No problem, we used to call them single point injection systems. You can even regulate the fuel flow mechanically.
It’s called TBI (Throttle Body Injection).

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...
You are very knowledgeable
Do you think my idea would solve your issues ?

Great video. I wonder if an injector would work through a Mikuni carburetor. Perhaps the slide could control the injector jetting and the carb act as the throttle body. It may atomize better, and feed a 4 cylinder engine with a 1 cylinder fuel supply.
Ah, you just described the K-Jetronic :D
I wish they would make a follow up video fixing the leaning issues and we would see a fuel injected high rpm lada
@@teslatrooper85 l jetronic is kinda similar
Try adding a vacuum reference from the inlet manifold to the fuel pressure regulator to increase fuel pressure as you open the throttle.
good idea!
You mean decrease as it will create more vacuum under load
That's what I was just going to say. That should increase fuel pressure by about 10 PSI under full load compared to at idle. Not nearly enough to make this setup to work properly by itself, but it should help a bit.
@@kirilakmadjov8307 Adding a vacuum reference would INCREASE fuel pressure under load. Intake manifold vacuum DECREASES under load.
@@averyalexander2303 you were right i did my research.But yeah at the end of the day he needs a reference for that fuel pressure regulator in order to get it to work smoother
This is basically Throttle-body Injection (TBI); some early 90s cars had this for a few years.
Except TBI is computer controlled. This is mechanical controlled.
@@normanguzman417 fuel injection doesn't need to becomputer controlled to be called fuel injection. Chevrolet sold a couple corvettes in the 1950s with a fully MECHANICAL port FI system fitted, something German cars have fiddled with for decades as well.
This is still TBI.
@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.
@GGALLIN1776 That's why I stick to carburetted rigs. Computers fucking suck.
@GGALLIN1776 Coulda swore GM dropped that shit like a bad habit when they switched over to OBD-II in 1996. No matter, those TBI systems are easy fixes when they act up. Just rip the throttle body off, yeet it into the nearest 'art' bin, and install a 2bbl carb + fuel pressure regulator.
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.

@@DiscoFang I know what war is. I also know who suffers and who profits. I also know you won't get the truth from any mainstream media or social media. I guarantee that every politician bought oil and gas stocks before this happened.
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 %.
This is exactly the issue. Injector pulse width or pressure needs to be changed with engine speed.
indeed, have pulse width vs rpm but no pulse width vs load (manifold pressure). Should have a lambda controller that gives feedback to a fuel pressure regulator or pulse width adjustment (and above that an acceleration enrichment and warmup enrichment)
Eliminate the vacuum advance?
@@scattkiwiman No need for a "proper" controller. An Atmel micro with a MOSFET and a few other components should do the trick nicely. If it weren't for the, uhm, "current political situation", i'd be able to slap together a circuit and have it send off within a couple of weeks.
vacuum reference fpr would make this run way better. maybe a properly sized injector would ease tuning lol
If you can do basic electronics, a mosfet and an NE555 set to one-shot mode, triggered by the distributer and pulse length controlled by a variable resistor connected to the throttle input would give you some control of mixture without needing an ECU. On the other hand, it's probably easier to setup an arduino to do the same thing, and would be easy to tune.
Yep, arduino controlling relays/mosfets connected to the injector. Also arduino controlling a pwm servo controlling the throttle body. Encoders detecting rpm, maf detecting airflow to allow for calculations on injection output.
@@kennysboat4432so basically a speeduino.
I own a Lada Niva 2001, with a Rochester TBI model 700, mono injector equipped. No complaints

Good men like you guys don't need to be dragged into another pointless war. You guys deserve a better leader than Putin. 🌻
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.
"H G" pointed the right direction for a setup like this, needs variable fuel pressure, low for slow, high for fast. a regulator connected to the throttle maybe?
They used cpi in the states too
The 1988 EA falcon also had multi point fuel injection, atleast on the S variant
@@gfalcon1375 yep, and also I believe the fairlanes and fairlane Ghia's. Optional on Fairmont's. I had a Fairmont Ghia with CPI.

