- Ever wonder what's happening inside your catalytic converter? I Make a See Through Catalytic Converter to see what's happening inside the catalytic converter when it's functioning.
you can clearly see that when it's not within its normal operating temperature it's not doing too much, I'm guessing this is why most cars put out the majority of their pollution during the first 5 minutes of startup.
if you're interested in learning more about how the catalytic converter works and the process that happens inside there are a few links to some really good videos below

Check this out czcams.com/video/Jj-ufVglr6M/video.html a very informative and entertaining video on the catalytic converter.
i feel like you should wear a gas mask sometimes
You make some incredibly interesting videos man!
Hi makes a transparent Supercharger
Bhow much for scrap metal
Great video im sure you can find a way to fit the catalytic pice a little better and then make some videos of clogged catalytic vs cat cleaners im really interested to see how good they work but you definitely did great on this video.
As an engineer who works for a company that designs and manufacturers Catalytic converters, this is awesome!!!! I sent it to my whole team!
Thank you so much ! I've been waiting for somebody who works in that industry to comment.
Can you tell me why a California Cat Converter is $1200 vs an out of California cat converter?
@@dudewtf1776 Can't say exactly as we just build em, so I don't always know the application. But usually, it's a few things, more platinum on the substrate means a better reaction and a better burn. But also means more money. Or the addition of another substrate so you have twice or more the burning power. That's what adds cost, more of a costly metal. Or more of the substrate brick itself. (Move to Michigan, we don't even have inspections here lol)
@@dudewtf1776 How about a starter 2 br condo is $800k?
Ian, i work for Corning Incorporated the company that invented it and sold the first one to GM in the 70s. i work in the plant where it all started
Amazing job! I've always wanted to see a catalytic converter while it's functioning! Looking forward to the next video.
Project Farm You guys should definitely do a collaboration video
Yes! Collab!
not much to see honestly unless something is wrong. They won't "glow" unless there is way too much fuel in the exhaust. Since what is happening is just a chemical reaction that just generates heat. automotive 3-way converters generally run at between 1200 and 1600 degrees F when they are operating properly, but can work as low as 800 degrees. below that, they don't operate correctly, and above 1800f you start to damage the retainer/holding material honeycomb.
@@chubbysumo2230 You're right.
In newer cars with leaner engines can spit out exhaust gases at around 900-1000 degrees C, most likely turbocharged cars, but even a NA engine could do that.
The temperatures are only there at max. Load, but constantly driving 100-130kp/h also get's the converter toasty. ^^
The Video showed why the coldstart phase is so important: The converter warms up fast and sooner starts to break down the exhaust gases.
Thank you!! That last video you posted, it was just hilarious!!
From a welder fabricator that does everything from building my own computers, to doing all the work on my own car it's nothing short of epic and exhilarating seeing the freedom being able to make all your own parts gives you. Seeing your videos motivates me to follow my dream, building custom parts/3-D printing/fabrication. Thanks for sharing your videos they are always epic. Especially enjoy the slowmos.
same here. i love manufacturing!
hope you can make it a reality brother
@@WhuDhat You as well, follow your dreams, and remember to help our brothers and sisters on the way.🙏🤝
The catalyst starts working long before it starts glowing.
The outlet is usually hotter (+50°K) than the inlet on a controlled 3 way catalyst.
The maximum temperature we measured was 950°C at a VW Golf 2 GTI (US model). Full throttle at 190 km/h uphill.
The normal operating temperature is between 250°C and some 500°C
Greetings from the founder of a German catalytic converter factory.
Holy cat, 950°C!
that's a pretty incredible temperature tolerance!
@@Werepie I'm not sure its meant to tolerate that high a temperature to be honest
How can one tell the difference between a clogged cat and one that lost active material? Is there such a thing as cleaning the cat (whatever method - fuel additives, washing after removal etc.) or is it snake oil? Thanks.
@@cristianstoica4544 A catalyst does not clogg if it's installed at the right place. This means: No fiber filled silencers before the catalyst.
