This is an awesome video! The fuel condensation is a fantastic example on why modern direct injection or even port injection is such a large step in increasing efficiency and reducing emissions in comparison to a carburetor. It also explains in a perfect visual representation on why more fuel is needed to start a cold engine, without the heat helping keep the fuel atomized you need more to make it run properly. There's even a reasoning to the old school saying of "carburetors make more power" due to the extra fuel potentially cooling the intake charge more than a port injection system alone could. Fascinating stuff.
Love when you make parts transparent. For people like me, stuff like that has helped me understand how things work immensely. Also showing what not to do and why, sometimes seeing something break or work improperly is useful in learning how it works and why.
@@heyitMeMcFlyunfortunately Only to the 3rd World mind is it a miracle. Go back a century and a half to where many of the same parts were being cast and machined for steam engines. Many of those parts were later adapted for gas engines in the U.S. and diesel engines in Europe.
i mean... seeing it transparent doesnt help to understand. esp when the concept is so simple. the vacuum created by pistons going down sucks air through the carb which pulls fuel from the carb bowl to the cylinder which is ignited.
@@diegoaespitiait helps. Always good to know just exactly how and what things look like where when doing whatever. I appreciate clear or cutout’s immensely. Id like to make a display of something, with cutouts or clear covers like an automatic transmission would be cool.
That's a great idea... I hope they try it out; curious to see that now! I bet even adjusting the frame rate of the camera will impact how it'll look with the strobe. It would be neat to see them vary the rate of the strobe several times in the same way, but with a different camera frame rate each time.
The more clear parts the better. Clear distributor cap. Clear valve/rocker covers. Clear transmission pan. Anything you can make clear to show parts/fluids moving inside an engine/transmission. The clear differential cover and oil pan are very cool.
The fuel condensing in the intake is basically why engines require cold start enrichment (i.e. choke on carbureted engines). Liquid gasoline doesn’t burn, only the vapor, so when the gasoline condenses on the cold engine parts (like the intake manifold or even the cylinder head and cylinder walls) it doesn’t burn, so you have to introduce more fuel in order to get the mixture to the point where the engine will run. At least until it warms up and the fuel stops condensing. This is also why many engines will run hot exhaust gases around the bottom of the intake manifold.
More importantly, this is why carbureted engines must have manifold heat to run smoothly once it is started. Quite often, in addition to manifold heat, you need air intake heating to prevent carburetor icing. Hot air helps improve drivability of a carbureted engine while it's warming up.
Every video you guys seem like you are having so much fun, I miss when I was younger working in a garage. I had friends into drag racing, street racing and demotion derbies, we would spend all week building the cars and run them on the weekend. Great video as always
This perfectly illustrates why manifold heat is so important with carbureted engines or with a central throttle body fuel injection. The fuel falls out of suspension and deposits on the cold walls of the tubes. A heated air supply would help. Make the intake air pass over a sheet metal stove surrounding the exhaust manifold and making the air hot before it get sucked through the carb. That will improve fuel vaporization somewhat but, it still isn't the same as a hot spot below the carb.
many cars in the 80s where i live had coolant flowing into the intake manifold at the base of the carb, warming the (usually) alloy manifold up enough to reduce fuel condensing on the manifold walls. warm air intake was more to prevent the carb icing in cold weather from water in the air freezing when it speeds up going through the carb venturi.
That was really cool. The best I've seen since it was on a carb'd engine. Great work! It's about as cool as the simple fuel injection you made and had a clear pipe in there.
The fog is so cool! Awesome visualization of fuel atomization. Can you make a transparent carburetor? Btw, what's the song at 5:56? I want to add it to my playlist.
That intake design is like a high-rise single plane. They work best at higher rpms. You should make a see-through dual plane with some way to heat the bottom to stop fuel from puddling. Maybe even a see-through carb so you can see the performance in action.