@@loud_n_lowtaco200 True, sad but true.
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
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.
They've done just about everything including running the car on wood
you absolutely can, it's the same procedure as making it run on propane, you just need to set the air-fuel mixture right
Eens
You can't. All the tolerances would need to be much much tighter. Toyota can bearly get it to work with a whole team of engineers on the issue. And even then it BEARLY works
@@cb6112 the problem is stopping the process fast after engine switch-off. It runs on hydrogen just like on LPG
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.
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.
I did not even realize the "on" time thing. You are smart.
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
exactly!
They could use the intake manifold with a vacuum switch to connect / disconnect in capacitor across the fuel power supply and ground it should smooth the pulses a little and open the injector a bit longer. Capacitor size would be critical... otherwise it would either be useless or just open up completely at part throttle haha. Instant dragster style fuel injection...
Adjustable Variable rate FPR could resove this.
Don't you really know that the Russian military is killing children and women in Ukraine?
Actually, thinking about it, they should just get rid of the throttle body, tune the pressure to give optimum fuel at max revs and use the clutch as the new throttle. Problem solved.
One of the best mechanic channels on CZcams
This is simultaneously hilarious and absolutely genius. Most people will never understand how insanely knowledgeable and smart this guy is.
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!
Awesome job guys! I liked the distributor as fuel timing. I wonder what your fuel pressure was. And maybe have a second pump activated by contact switch off the throttle body to boost the injector at higher rpm. Thanks for sharing.
Or could you connect the fuel pump to an electric rheostat controlled by the gas pedal. Sort of like a light dimmer.
@@inmyopinion6836 simple and elegant!
Brilliant channel, very informative 👍stay safe , Love from the UK .
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 🤔
That'll teach me to ramble before I scrolled through a few pages of the comments! lol
TBI, mechanical fuel injection, rich-idle/lean-revved... All mentioned!

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
Brilliant. Single point injection! Works increasable well considering there is no duty cycle modulation on the injector. Thanks G54!
@@ccox7198 I would think the injector would lean out as it revs higher because of the lack of modulation. The faster the revs the shorter the pulse to the injector because it is just a points system.
The duty cycle come from the dwell time from the distributer used to trigger it.
@@cS-nf2dg yes but it's fixed.
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!
Thats cool
Great stuff! Another fantastic experiment. Using the old points-type distributor was genius. Cheers from Canada!
This is the guy you want as a neighbor if SHTF as all he needs is two elestic bands and some second hand sellotape to fix anything!
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. .
you can people do it all the time. you just have to use a 2 wire electric fuel pump get a carb style intake. on alot of chevy trucks you can swap an old carb intake to a fguel injected motor take out the ecu run a 2 wire pump with 1 wire alternator activated by the same wire as pump an msd ignition box for timing and a separate hei distributor you can make it a carb motor from fuel injection. done it once myself.
that window trick i gota try it for my turbocharged system right in the middle between the intake manifold and pressurised air cleaner downstream from the outlet of the 76-70T so i can see if it's icing up or not and air flow/dirt stoppage ect
@@mattquarles7029 Yes, I think quite many engines designed at or near the carb-to-efi transition era, have bolt-on swappable carb and efi, and manufactured and sold with both versions. For example, Toyota had 4A-F carb engine, and 4A-FE which was same but carb system parts replaced with similarly fitting injection system parts.
I took my drive by wire 1.9 Tdi
And converted it to mechanical pump no computer.
Doesn’t even need a single wire to work
@@fastinradfordableloved my 95 TD. Had it running 32psi boost with a manual vacuum valve in the glovebox and the mechanical pump turned up a little😅 problem was after a while it sheared the crank pulley keyway and grenaded the engine. Apparently the TDI pulley is the fix for the older cars. Didnt do that myself but heard other Dub nuts do.
I'd love to see you turbocharge a fuel injected car, and use an adjustable rising rate fuel pressure regulator, with fuel jet from a nitrous kit to tune for the extra fuel (instead of adjusting the normal fuel injection)
You fellows have such a great time doing what you do ..... and the whole world seems to know it! Thank you for a great channel and great, articulate translations! :)
Should've had a staged setup with an additional 2-3 small injectors that would turn on at different throttle positions. Also, a referenced fuel pressure regulator would probably be useful. What you have currently is, in essence, a GM TBI setup. With the exception that the injector is behind the butterfly instead of in front of it.
It's hard to watch these guys work without thinking about all the silly stuff I wanna try.
Look into the "Speeduino" project. It's an open source ECU that can be built dirt cheap and will run pretty much any motor.