If it cloggs nevertheless it means that the substrate is molten (which happens at above 1200°C) and the catalyst is irreparably destroyed.
If there should be fibres on the inlet (for whatever reason), just use compressed air to blow it out gently, but avoid inhaling anything (wear a good mask - FFP2 or better and protect your eyes).
If the active coating has left the game, the catalyst cannot get reactivated without an new washcoat and new noble metals (Platin, Rhodium, Palladium). All the "catalyst cleaners" are snake oils and may cause more damage than they would help.
Water does not help anything but might cause damage to the converter: If it sucks into the support mat, blowing it into pieces once it gets hot again.
COOL story bro.
Take a scrap piece of leftover catalytic material and hit it with a propane torch until it is red hot. Cut off the flame and then quickly expose the red-hot area to a gas stream and you will see it glow red hot again with NO open flame.
Cody’s lab did a video on catalytic material some time ago. Worth the watch.
Thank you for the very cool video and please keep up the great work.
Thank you and regards to Briggs
Butane soldering iron does the same thing.
Funny you say that, I had a shot that I was supposed to use in this episode but I ran behind schedule. I take a piece of catalytic light It up get it warm and I not only hit it with propane gas, I hit it with a scary amount of propane gas...lol. it look like the damn sun !!!
Dope
@@WarpedPerception That shot is going to make to one of your channels eventually right?... I want to see that shit...lol.
You see flame because the catalyst can't keep up and there isn't enough oxygen stored in the catalyst to do it's job. An EFI system is constantly switching slightly lean/rich to allow the catalyst to store oxygen to allow it to burn HC when present. When exhaust in this video which is super rich (orange flame is indicative) reaches atmosphere it combusts with a flame. You see some flame at the back of the catalyst here because there is some reverse flow every stroke. Excellent video.
In the 70s they had cats and used carburetors with no computer. They did inject air with a pump to help burn the hydrocarbons. 76 Monte Carlo and 80 Citation v6 were examples.
What I found most interesting was the difference that was quickly apparent between the inlet and outlet sides of the glass! The inner surface of the inlet side very quickly became dark and cloudy, while the outlet side after the honeycomb stayed clear and transparent - a perfect visual confirmation that it does what it is intended to! Great video, thank you!
Sort of, anything blocking/restricting flow of exhaust will get sooty.. I done enough custom exhaust work on my own cars to tell you that.. see y pipes with door build up after the cat.
It's actually the opposite - the inlet side was clear while the outer part was dark.
It does something but it's just breaking down the ash and gasses into another form NOT removing them! Burns cleaner but the particles are just smaller now. You can stand next to a running car and not smell anything but still start coughing. We're still being affected the same way.
@@enigmareach1129 it's still better to be breathing mostly carbon dioxide instead of breathing in nitrous oxide and other worse stuff

@@tylerwhite3248 Really, cool to know thank you. Yes i love my GP, & my 3.8s (had a bonneville before, its' 3.8 is why i stuck with the line..). I might research it more now that u mentioned it. Purrs like a kitten and the 02s and mufflers are brand new, but I'm not doing the cat just for the heck of it, I've analyzed it over and over with my OBD and it's fine. I have begun to notice that others with GPs tend to I have mufflery sounding problems too, I assumed it's something with the dual exhaust but I'll look into 3.8 emissions issues
@@iditarod4081 The muffler issue is probably the resonator. They always rot out. I just cut them out and replace with a glass pack. Runs just as quiet. Not sure of emissions, as we don't have to deal with that here
When I was a younger I LOVED blown up diagrams, cross sections, etc and had a bunch of picture books explaining/showing how things worked or what they looked like. Your see-through series takes me back to that same curiosity and wonder.

this is why you dont park cars on tall grass when you've been driving a long time.
I know someone whose car burned down as a result.
pdgeman or dry leaves...
