Can you replace a carburetor with a fuel injector?

You are certainly teaching that younger generation a very very important skill set that will never ever be useless. Fabrication is a field that is extremely valuable to have.

Great experiment, good job guys! Of course you really need to increase the 'ON' time of the injector during acceleration and reduce it during idle. Without any way to do that, the injector will always provide too much fuel at idle (rich) and way too lean at high RPMs. Keeping with a mechanical setup, you can improve this with a fuel pressure regulator with a vacuum port (this responds to engine vacuum to adjust pressure). At idle the throttle plate is mostly closed to give high manifold vacuum, this will connect to the fuel pressure regulator and responds by lowering the fuel pressure. Given the injector is pulsed the same amount, but with less fuel pressure, the result will help correct the rich condition during idle. During higher RPMs, of course the open throttle plate will reduce engine manifold vacuum to almost zero and the fuel pressure regulator will respond by increasing the fuel pressure. Again, assuming the injector pulse width is constant, by increasing the fuel pressure during acceleration will cause an increased fuel flow and help correct for a lean condition at this time...

I hope they don't stop broadcasting your channel! Your content is amazing!! Much love from the USA.

No problem, we used to call them single point injection systems. You can even regulate the fuel flow mechanically.

Try adding a vacuum reference from the inlet manifold to the fuel pressure regulator to increase fuel pressure as you open the throttle.

your injector pulse is controlled by the distrbutor, so the injector is open the same amount of time for each rotation.
so it's rich at idle, and lean at speed.
only variation you can really do is pressure.
vary it by speed, and you should be able to control mixture %.

I like this sort of "Mad Max" type thing... you never know if the situation might call for a crazy/simple solution.
Years ago I put a turbo on my car (a car that is rarely if ever turbo charged) and couldn't replace the injectors to get more fuel but I had not considered at the time adding a 5th auxiliary injector.
It was actually fairly common practice on cars with the same engine but I wasn't aware.

No politics, just the best experiments you could imagine. Amazing videos and narration.

This is basically Throttle-body Injection (TBI); some early 90s cars had this for a few years.

[dadsgametime]

You can tell you were suffering from all that atomized fuel. Way to be dedicated.👍 Best wishes from the USA. Loving your content for years now.

What I would like to see is whether you can run an ordinary standard engine on hydrogen.Otherwise a great channel, and keep up the fun content. Greetings from the Netherlands.

[jorgefernandez-mvhu]

That was pretty cool. You can get rid of the switch by putting in a relay so when you shut the key off it cuts the power to the injector. Great video.

[MichaelThomas-wbxu]

The Chevy 283 CI had a window in the distributor cap so you could adjust the point gap (dwell) while the engine was running, that would have worked well for you! You sure have a great crew, thanks for all you do!

[bobelaviador]

I own a Lada Niva 2001, with a Rochester TBI model 700, mono injector equipped. No complaints

[petermarios]

Great show as always, I would like to thank the commentator for all your work without you i wouldn't understand a word. Thank you so much and keep up the great work

In 1988 ford autralia did this for the EA falcon and called it CPI (centerpoint injection). It was 2 fuel injectors in the center of a throttle body. It wasnt terrible but also no great. It was used until 1992 and succeeded by MPI in the EB falcon.
You wont get it running spot on without a computer to change the injector pulse so its going be fine at idle and lean out at revs or flood at idle and be fine in the revs. The points are consistant and when you rev, the points contact is shorter so injector will have shorter pulse when it needs to have longer.
Basically, find a method to increase the injector pulse time the faster the engine revs.

This guy deserves WAYYY more Subscribers guys lol this guy has been at stuff like this for a long time now!

[googacct]

Very creative. I like the window you added to be able to see the fuel going into the engine. I also found your method of attaching the distributor to the overhead cam very interesting. It makes me wonder if you could take a car with an ECM and downconvert to use a distributor and carbureteur. .

At low RPM the distributor close for more mS the break points, at higher RPM is less mS per revolution.
That's why the engine is lean at high RPM (less mS for the injector less fuel) but very rich at idle