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.
can u share with us more about the system that you put on your motorcycle? do you have a video about it?
We had single point injection systems on many British cars, even the humble classic Mini had a single point injection system that squirted into the inlet manifold, Ford Sierra's and Granadas baser models had SPI and Rover cars from the 213 to the 820 had SPI systems too.
My Fiesta had it. Worked great.
Same with my old Fiat Cinquecento and Seicento
yes you can there called tbi or trottle body injection , been used on production cars as a cheaper option to mulipoint fuel injection they still use a computer and lambda sonde to measure the fuel ratio
you probably need to base the fuelpressure of the manifold vacuum to get it to run ok enough
AKS Single point Fuels injection.
AKA Center Point Injection
That was a really good one to show that you don’t need an ecu the car will probably run better with one then without but the ecu and all the sensors can brake so you need to find the problem and so on and so on that is a really easy setup to work with!!
This is definitely an awesome thing to explore, I'm pretty sure someone out there already worked with it. Like the people that made Smart Carburetor. Them thing is damn expensive but... it works like a charm for almost every bike that uses carbureted engine.
It's good you guys are handy, you'll probably need to be for the next while.

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
That must be a great place to work! You guys do so much fun experiments. Great stuff
What if you had no timing for injectors? Just throttle position. Have a tiny injector for idle & another tiny injector for above idle. Just on or off.
Maybe a third injector at full throttle.
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.
This was fun to watch. Best wishes from the USA. Keep up the fun projects.

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.
❤️😂
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
true, you need a micro controller with an algo that generates a PWM signal and a crank pos sensor.
13:51 I had to watch it over n over as it like a mechanic comedy! LMAO
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.
People in Canada: "I can't drive today, the gas prices are to high."

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
That would call for a variable potentiometer-controlled PWM generator hooked to a MOSFET that will open and close the injector.
Love the creativity and ingenuity. Great channel.
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.
Can you replace Putin with a decent lieder ?
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.
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.
@@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
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)
@@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.

EFI hardware usually monitor three things; RPM (the speed the engine is currently running at), throttle body position (the position that's actuated by the gas pedal) and finally Oxygen sensor usually before the catalytic converter to check if the engine is rich or lean - the computer usually decide when to run a bit rich or not at idle (during cold weather, the engine usually run a bit rich so it can heat up the fluids so they move around a bit better before or during the drive). Otherwise it is actually doable, as in the USA we have the EFI upgrade package for the classic carbureted engines from Edelbrock (they also make rather good aftermarket carburetors).
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 👍
Hope everyone is having a great evening! Enjoy the video.
@@razvi01 goodbye
Awesome vid! Greetings from Ukraine!
You can use a relay between the distributor and injector to shut the injector off when you turn the key off with your ignition source or toggle switch and / or even a oil pressure switch for redundancy.
Putting the throttle body closer to the manifold will likely make it smoother and more power. The air/fuel charge has so much distance to travel to its cylinder where you may only get half of that chagre now essentially. Or if anything better atomization in the cylinders.
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.
I've been asking for a pulse jet on a lightweight Lada for 3 years...............maybe this is this year.
That worked exceptionally well given the colder temperatures it was running in. Great video.
I had a VW Golf Mk3 with a 1.4 single point injection engine. For a 1.4 it was ridiculously slow (54hp I think). My 1.2 multi point injection corsa had 75hp! It's amazing how much difference a few more injectors can make. (Along with other tweaks obviously).