Damn I wonder how many wildfires started due to this
Funny because if you dont have cat then youd often have backfire that could really start a fire
@@bernatzel17 yep. My old 66 Plymouth was sitting in a field for a cpl of years fired it up backfired because the gas was old and plugged one of the jets.. As it back fired shot flames out. Lit under the car on fire. Drove it to a where e dirt was. Grabbed a hose to put the field out. Luckily it was not a really dry field.
You can also just heat the honeycomb with a torch to get it warm and then put the torch out. Then just blow the gas from the unlit torch through it and it will burn without a flame and get the cat material orange hot. I always found it fascinating to watch something burn with no flame because it's just so counter-intuitive.
Seriously as a mechanical student you are teaching better than the University. I never understand the work of the cataliseur better like this wonderful video.
“I started running rich and the cat LOVED that!”
*in reality cat did not like that and in fact can be damaged by running too rich*
Lol... Good point. Well I guess I should have said " I loved that"
Warped Perception: [Loved that]
Cat: [Did not love that]
Everyone else: [loved that]
I always thought the lean mixture will heat it up and burn the carbon off cleaning it but didnt think rich mixture would actually burn the cat by overheating.
I was so sure rich mixture would foul it like a plug :D
@@eamh2002 there's a difference between cat and DPF wchich indeed is made to burn carbon
Yeh
Cat converters are large honeycombs of platinum, palladium and rhodium, when the toxic unburnt gasses like carbon monoxide pass over them, they get pulled onto the surface of the metal, the high concentration of the gasses on the surface forces them to react and turn into non toxic gasses like co2 and oxygen
Also the reason leaded fules for banned, is the lead atoms would permanently bond to the metals in the converter, getting rid of their ability to catylyse these reactions, destroying the converter
Well, that and, you know...lead.
@@sentry4944 Lead isn't in fuel anymore and is not part of the catalyst either.
So that's why in Blues Brothers Elwood says about the Bluesmobile, "It's a model made before catalytic converters so it runs good on regular gas." Meaning, regular leaded gas. Nice!
Actually, exhaust catalysts are large honeycombs of ceramic material with traces of platinum, palladium and rhodium. The reaction is intended to produce CO2, water and N2; oxygen is used up in that process.
Lead poisons the catalyst, and makes it so it doesn't work properly. Lead also poisons people. Banning tetra-ethyl-lead use in fuel was a huge benefit to people, not just catalysts.
@@willmcgo8288 Sure but it made the cars run worse without the leaded fuel because the TEL also acted as a lubricant for some engine parts. So older cars either need lubricants added to the no-ethanol high octane fuels they were designed to run, or you need a modern (post unleaded era) engine in your old car.
As a auto mechanic engineer of 52 & years your video is one of the very best I have seen.!! Well done Mr warped!.
This is absolutely the most under-rated channel on CZcams. The work put in and production quality is extremely great, and why this is not on the discovery channel eludes me.
agreed
The best part is when it breaks the seal creating a leak and turn into a pulse jet in slow motion! Nice.
I noticed that too, but checked here to see if somebody already commented about it.
@@Metal_Master_YT Drawing oxygen in to complete combustion
I'm currently on set filming a new years video for the channel, I'm going to check everybody's comments tonight!!
Warped Perception I would like to see through a turbo it would be interesting
I made of one of the first Cats for GM when I was younger, it was sent to Arvin Bosal in I think Belgium for testing. We then made all the lightweight stainles manifold and heat shields for a few years at prototype stage. Great experiment to see how they work. I also noticed that the internals have changed removing the rolled fine wire mesh and the asbestos paper and replacing it with something which looks much safer. At the time many cars adopted the heat shields with two pieces of aluminised steel with a layer of asbestos paper between.
The flames at 5:52 happen because that tiny piece of catalyst was overwhelmed (can be seen because the whole piece got red hot), leading to flammable gases exiting the exhaust.