This perfectly illustrates the reason intake runners has smooth bends. Helps keep the fuel from puddling in the runners. Of course modern FI engines eliminated THAT problem by injecting directly into the heads.
With extruded aluminum, it could be done. Vlad and his crew have the fabrication skills. BUT... the runners would have to be heated the entire way. Exhaust heat under the carb and water jacketing for most of the length. Otherwise, so much fuel would fall out of suspension that it would barely run, if at all.
@@BlackPill-pu4vi exactly. its why old carb engines run like crap in cold weather if you remove the factory airfilter/box and fit an aftermarket one. no hot air intake to keep the moisture in the air freezing as it speedfs up going through the carb. exactly why those silly chrome panel filters used on shows like roadkill have so many running issues when they visit colder places than where the engine is originally set up. no need to keep rejetting the carb, just put a proper factory style air cleaner unit on with a warm air intake. its why they exisst!
If only you had a slow mo camera... We would've seen the air and fuel going to the cylinders one by one (and even maybe calculate the speed it goes in the process) That would be so cool to see !
Long intake runners must be smaller in dia to maintain high velocity of fuel mixture. Pulses you see are the reverse flow of ram induction. Runners should be around 19 inches long from bottom of carb to intake valve seat. This will put power at 3to 4000 rpm.
I'd recommend fuel filler neck for couplers next time. I'd also love to see a Lada with yamaha r1 carbs. Not sure about the engine displacement of a lada, but i run 4 yamaha r1 carburetors on my 1970 datsun with a 1.6l using fuel fill neck as couplers (it doesnt collapse under vacuum) and it sounds insane
There are some transparent parts for bike engines... Usually clutch covers or case sides. that let you see the clutch basket spin and get covered in oil. Kinda neat.
First I thought "when they mount this thing directly to the block, the vibrations will destroy it immediately" but then you decoupled it using shrink tubing😂 You guys rock!👍
This not only shows the intake, but the reversion into the intake tract from valve overlap at low speeds. That is the exhaust smoke coming into the tract from the cylinder head.
Really interesting idea! It would be great to make performance manifolds out of sheet plexiglass like they use on prostock drag cars. Most of them or made from sheet aluminum. Many years ago I had a Edelbrock ram manifold on my small block chevy and I would have liked to see the flow through it.
I think it would be cool if you could sand the inside of the tube halfway so u could still see and it would show the difference off smooth ports to ruff ports and how it affect the flow patern maybe use different grits to see if its better
@@davelowets why not its collecting on the tube i know thats not vaporizing and sticking to the intake would a semi ruff surface flow good and atomize the fuel instead of sticking being turbulent enough to help atiomiz it with out restricting flow i am not try to argue would truly like you know
Great video. But-this is essentially a long-tube intake. Its taking the idle mixture longer to get to the chamber. Take this configuration vertical (high-rise intake), it should be similar - although gravity will help with the fuel delivery.
Correct, That is why the factory used exhaust gas to warm the intake manifold years ago. The gas is almost always cold liquid and it takes some work to get it to a vapor. Modern cars tend to run at higher temps to get more efficiency.
A light defuser panel would have been great when he put that led light thing behind the intake. You can get one from one from a broken flat screen or something.
the h fuel is liquifying because the tubes are smooth and not ruff cast and that the intake runners are strait with corners instead of curves . thought of trying heat to bend the pipes
That would be interesting Hows about putting the intake manifold on exhaust side of the Cylinder Head and the exhaust on the intake side of the cylinder head
Very good experiment very educational! I had an idea of what it was doing but now I know for sure. Thank you, now do it again but with a lean fuel mixture and a rich fuel mixture and then see how lean you can go.
A lot of the 'condensation' is caused because the pipes are so smooth inside. The internal surface of the stock cast aluminium manifold is rough and that creates an air turbulence layer on the surface of the metal that keeps the fuel/air as a mist/fog.
That would be pretty educational for people to make almost anything you can on the engine transparent. Timing chain cover, valve cover, oil pan, distributor cap. I've seen transparent acrylic carbs on mower engines. Might be able to scale one up for a late engine. I've also seen transparent cylinder heads on lawn mower engines but with the intake and exhaust ports running through it, plus the valves with springs, and head bolts, I'm pretty sure it would melt or crack pretty quick.