We are not politicians, we are completely against the war, we are here to share knowledge and to support the Russians that do not represent what's been happening right now. I hope you guys take care and do not stop recording.
All you’re content is brilliant, all the best from uk 🇬🇧
What is your view on Russia verses Ukraine?
@@jadesmith6823 the west have alot to answer for this should never have happened.
@@jadesmith6823 really not that simple. Especially when right sector is involved. For instance UKR forces dropped a missile on an Azov hq as revenge for them targeting a UKR general. Unless you can understand the history you won't understand what's happening now.
@@jadesmith6823 , rewind to 2014 the neo nazi group called the azov brigade were attacking ethnic Russians in the Donbas region this little war has been going on for eight years , and I. That time the azov brigade has been made a regiment within the Ukraine military, so that is what putin means when he talks about denazifiying Ukraine, it’s a sad state of affairs, and western powers in my opinion did not negotiate or allow more negotiations or want more bit lacklustre , but look who’s in the Whitehouse need I say more , also I find western leaders hypocrites bush and Blair invaded Iraq killing thousands destroying towns , but that has just been swept under the carpet the fact there were no weapons of massive destruction, the hypocrisy is sickening, is Ukraine being in nato worth the blood shed , plus agreements have been broken or they would be if Ukraine joined NATO , just hate seeing women and children fleeing leaving there men behind it very sad .
@@darthweeble7817 so who is physically there?
Greatest thing tried so far, you guys rock!
The 88 to 92 Ford Falcon here in Australia had Centrepoint injection, which was like one big twin nozzle injector straight into the intake manifold with a throttle body. It also had a fuel management system to run it.
Great stuff 😀😀😀, I love Australia, the Citroen DS featured a fuel injection system with an extra set of points in the distributor, and electronic regulation of the electronic injector duration....in the early 70's 🤪
can your next video be
"replacing Ukraine invasion with Peace"
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 video would have been recorded months ago. Further Russia is blocking more and more apps so I suspect CZcams videos out of Russia will cease soon.
My '90 Honda Civic had a setup like this. One large injector, a backup injector, all being fed into basically a port feeding carburetor.
Every single episode I'm amazed by the simplicity in which you find simply the easiest route to your solution Russian mad scientist geniuses.
I'm glad to see you guys haven't been "canceled" by youtube over the whole Russia thing. Love you guys. Keep up the good work!
notification squad, Have a nice weekend guys!🔥🔥🔥
Nice to see you! Business as usual IS BEST!!!
Awesome project, what would happen if you used the vacuum advance on the distributed so the injector can fire a little earlier with the revs higher? Also for better throttle response you may need some style in accelerator pump for the extra shot of fuel when stabbing the throttle to make up for the massive consumption of air being introduced. Great job. A 107.7% success
Hello from Sweden (Y)
What is your view on Russia verses Ukraine?
@@jadesmith6823 Media told us russia invaded ukraine for no reason at all, i dont know what your thought is, i guess there is more to the story than what we are told, media likes to blame putin for everything
@@jadesmith6823 What country are you from? what are u guys being told?

Glad to see this guy still up and going. Not real familiar with where he is, but I hope he's not hit with what's affecting Russia these days.
"hope he's not hit with what's affecting Russia"
affecting Russia
AFFECTING RUSSIA?
@@johndrachenberg2254 The whole situation over there: Their thug president bullying his neighbors and the world, and the sanctions levied against him for it. causing economic problems for the rest of the country. Putin and his cronies deserve that and more, but it seems to be the people who are hit harder.
This is awesome, would love to see a dual injector setup that uses a centrifugal clutch that allows for a distributor to activate at higher rpm and have another injector fire for the higher rpm. Or maybe I'm off and a better setup for the airflow would work better. I'm sure a smaller less complicated setup would work just fine
I bet you could have the distributor run the electrical contact points through that centrifugal clutch in such a way that it activates a second injector at medium rpm and a 3rd at high rpm with very small injectors being able to fine tune air fuel ratios. If not, 3 distributors work too.
As another user commented you could use the vacuum pressure to make an increase in gas flow as well and decrease as pressure goes up. I think combining it with this could probably give a really good setup that acts in a more tunable way if a setup was built for it and machined into one single setup. With each injector made to fire at specific rpm range, duration added, and during quick throttle opens more can be made to inject during that to help with throttle feel. It doesn't even need to be much. A psi extra or slightly more at low rpm and medium rpm would work. Maybe high rpm like 4.5k to till max as well for quick high rpm throttle feel?
Don't you really know that the Russian military is killing children and women in Ukraine?

Thats a nice idea!
Thank you for still doing this Videos even if you probably won't get money from them anymore
They deserve to . It's discrimination if you ask me .
how about war ? in ukraine , do you know about that ?
And ?
Much love for the Russian people! No love for evil Putin! Keep putting good into the world G54.
Great video. I wonder if an injector would work through a Mikuni carburetor. Perhaps the slide could control the injector jetting and the carb act as the throttle body. It may atomize better, and feed a 4 cylinder engine with a 1 cylinder fuel supply.

@@albertp205 Wrong video or comment. But since this was mentioned how about you go to tell Ukraine military to take better care of their weapons, so AA missile wont go haywire and slam into apartment building and then get accuse Russia for it, or post Syrian war drone footage as their "stunning victory" over Russian AA systems... Propaganda works both ways and one should not trust nether side of this conflict.
You just need to invert the signal from the distributor. At lower RPM it has more dwell/on time. At higher RPM you are getting less dwell/on time. This is exactly opposite of what you want.
You can do this with transistors or MOSFETs. Invert the injector trigger and it will run perfectly fine. Mechanical Diesels work this way. Throttle input and RPM determine fuel injection.
@Tiporari where would you connect the resistors? Would regulating voltage on the injector help
I hope you guys can stay safe with all the shit going on.
Peace to all.