This was fun to watch. My father was the lead tech in R&D at Briggs and Stratton 22 years ago and that was back when they were testing putting catalytic converters on for california. He also did high speed photography for them and I got to watch the films of some of their tests trying to develop the converter. Fun stuff so thanks for this one :)
those sliced cats does look like some minecraft structure
It really does, that's exactly what I thought when I was building it
here in germany the short form is kat and i was like who tf slices CATS in half o.0
@@3lp4u my exact thoughts when my friend was listing his cats as second hand and selling for huge bucks. I'm like how does it look? Fluffy? Short haired?
Turns out he wants to swap his performance catalytic converter to stock for his honda.
ducttaperulestheworl yeah I’m not gunna lie, ever again
The exact thing I was thinking 😂
The high speed actually did reveal something neat on the small converter test. As the piston was going through its stages, you can see the flames/smoke would get pulled back into the exhaust very slightly. Than get blown away again. Very cool!
That’s what destroys Gallardos engines
that slow high def production is top notch, plus the editing, you can do it all

@@LuxuryNoCap THANKS for sharing your immense expertise on this subject
That low motion footage looks even more EPIC with that EPIC music.
This is a "burning up a catalyst" demonstration - not a catalytic converter demonstration. Essentially this demonstration combusted fuel resulting in temperatures that destroyed the catalyst. Typically a catalytic converter will degrade at temperatures above 1200F -.
It wasn't destroyed though. The most damage that was done was just from sawing it into shape
8:10 you don't need to worry about that because that video is just perfect! of course it is not a GM or Ford factory, it's a "garage", but the very idea of it, of showing how this thing works is just sensational! I loved it, for me, this video was perfect.. very teaching, very useful, thanks a lot for making it! you're the guy!
I love how you can see the exhaust pulses move the flame around in the slow-mo shots. You can clearly see what I believe are moments of valve overlap during the intake stroke, where it's pulling the burning air/fuel mixture back into the exhaust as the two valves are open at the same time, and what appears to be a short outward flowing pulse during what I believe is the compression stroke. Most Briggs/Tecumseh/other similar small engines that I've encountered have a small bump on the back of the exhaust lobe on the camshaft to relieve some compression to make them easier for the consumer to recoil start. A common (and basically free) modification for these small engines is to grind that compression relief bump off the back of the exhaust lobe so you get full compression instead of pushing some of the mixture out the exhaust. Makes it a bit harder to start but it's a "racer" trick from older go-karting days.
Yes !
WHAAT ? is that why ? I remember last year had to clean up valves on a generator. I was very confused why the semi open positions... Really had my head messed up.... These new cheap gens have the cam vent SO close to the intake it often pulls oil in. Which in turn oils the air filter , and if the customer never checks the filter,, totally fks everything. Have you really cut that part off the cam as you say and ran it for a bit ? I imagine there are other engineering compromises manufactures might lax on when they can afford lower compression
That's fucking sweet hahahaha
@@mrsc1914 I can't speak for your engine specifically, but on an old Techumseh 8HP(from a snowblower) I had that was modified for racing use the small "relief lobe" on the exhaust side of the cam that was used to make it easier to start was ground off to allow for increased compression. it also got stronger valve springs to handle higher RPM and a bunch of other race oriented mods. The last newer generation single cylinder engine I had apart used a plastic camshaft... Pretty sure it was a briggs OHV engine from a generator that got run without oil. I couldn't believe the cam was plastic, gear and all, injection molded. insane. They don't make them like they used to.
Why did I keep squinting like I was going to get glass shrapnel in my eyes if the glass tube shattered? Haha.
Cool video.
Another great test partner. What makes these test great is that if it weren't for you doing it we'd never know what would look like. Great and thanks for your test.
The cracked glass was satisfying.
Something really makes me know the catalytic converter more details even though I use them for 20 over years. Thank You.
This is awesome! Very cool, seeing the difference in the exhaust before vs after the catalytic converter is pretty damn impressive. Also the honeycomb structure is great to watch when it glows. Thank you!
