@EngineeringExplained Your videos have helped me so much. I started watching your videos a couple days ago and am almost done with them all. I am currently a sophomore in mechanical engineering and have always liked cars. Your videos have made me want to explore cars more in-depth. Thanks again!
Great, thanks for watching! Seriously 100+ videos in a few days? Maybe time for a nap.
This is a great video man. Needed to learn how they worked fast and this helped so much. Thank you.

It's the carbon in the exhaust, which hasn't been filtered out. Modern diesels typically will have DPFs (diesel particulate filters) which will almost eliminate this.
Great explanation. I've seen inside a catalytic converter, and have always been curious as to how it works exactly.
Oxygen alone is fairly dangerous so this isn't too common to do. It's safer to use it as a molecule with N2O which keeps the oxygen from igniting until it has split from the two nitrogen atoms.
I'm watching all your videos for years now. But every time I re watch them ,I learn more stuff then previous time. :))
Excellent video on the chemical interaction with the catalyst + the two types of catalysts in a converter. I love watching your videos! Thanks for sharing.
Great to hear! Some of it is still a little voodoo to me. I don't fully understand the attraction between the catalyst and the molecules. Obviously it has to do with the electron cloud; but I don't enjoy chemistry enough to continue to dive deeper.
I know this is 10 years old. Love coming across this content. Fantastic. Nice to witness smart, well educated young people on the internet. Great job young man! Excellent presentation. It would be interesting to know what you are doing with your career and education these days. Thank you
great videos ..very helpful during exams. THANK YOU
Glad the video quality and explanations improved over time.
Good job man, I've been looking for videos like this. Super helpful
Downforce, for higher cornering speeds/traction. Check out my video "front wing" which goes into a bit of detail of aero in F1 racing.
You may be interested in my videos on rotational inertia. Aside from that I don't have much to say about rims.
Thousands of tiny little ducks, you say....
Simplest (smartest) description I have found...
Typically they last the life of the vehicle, but you'll know upon your car inspection whether or not. If you do have to replace it, it can be as simple as unbolting and putting the new one in; sometimes it will require some welding.
Thank You,this helped me on my science C1 Exam
I've got a video on KERS, regen braking pending. I also do want to do a video on the new F1 engines eventually.
I was looking for videos like yours. thank you, these are going to help me learn.
Thanks much! That was well explained and not excessively complicated. Cheers
I will be making a video on O2 sensors, yes!
Your videos are far better than that guy who thinks he's a comedian. I appreciate presentations that get straight to the point.
This is why I love your channel. extremely simple to understand how cats work. What's the connection to the need for an operating temperature?
Yes, sounds good, best of luck!
It's a mix with the other elements I mentioned.
I found this to be simplified in a good way, yet very informative. Simplified explanation goes a long way in theory retention. Do you have anything on EGR cooler and it’s function? Thanks 😊
Well done. Nice explanation, overview and graphics. Basic stuff, but what I needed. I think it would help to have taken basic chemistry to appreciate and absorb the information presented. As far as I can tell the chemistry is spot on but simplified. Thanks!
This is probably how dragons breathe fire

this is an underrated comment
Thanks for this clearly explanation. You did help me a lot .
Well hopefully this video illustrated the reason. If the water condenses (water is a product of combustion) you may see it drip out the back of the exhaust.
Excellent! Good job. Thanks for a great explanation.
I'm mostly interested in the way it steered.. I was really amazed after I saw some behind the scenes stuff with the car going sideways and stuff!
Explained really well. Easy to understand :)
Basically it's much easier for the chemical reactions described in the video to occur when the system is at a higher temperature.
The engine block itself shouldn't be getting that ridiculously hot, as it has ports flowing through with coolant that try to keep the temperature somewhere around 200 degrees F (coolant temp). So I don't think water getting on the block would be a huge concern (obviously it happens when it rains or you dive through a puddle. That said, I wouldn't simply dump a bucket of water in it; and driving through deep water can cause countless problems.
Should be awesome that you can post videos on Twin Charge systems like in VAG, or Launch control, or MSD ignition systems, or variable geometry turbos, or KERS, or Regenerative Braking.... also if you can talk about the new regulations for F1 next year on turbo engines... Nice Channel keep up the good work!
I believe they all use the same basic set-up; the high-flow ones just have more area to pass through.
Yep, I believe that's true.
Great explaination! Thanks a lot...
this is a good explanation, now I m clear about it.
Great video, I haven't been able to find a single other explanation of cats other than that they burn off the harmful gases. Which raised way more questions than answers for me. Thank you for going into just a little bit of detail so I can understand the core principles of how these things worked. Everybody else just made it sound like Voodoo.
Great explanation!
The air you're breathing is 78% nitrogen.
Could you please make a video on fuel maps and ECU programms
Many thanks for this video.
excelent video buddy, thanks for the knowledge
Emo phase of engineering explained! Still love it! And ... That whiteboard never gets old😂
thanks for your explanation
Interesting, perhaps to aid in burning off any excess fuel.
Unbolt it, and yes, it could. You should leave it in as most states require one legally.
We're covering hydrocarbons in Chemistry again, and that oxidation/combustion equation does come up. Neat.
Rich a/f mixture.
Certainly both technologies need to evolve and improve over time; catalytic converters are not 100% efficient, so keeping the engine efficient is important too. Also, catalytic converters cannot eliminate CO2.
Thanks for the episode! I have a new car model (about 2017) working on diesel and a semi-open garage (I mean there is a ceiling that covers two-thirds of the car but not all the car, three walls but there is no door in the entry, and instead 2,5 meters of fresh air). Can carbon monoxide still be dangerous if the car's motor remains on, or is it safe even if I forget to put it off and stay inside the garage??
Thank you for explaining this :)
Assuming it's the most restrictive part, yes (not necessarily true). Though it's illegal in most states, and should be kept on.
how often do the inner plates need soot cleaning?
I've been a partner for over a year. In fact, anyone can be a partner now; but I applied before April of 2012 where you still had to be accepted into the program.
Cool, I'm only 14 and I feel like I could explain a whole car and put one together your awesome😄!
It can cause back pressure, hence the creation of high-flow cats.
Tal vez un dia!
Do you have a video on the O2 sensor that's before and after the Cat? If not can you make one? I do have an idea from their name but to know exactly how they work and sync with other parts would be nice. Thanks for another great video, please keep it up. Learning a lot!
I learnt so much in less than 5 minutes. why can't all science be taught like this?

