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.

[@ecaparts]

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...

[@blackterminal]

[@inmyopinion6836]

Do you think my idea would solve your issues ? Big Dan 1 second ago Great video. I wonder if an injector would work through a Mikuni carburetor.

[@TestECull]

@Byw That's only because mechanical anything is a bad word these days and we've been dealing with computerized cars for over 30 years. Doesn't change what words mean. TBI is TBI regardless of whether the fuel injection is controlled by a computer, some clever valving, or hacked out of an old points distributor by a bunch of half-drunk russians in a back alley workshop. Your engine is MPI if it has fuel injectors at multiple points along the intake path. MPI is just multi-point injection. It's not CMPI or EMPI, it's just MPI. Multi-Point Injection. Diesel engines going back over a hundred years have MPI on them; any diesel engine with more than one cylinder will have MPI regardless of its age by virtue of how diesel engines function. Even some TBI systems are also MPI; GM had a habit of putting 8 injectors on one throttle body for their V8s in the early 90s before they finally gave up on TBI entirely and put the injectors at the intake ports.

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 %.

[@FrankFactor]

This is exactly the issue. Injector pulse width or pressure needs to be changed with engine speed.

[@scattkiwiman]

[@DUKE_of_RAMBLE]

Congratulations on creating a paradox! The engine needs fuel and air to run (generate RPMs)... The injector is hooked up where it only pulses ON (opens) every time the crank (well, cam) makes a full revolution. To increase the RPM, you need more air and fuel, on an upward trending angle... But the fuel rate can't increase until there's more RPMs... But the RPMs can't increase without more fuel... lol But seriously, I like the idea a lot, was interesting! (even though they are just trying to recreate a really crude "Throttle Body Injection" lol) I think where they went wrong is they should've used a DC drill motor and trigger as the "pulse generator" to keep it separate from the engine RPMs. Gas pedal is connected to the drill trigger, giving variable speeds. Of course, matching how much electric motor speed with engine RPM would be the real trick. Right now as it is on this vid, it's running too rich at low RPM, but then starts to lean out and can't make more power. (which he confirms) The reason you have to *go easy on the gas pedal" is because the air:fuel ratio (AFR) is way off and the engine has to catch up once there's more air... But then it leans out to much... etc etc paradox. If they still have access to the open internet, I suggest they lookup 1950s era fuel injection and how they went about tackling the AFR with only mechanical systems... If start by adapting the fueling system from a diesel Lada 🤔

[@Crepypastin2703]

I don't know much about mechanics, but I would say that placing the injector closer to the intake manifold would give better performance since having it as it is at the moment, the air reaches the engine before the fuel diffused by the injector. Using reasoning I would say that the injector closer to the manifold would solve that high rpm performance problem. Cars generally use the injector in each intake port of each cylinder and then the throttle butterfly comes from behind. In cars with single point injection the same rule is followed, with the difference that an injector supplies the 4 cylinders and this is located just before the intake manifold branch. I think the throttle is the correct size. Great video!

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.

add vacuum line to pressure regulator lower pressure at idle and rise at wide open throttle, you need less fuel at idle and more fuel on acceleration, you might need more than just 1 injector

[@EricErnst]

I like that you have more injection events as the rpms increase, but the injector "on" time decreases at the same time. I think you need an accelerator pump feature to squirt fuel when you move the gas pedal. I don't think the throttle body is too big. It's just a matter of incorrect fueling for the amount of air being ingested. A vacuum referenced fuel pressure regulator can also help reduce fuel pressure to lean out the mixture during idle and light cruise but add fuel pressure as rpms increase. Very cool concept and it could work well with a few refinements.

GM used a system like this called Throttle Body Injection. I had a 84 Corvette that used two of these throttle body injection systems for thre Crossfire Injection. only difference was that the injector mounted in front of the throttle body. In a normal vintage fuel injected car, they use a ECM that is clocked off distributor but then frequency divided so fuel injection pulses twice every cycle. then there is a thermal sensor that changes fuel mixture based on temp. Then There is a throttle position switch along with a Air flow meter, (little flap with variable resistor) that would richen mix with throttle control giving you a even mixture through throttle. lots of cars would also have a vacuum controlled fuel regulator that would increase pressure when there is less intake vacuum. Fuel injection is a neat system especially on the old 70s cars like the Datsun 280z

Something to remember, with the way you are running the injector, the faster you rev the engine, the shorter the pulse of the injector. This means that you have a long pulse at idle, and a short pulse at rpm. That is why it is flooding at idle and leaning out at rpm. That needs to be flipped somehow. How did you adjust the spark gap? Is there a way you could use the mechanical advance on the distributor to adjust that gap? Short gap at idle, long gap at rpm. Then to get a fuel adjustment, you could perhaps hook the throttle up to that pressure regulator. No throttle, low pressure. Full throttle, high pressure. Both these fixes are fully mechanical, still very cheap, and should make it run a TON better… all this along with a matched throttle body like you stated.