I found that very interesting as well, you can clearly see that there's no flame on one side of the catalytic oh, that really explains visually how much more fuel is being burned in the catalytic that was not burned by the engine
At first I thought the video was going to be lame but your camera at high frames made it worth watching . I have had 2 cars out of the many I have had that I gutted out the catalytic converter . Awesome video my friend .

Hey, enjoy your vids! I had an idea on my head this am and your channel came to mind. Using the phantom to show a fuel injector working at varying duty cycles. I would find it interesting to see if you could pick up the frequency in the spray pattern. It would also be neat to simulate engine rpm so the duration of injector was also indicated. Thanks for the great videos man, making youtube a better place!
Fascinating vifeo!
The reversion was very interesting. Would love to see you run an anti-reversion chamber in the same test and see if you can catch the exhaust slugs getting caught.
Been a auto technician for twenty years and always wanted to see this.
Hey Matt, a couple of future projects that I think would be really killer would be see-through drivetrain components, like automatic transmissions, torque converters, and maybe even a see-through rear end. Great video as always!
I have that in the books, it's coming pretty soon
Very interesting! I really like the videos with the see-through engine parts, they give a clear picture of what's happening inside of an engine.
Maybe it would be interesting to see a slow mo of a camshaft when the engine is revving to it's max rpm. Especially if the springs aren't good enough, to see a floating valve.
It's amazing how well this demo worked, good job! The flame at the back indicates the cat is not handling the load, though!
I'm very mechanically minded have been a mechanic. Built an high performance rx-3 station wagon way back in the day (80ish) so I was familiar with the sunrise catalytic converter.
Still was VERY impressed with the experiment. It just was so interesting to actually see it working so well.

@@remyche8768 I would disagree. carbon build up is probably from burning oil and that would explain the white smoke. Also you dont get any visible vapor while in regen. also only diesels have DPF.

Was amazing to see that thanks for figuring out a way to show it

or have a try to build a gasoline fired furnace with see thrugh cat. converter But not flame inside?

In your first attempt converter started to glow much faster even having higher mass and being attachet to big conductive piece of metal because the seals at front part of your construction ruined, letting air in. In your second attempt with the glass tube you can see that ceramics of converter glows better on the backside because exhaust pipe after converter is short and lets the air go inside.
Actually converter doesn't "like" (starts to glow better with) the richer air-fuel mixture because there's no oxigen to burn hydrocarbons. In your experiment oxigen was coming from the ambient, that's the reason of glowing better. If you run rich with long pipes and good seals, you'll see that temperature drops down in comparison with stoichiometric ratio. But if you run so rich, that there will be missfires or switch the ignition off still adding fuel you can even melt the ceramics.
So my proposition for a new see-through converter video is to make longer exhaust pipe, better seals and install a valve before converter for controllable adding of air into exhaust. Then run rich and add air.
If it will not melt down, then make revs as high as possible, and switch ignition off. All the fuel and air will reach converter and mostly burn in there. And also it would be better to load the engine.
You always come up with excellent ideas!
Not always but you are motivating me! In my mind they don't always seem so great...lbvs
This is the type of dude id would like to hang around with, great stuff man
I'm pretty sure you broke like 7 EPA laws during the production of this video...but it was worth it! Great video!
Thank you. I invented this in 1961. My grandfather owned a muffler manufacturing company. At 16, I was put to work as a machinist apprentice in the experimental shop. We had a big Chevy engine on rails, driving a generator for load. I was amazed to see the glowing pipes on the exhaust manifold.I knew enough chemistry that I thought hydrogen peroxide would convert carbon monoxide to carbon dioxide. So, how do you make hydrogen peroxide? High heat, water, and a platinum catalyst. We had all of that, except the platinum. My father was Sales Vice-President, and he dismissed my “invention” as kid’s fantasy. I think the first cats came out in 1974.
BTW: today, I think it is worth investigating the enzymes the bombardier beetle uses to produce hydrogen peroxide at ambient temperature..
