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

@iant720 4 года назад

@@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.

@chubbysumo2230 4 года назад

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.

@jensharbers6702 4 года назад

@@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.

@johnstewart8849 4 года назад

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..

@WarpedYT 4 года назад

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.

@ron1836 Год назад

It's not supposed to be glowing underneath your car. If you ever see the case of a converter glowing hot. You have a problem! It means that it's falling apart on the inside and clogging itself up or the engine has been running too rich or burning oil for an extended period.

@Vile-Flesh Год назад

Exactly. Misfires and rich conditions rapidly deteriorate the catalyst and in come cases the valve overlap allows the engine to pull the abrasive particles from the exhaust into the cylinder and ruins the rings and cylinder walls and the engine consumes oil and runs poorer.

@ron1836 Год назад

@@Vile-Flesh yeah I could see that. I have never really thought about it or heard it mentioned before. But your right it could happen. What especially comes to mind is some engines that have pre cats, or "mini cats". They are only a foot or less away from the cylinder head. So I'm sure those would be very likely to suck those loose particles backwards. Even in this video you can see how the pressures of the exhaust flow backwards. It's almost like the engine is taking breathes. This process is used in 2 stroke engine exhausts. Where the exhaust systems shape and size is tuned specifically to help those exhaust pulses to refill the cylinder under back pressure. Also even 4 stroke engines need some type of exhaust to be able to run well. Or even run at all. Because of the same principals. Recently the exhaust fell off my old car with a 318. So the exhaust ended midway under the car. Only a few inches after the converter. No muffler, no tail pipe. The engine gained a slight bit of power. But the fuel mileage dropped ALOT. I presume this was because of loss of gasses that would linger of reburn.

@alklazaris3741 3 года назад

I once owned a car that leaked oil on the catalytic converter. Mechanic said that I was "driving a bomb" and he shouldn't "let me drive this away". Now I see why, holy crap does that sucker get hot. It's pretty impressive that it maintains its integrity under such conditions.

@wonniewarrior 4 года назад

When they first made the switch from banning Lead (Super) in Australia (1994 if I recall) to Unleaded fuel, they produced a booklet for what car could safely run on unleaded, and what 1 needed a upper cylinder lubricant sytem that metered a lubricant into the carby via a drip feed. My car at the time being LPG already ran hot and dry so it needed the super to lubricate to keep the cylinders lubricated and the rubber hoses from drying out. When the leaded became phased out, I had to get a upper cylinder lubricant system installed. It was near the radiator and ran a hose over to the vacumn line on the carby where the mechanic figuired out after the engine size and such it needed 6 drips (about 10 mls per minute) to safely lubricate. The lubricant was 1 litre and cost $15, a lot for that time. To me it reminded me of the oil added to 2 stroke fuel. And no, my car did not have a catalytic converter on it. But all cars sold or manufactured after the switch to unleaded had to have them.

Very impressive insight and slow motion. But: A catalytic converter is designed to be operating at lambda = 1, not with a fuel rich mixture! Under real conditions it is not supposed to burn unburned fuel and thereby becoming red hot. In fact, fuel in the catalytic converter will cause its premature failure.

@AuMechanic 3 года назад

Correct, CO that the cat converts to CO2 is a by-product of combustion itself and therefore is not "unburnt" fuel which is simply hydrocarbon.

One problem with using the choke to add fuel to the exhaust is that it leaves very little oxygen in the exhaust for the catalyst to combine with the excess fuel. That is why early catalyst cars (well, all through the 80s) frequently had air injection pumps that added more oxygen to the exhaust so the catalyst had something to work with to burn the excess fuel and carbon monoxide.

You haven't really shown us how CAT works when it's doing it's job, you have shown us what happens to CAT during horrific engine failure. With the second one we've also seen what effect there is on exhaust flow when gas burns in CAT/also happens when exhaust diameter is too large. The exhaust literally turns around, reverses and ruins the flow. That sends a shock wave down the exhaust which eventually starts pounding on the engine itself throwing everything off.

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.

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.

@norbertfleck812 2 года назад

@@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.

@mann_idonotreadreplies 2 года назад

COOL story bro.

@matthewcahill4475 4 года назад

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

@sentry4944 4 года назад

Well, that and, you know...lead.

@grantseuser9574 4 года назад

@@sentry4944 Lead isn't in fuel anymore and is not part of the catalyst either.

@kiloyardstare 4 года назад

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!

@willmcgo8288 4 года назад

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.

@traugdor 4 года назад

@@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.

You need to delete this video.... I can see this being required on all small engines in California by 2025 LOL

@scottmarshall6766 4 года назад

It's already happening, Small engines have had to meet CARB standards to be sold in California for some time now (it's why they no longer have carburetor adjustment screws). NY has followed suit. (I live in central NY) 4 years back I bought a new Huskvarna ZTR with a 28hp Twin B&S with a 2bbl carb. The 1st year I had to rebuild the carb, and again in the 2nd year, (surging. but couldn't richen up a tad as it needed) then I bought a whole new Chinese Carb for $48 from ebay, $2 less than the Briggs rebuild kit. Runs better than it ever did, and gets MUCH better mileage (a very real concern when mowing 15 acres/week). I have no doubt the new carb is polluting less, and it saves me about $20/week in fuel costs. Sad state of affairs.

@Baigle1 4 года назад

@@scottmarshall6766 If modern engines burned the fuel more efficiently, we would not need catalytic converters (still nice to have with proper design to reduce exhaust restriction). Jet engines (commercial HBTs) have stricter emissions, and don't need cats. They also get way better TSFC efficiency due to them being smart, unlike auto manufacturers. Get rid of all the EPA required stuff, and do it right. I can't find the information right now, due to the annoyingly complex wording and difficulty finding the actual EPA regulated numbers (Tier 6 regulations, etc), but I'm pretty sure that commercial HBTs and gas powerplant turbine generators put out way less NOx and burn more efficiently than a higher end high-mpg passenger vehicle. Even with the bolt-on junk like catalytic converters, PCV, & EGR.

@83hjf 4 года назад

@@Baigle1 those engines are run in a specific RPM and load curve. they are run in their highest performing point, or shut down. a car needs to be run in whatever the environment demands. a jet engine is incredibly inefficient during takeoff and landing, but super efficient during flight. car engines are already as efficient as they can be. the only truly efficient engine, at any load, is an ESC controlled electric motor.

@cyancoyote7366 4 года назад

There's actually not a whole lot of optimization that can be done on today's engines. I support putting stricter and stricter rules regarding emissions until fossil fuel based engines can be phased out entirely.

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 -.

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.

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.