That on the inside of the intake runners wasn't condensation it was the oil that you put in the petrol, it didn't look red in colour because of how thin a film it was making on the runners and you could also tell the way it ran along the runners it was too viscous to be water/condensation and the oil doesn't atomise like petrol does.
Don't take the manifold off yet. Point an adjustable timing light at it to make the flow "freeze" in midair. Should look excellent on the camera. If an adjustable timing light is not available, trigger the timing light of off different spark plug wires. The effects are fascinating. This is how we used to check throttle body injector flow patterns in the 1980s. Пока не снимай коллектор. Направьте на него регулируемый световой индикатор времени, чтобы поток «застыл» в воздухе. На камеру должно смотреться отлично. Если регулируемая лампочка времени недоступна, активируйте лампочку времени на разных проводах свечи зажигания. Эффекты завораживают. Именно так мы проверяли схему потока форсунок корпуса дроссельной заслонки в 1980-х годах.
it will be the same if you piped it where the carb sets ,many years ago I did similar I used an old refrigerator Basin and glued a top on it with a window to see in with one hole on one end where I ran a hose to the intake and cut to fit a carb on it on the other end ,the goal was to make gas and liquid separator for high milage experiments and it worked it separated the gas and liquid ok but it ran lean though and you can see mist fog when it ran it was pretty cool experiment.
It makes no difference whether the intake tubes are not or cold as far as the "condensation" in them goes. Even if the tubes are warm, it will show, as long as the throttle is closed and there is a heavy vacuum present. It's the vacuum that is responsible for the condensation.
Take a piece of your tube and pat your palm over one end with the other end open you'll feel the pulses and reverberations. Different diameters and lengths. Open and closed on the other end and slower and faster pats make for different results. Put a small piece of paper in the tube and watch the paper.
Great idea, 👍 did you think fuel reversion was only noticeable at low reves and only for half the distance of the pipes. Does this mean no need for long runners.?, allso it looks like the fuel turns bends with no fuss or no differance real differanc to flow. what do you think. Mike
Noticed that the pattern of the condensate was different for different cylinders. would be nice to know how the distance of the tube or pipe affects them and the performance... Just thinking nice one!
The major reason for the fuel condensing on the manifold is because the walls of the tubes are way too smooth, rough walls promote turbulence which holds the fuel in the air flow, thats why you don't polish manifold runners or inlet ports, you're wasting your time and robbing your engine of power.
this actually shows few things... Smooth surfaces in ports of engine causes gasoline fall from the ride of air flow... that's why they always say "do not polish port surfaces" second thing is that those runners are bit too large for engine, air flow is reduced due to this... but nice test! :D
I always heard smoothe intake ports were bad, because the fuel will condense on the walls, and cause pudding, causing the engine to nearly flood, or cause rich then lean conditions, I'd like to see screen wire in the ports to see if the screen keeps the fuel atomised !
I wonder how much of the liquid condensation you can see is actually residue from the oil you mixed in the fuel? You think that pure gasoline would do the same?
We see a prime example of why polishing an intake to a mirror finish is detrimental to performance. Quite often the rough sand cast aluminum helps add surface area for fuel to interact with air. Of course this changes with direct injection but for the most part guys wanting to port heads should leave the mirror finish to the exhaust side only.
It would be totally awesome if you guys make an engine run with everything transparent except the block of course. Even have your diff cover installed on the car and show us all of it together.
At this point I think you guys should make an entire engine transparent.
I was going to say, now they should take their transparent oil pan cover, valve cover, and anything else they've made and put them all on one engine.
cut inspection ports between the webbing, and mount the engine in a stand
It might be easier to make an invisible engine.
Yes! Even if it only ran for a few seconds it would be cool
Add a transparent distributor head✋😁