Get a potentiometer/variable resistor and hook it to the throttle shaft and feed your injector with it. Should raise and lower your fuel imput with the throttle. This should allow you to run a bigger injector to give it enough fuel at higher rpm

[@soupflood]

That would call for a variable potentiometer-controlled PWM generator hooked to a MOSFET that will open and close the injector.

[@michailrathsmann1385]

Add a vacuum line to the distributor and one to the fuel pressure regulator. Line to fuel pressure regulator will adjust the richness at low and high RPM. The line to distributor will adjust the timing for higher RPM or the injector to adjust its firing time. Can't wait to see the follow up video. Gained a new subscriber.

[@operator8014]

Fuel injectors take a bit of time to move from closed to open. At lower RPM, it is spending more time open than at higher RPM. Hence the low RPM flooding and high RPM leaning out.

[@jadesmith6823]

❤️😂

[@cliffcorbitt9494]

I've been a mechanic for a long time working on a lot of cars I never went to school for it but in my mind I'm thinking that an injector is holding back those PSIs while they have power going to them and the magnets holding the spring loaded ball valve take a lot of force when the explosion occurs as well. So yeah I'm sure it takes a little time for them to open and close even though it's milliseconds

[@AnalogDude_]

true, you need a micro controller with an algo that generates a PWM signal and a crank pos sensor.

[@jcpage305]

If you feed power to the injector via the power to the coil, you can use this setup on a electronic ignition and you won't have to install a kill switch to keep the injector from firing when the engine is not rotating.

[@jodilynnsmithers2850]

Worthy and brilliant idea and one day I will try this method on one of my customers... With their permission of course

[@RDCST]

The injection angle/time should increase with load and RPM, that's not possible with a distributor, so you should increase the fuel pressure using the vacuum in the intake port, behind the throttle body. The distributor is working giving a lot of fuel at low RPM and less at high RPM. Also you should add an O2 sensor in the exhaust system and a hallmeter to know what is happening.

[@killcar5nbike2]

Your on time decreases with RPM due to it being a fixed ratio of engine rotation to dwell angle from such a basic set up. Or put another way, you lean out the mixture with RPM.

[@volvo09]

Yeah. It's kind of operating the opposite of how it needs to right now, too much on time at low RPM, and manifold vacuum increases fuel flow further when it's needed the least. I haven't gotten into old vehicle ignition systems yet, but they did have distributors with RPM based dwell and a vacuum advance / retard right? So you'd be trying to make those work for you, maybe with some sort of fuel pressure regulator to drop pressure quite a bit at high manifold vacuum. Neat concept, it would work in an apocalypse, haha.

[@killcar5nbike2]

@@volvo09 the simplest thing I could think off is to use the distributor to trigger a 555 based timer, and a TPS to vary the control voltage. So a very simple throttle position varies duty cycle set up. Not great, but it would work far better than this set up, and still be super simple

[@ruikazane5123]

But the injection time also shortens and speed up as RPM goes up. Might be too quick that injector time is too short to actually open up the injector fully I would actually consider this on my experiment...trying to run a small motor with water electrolysis but instead use a 555 timer to modulate injector time (pulse width, can be milliseconds) and frequency (injection operations per second)

[@killcar5nbike2]

@@ruikazane5123 yeah, trying to ask an injector off a multi point set up for a car to fire twice per revolution at high RPM would be asking a lot of it. Alternating between two would probably just about cut it if they had a high enough flow rate.

[@albertp205]

Don't you really know that the Russian military is killing children and women in Ukraine? Pozdrawiam z Polski.

[@Technotranceism]

You definitely need something that can control voltage and pulse width to time the injector correctly, as for the pressure regulator they usually rely on vacuum to adjust the delivery and return. A good tinkering experiment for the students no matter what though, so good job 👍

[@alexcannons7106]

I really enjoy this stuff here are some of my thoughts, keep up the good work. Some early transistor ignition conversions used the points just to trigger the circuit and the transistor ignition provided a timed ignition pulse at all RPM the pulse would be about 2 thou of a second. This would give a better starting point, same fuel delivery per cycle, then a air bleed to fine tune idle. Something still lacking would be accelerator enrichment. I just went through similar development with a mechanical system I put on my motorcycle, not my invention but a challenging application.

This is pretty much the equivalent of an old school Hilborn fuel injection setup, but with one single injector. Multiply that by how many cylinders you have in the car and you have a low budget "gasser" fuel injection. Later edit: i have re-watched the video. You can see that he tries to put a happy face but he is struggling. There are tough times in Russia as well, right now. I fully support Ukraine but I have to feel sorry for the Russian people as well, they are close to powerless in stopping this disaster.

This looks like a perfect constant RPM setup. The only thing you needed to do is to give it full throttle to allow all of the air. When the RPM drops, the injector injects more fuel and increases the RPM.
