to flying ultralights.
That link is flaky; it might not be public.
Go to this page and scroll 1/4 down to the little picture of an airplane.

This version has less about the movie reproduction but a lot about the original.
Having owned and driven a few carbureted vehicles in the past, I enjoy fuel injected vehicles for a few reasons. However, I also tuned engines with different ignition advance curves, by modifying the flywheights in the mechanical advance system as well as the changing the vacuum advance system. On my last Quadrajet carb, I removed the choke horn completely, blending the flange with die grinders. I would experiment with different jets, secondary metering rods and hangers scrounged from the junkyard. With an oxygen sensor bung and an Autometer A/F gauge as well as a vacuum gauge, I had the last 5.7L small block chevy I owned running quite well with very respectable fuel economy. 1 3/4" primary headers with 3" collectors and a free flowing dual 2 1/4" exhaust helped out as did the Edelbrock Performer RPM Q-jet specific intake manifold.
In an otherwise stock G-body, the combo was good for 13's in the 1/4 with the stock peg leg diff. Not too shabby with limited traction.
Stock anti-abuse algorithms and lame tuning in some modern vehicles are a pain in the ****. Floor it from a dead stop? That's ok, the ECU pulls out 30 degrees of ignition timing, in order to 'protect' their driveline warranty, not to mention satisfy the eco police. With premium fuel on a good tune, the same vehicle is a beast with no other changes. Modern fuel injected engines with stock ECU's and manual transmissions suffer greatly from 'rev hang' which is a real pain if you want to shift quickly.
Thanks for the link! It's hard to believe only two years elapsed between the latest of Santos-Dumont's aircraft shown in that volume and the Deperdussin racer of 1912. The latter looks relatively modern by comparison.
The Deperdussin was made to race. It ran a 14-cylinder engine at 160HP(?) and maybe 6 times the weight. 125-130MPH. Very much in the mainstream of fast flight. (That wacko fuselage construction has come back into fashion a few times until Aluminum got good.)
The Demoiselle was Santos-Dumont's personal ultralight (before that was a thing). 2-cylinder engine had maybe 20HP. Flew 35-50MPH, if the pilot were petite. This is the guy who flew a powered balloon through Paris to a cafe. While he did register for a prize (he failed), IMHO it was basically for fun. Santos-Dumont was nobody's copycat.