That's pretty cool, you invented the catalytic converter? That's interesting I'm not familiar with the enzyme from that beetle, but I will do some research. in my opinion there has to be some way to recover all of that wasted energy going out of the tailpipe. It just seems like such a waste.
Warped Perception The leading researcher on that beetle used to be at the University of Kentucky. J
Interesting story thanks for sharing. What else have you found particularly fascinating, are you an inventor that has brought innovations to reality?
Avery I have no quarrel with that. I never reduced it to practice.
Tip: Catalytic converters "clean" themselves at high temperatures, gives you a reason to rev your car every once in a while ;) extends the lifespan of the converter and it's fun too, especially if you do a lot of "slow" city driving let her rip every now and then on the highway to clean out that hard working platinum in there
And, interestingly, catalytic converters don't really begin functioning until about 400 to 600 degrees F.
Casper Born na. I just took mine off.🖕
@@mitchellmitchell6938 Well, funnily enough, if your car is more than about 15 years old your catalytic converter is likely not working anymore anyway: Massive stresses of very high heat and vibration will eventually take their toll on it. So in that sense you might as well not even have one on your vehicle! In my state they got rid of emissions testing years and years ago so no one would even notice if I took mine off.

Inside a diesel dpf? How about inside what ever the def fluid does
dpf and def fluid ? u mixed some up there ;)
@@heinzkot360 ik they are two different things
@@VFio689 ouh okay i was just a bit confused about your comment ;)
Diesel converters use a slightly different process to trap and break down NO2 gases. The SCR system uses a base metal catalyst to save money, and a reagent containing ammonia (DEF) to facilitate the reaction.
@@Nighthawke70 im a carmechanist in germany ;) i know ... i was just convused about him using two different systems in that relation ;)
The fact that when he enriches the mixture, you see the back end of the catalyst glow red hot so soon compare to the outer edges of the catalyst shows that catalytic converters, designed with airflow/efficiency also kept in mind, din't restrict flow NEARLY as much as people think they do.
They do restrict the air significantly, but there are expensive and larger units for racing and performance needs. If the combustion chamber was designed properly, and the high load fuel trim wasn't so darn high, we wouldn't need them at all.
@@Baigle1 just swap your engine for a 12-valve Cummins diesel... no need for a cat or a muffler, haha
@@Baigle1 so you think engine engineers are designing combustion chambers wrong or do you think the EPA is putting restrictions on NOX exiting the tail pipe?
Use your brain a little
platinum catalyst is really cool. I like to play with hand warmers and its just neat how it works
Didn't think it would be that cool to see it, but it was! Amazing. Never knew it would be that interesting.
The coolest use for a catalytic converter is the Zippo hand warmers.
The catalyser heats up when you enrich the mixture is due to the higher output of unburned products which the catalytic reacts to more stable gases
a catalytic converter while it's functioning!!! that's a pretty awesome idea. I always wandered how it works while installed in the pipes or exhaust. thanks for showing us. Greetings from Argentina.
That's super awesome!!!
Maybe next one is for a see through Diesel Particulate filter, to see how it works as well!
I’ve got an idea: how viable do you thing a see through exhaust header would be on an OHV engine?
Headers get way too hot. Maybe if it's made out of glass it will survive
I will try
@@blowndome if its on this stationary engine sure, but putting glass in an engine in a car for driving is a bad idea
@Swampy it looks really Cool at night
Finally I always wanted to see how it looks, thank you!
The Tech school I went to had one that was made in the factory to learn and see how they work this guy did a great job Jerry rigging one up 👍
Great vid im in awe of the engineers that invented this.
0:32. He's using a nail for the spark plug. Nice!
Watch the see-through engine series
As crazy as you are you’re damn good at building things
🇺🇸🇺🇸🇺🇸🇺🇸
Very nice to see what is actually happening inside....Thanks
Cool experiment! I love seeing the guts of things in action!