Good idea, that would probably work great.
Was thinking proper strobe lamp, because its' rate can be adjusted, but you can get dial adjustable timing lights, so that works.
Exactly, turn off the shop lights and concentrate the timing light on #1 cylinder to find if the individual pulses can be distinguished or not.
That's a great idea... I hope they try it out; curious to see that now! I bet even adjusting the frame rate of the camera will impact how it'll look with the strobe. It would be neat to see them vary the rate of the strobe several times in the same way, but with a different camera frame rate each time.
A transparent distributor cap would be interesting, not very exciting, but interesting.
you can buy those, most of them are really low quality tho
Everything transparent would be ideal.

It's about as cool as the simple fuel injection you made and had a clear pipe in there.
Video idea: Make a transparent engine block
it will work for three revolutions, and fall apart once the engine reaches idle.
Yea probably but it will still be interesting to watch
I don't know if its even possible for compression heat probably scratching on the transparent material
They actually use sapphire engines for RnD IIRC.
@@4G12 Nice username. I have one of those in a Hyundai Pony ;) (minus the T)
3D printed intake with rifling inside the tubes next? See if it creates a vortex and injects better?
You're too young to remember the "Tornado" throttle body spacer, aren't you?
Didn't do fuck all for horsepower OR efficiency.

Very cool . That shows a very typical phenomena. Atomisation is good; but can always be better huh. Fuel injection really improved matters.

Amazingly no backfires in all that, which would have been disastrous. Great job!

The major reason for the fuel condensing on the manifold is because the walls of the tubes are way too smooth, rough walls promote turbulence which holds the fuel in the air flow, thats why you don't polish manifold runners or inlet ports, you're wasting your time and robbing your engine of power.
choice of music totally got me...thats basically what i listen for like since it got invented 24/7 365 xD yayayayaya
New to the channel-American watching from the State of Rhode Island in the U.S.-FANTASTIC! THANKS FOR THE POST-BRO!-PEACE! 😇
I'm not sure the condensation you are talking about is water. I dare bet that was fuel. Either way, good vid!
actually way more interesting to look at than I first thought
How is does this channel not have more views currently? Is it being shadow banned.

its not that the fuel condenses as much as the fuel relies on air turbulence to keep the fuel and air mixed in suspension as it is.
Garage 54 all about that Dew. Original and Code Red to fuel that Lada.
The reason why you see the liquid on the clear gas is it fell out of atomization that's why you don't polish and intake
Like the big exhaust you guys have done . Only do the opposite , see how quiet you can make a running lada.
I wonder how much of the liquid condensation you can see is actually residue from the oil you mixed in the fuel? You think that pure gasoline would do the same?
Pretty damn cool!
We see a prime example of why polishing an intake to a mirror finish is detrimental to performance. Quite often the rough sand cast aluminum helps add surface area for fuel to interact with air. Of course this changes with direct injection but for the most part guys wanting to port heads should leave the mirror finish to the exhaust side only.
Would be interesting to see what happens when you use a heat gun to warm up one of the intake runners.
Nothing...
The only thing that you would see is possibly the plastic melting.
It would be totally awesome if you guys make an engine run with everything transparent except the block of course. Even have your diff cover installed on the car and show us all of it together.
Thank for the efforts to make that type of content!
Maybe try some UV dye in the fuel and light it up with a black light, especially one that has a strobe effect
That thing is running super rich.

@@5.43v except they arent available in all markets and not everyone has somewhere to plug in a block heater
That must be why you can make a manifold for an inline 4 engine and put a single carb on just one end
Thats why intake ports should not be polished. Condensation is bad thing. But no problem if direct fuel injection is used.
I honestly feel like this would be a cool looking cold air intake if it had less sharp turns in it.