thanks for the explanation. are any companies looking to do co2 capture in addition to catalytic converters?
thnx, explained pretty well for my gcse chem although is there a difference between cataysts for the cracking process and the converter? thnx again (:
Thanks bro the video was really useful👌
thank you for this, amigo
Thank you man, srsly this was the only video that helped me with the homework, you are a superhero
thanks for the great video as always!
Great video
This is why if you are failing your vehicle inspection due to emissions they will sometimes tell you to go for a long drive then try again, because the catalytic converter will be more efficient once it has warmed up due to you driving it around a lot

is this why a lot of exhausts on a healthy car can be a little smoky on cold start-up?
Awesome lacture
Hi Jason, What are the benefits of having two catalytic converters in a car? Is it to increase longevity of the catalytic converters or to increase efficiency of the catalytic converters?
Not positive, I assume they just have a greater area for the exhaust to pass through.
Can you explain how to calculate the unburned fuel in the exhaust? I've watched your O2 sensor and exhaust videos and don't see that detail... Specifically I'm looking to find out how much of the fuel was not burned in the engine (pre cat). I'm certain there is some way by using the CO and CxHx. Can you help me or point me in a direction where I can find the answer?
I really like all your videos , Quick question since you own or once own a an acura integra you might help me I change my Integra's Cat about a week ago everything works fine the check engine light went out for a weeks yesterday i smell this "rotten egg" smell again , check engine light went on again...I have a feeling its my catalytic converter again is there any reason why my Catalytic broke down if it is the main reason?
very informative!
Great video really well explained. Thank you very much :-)
thanks, great video.
Hi. Would you agree that the stuff entering the catalytic converter is on some level still could be called by name fuel? Does not matter what grade but would it be in your world a fuel?
Thank you for your videos man
Does lacquer thinner in gas tank can clean the catalytic converter without damage to the hoses or rubber components? I have the code P0420 on my 2001 Chevy Monte Carlo
Good info
Which converter contains platinum mostly ? Petrol or Diesel ? After purchase from the scraps, precious metals existing in there or not ?
It is India. We are still in Euro 3 standard. They say it is one of the features of Euro 3. I have heard someone saying that the oxygen provision is merely to dilute the exhaust gases so that there will be less harmful gases per unit volume. So it does not help to reduce harmful gases instead it just fools around. But I think it does some job of burning the exess fuel as you said.
I didn't know that it was, interesting.
Hey man any chance you do a video on magnetic suspension? or the way the formula-like car in fast 6 works? thanks!
I'd like to understand a few of the Porsche technologies. Rear Wheel Steering, Dynamic Vectoring, etc.
nice i understant everything
You are awesome!
At 1:23 you said the nitric oxide bonds weren't as strong as the bonds with oxygen and the catalysts. What exactly do you mean by this? I know the electronegativity can't be as high in those bonds so what physical mechanisms are occurring that cause this? I've taken a couple of college level chemistry courses and I'm about to take organic chem. What you spoke about here is what we are about to go over in class and I was hoping you could give me a good explanation of a real life example. Thank you and you do have amazing videos.
Great video, just wondering though: Would there be any reason you couldn't use the same catalytic converter indefinitely?

They last for a good while, but if carbon were to build up it would at least need to be cleaned.
