Just finished an LS swap and had no problem adding a "High Flow CAT", operates as originally designed for the donor vehicle. Still get amazing performance, win / win. Good video, learned a lot, and you stuck to engineering NOT propaganda, thanks.
Your video combined with your explanations make the working principles of catalytic converters easy to understand. Thank you. I was hoping you would discuss some of the dos and don'ts for enthusiastic car owners, for example, the effects of the use of fuel additives or catalytic converter cleaning agents and if they do or do not affect the functioning of the catalyst. Thank you indeed for the taking out time to educate us on this important component in our cars.
To better help with understanding how the Regen works on diesel engines, if the ecu detects the dpf filter getting clogged, it triggers a injector that’s placed in the exhaust after the turbo to inject raw diesel fuel into the exhaust. The raw fuel reacts with the DOC and exhaust temperatures go up pass 1200degrees to burn off soot in the filter and turn it into ash which settles at the bottom of the filter and must be cleaned at prescribed intervals. Also if the truck is driving and the exhaust temperatures are already hot enough it will actively burn off the soot in the DPF which is called active regen.
Or some cars (most cars?) use the existing injectors + glowplugs (rather than having an extra one) to inject extra post-combustion fuel and heat. Explained here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Q4aI0-xIQsc.html
I don’t remember PCV systems before 1968. The cars we had before 1968 were, 1960 Corvair, 1961 Impala, 1964 Impala and 1966 Chevelle. None of these had PCV valves. We had a 1968 Camaro and 1968 Impala and I think these had PCV valves. I remember that the California reguilations started in 1967 with the PCV valves and then in 1968 for the rest of the states. This was the time I started driving cars. My first unleaded car was a 1971 Vega, it ran so poorly on unleaded gas, that after paying $0.41 per gallon, I switched to regular leaded fuel at $0.25 per gallon and the car ran beautifully. My last new car than ran on leaded fuel was a 1974 Nova (straight 6 cylinder) and it ran perfect. PS: cars seemed to get better as the years ran by. When I started driving Japanese cars, mainly Hondas, in the mid 90’s, I worked less on them and drove them more.
It's very helpful... it shows that the catalytic system does not work. ....And there is a need for more engineering to make the system work and maintenance to clean hence 'filter'.
Why don't they add the urea stuff to the fuel in the filling station? Seems like that would make more sense. Unless there is some detail I don't know about.
Urea is very corrosive, too, and I don't think it dissolves well into fuel. Also, it sounds like the diesel filters use the water the DEF urea is dissolved in to be part of the catalysis/consumption process, so dissolving urea in distilled water is likely better as a combination because people would need to add ONLY water regularly, which they almost surely wouldn't do. Plus we often just use tap water, and I wonder what effect 'a bit of iron in your tap water' would have on the DEF equipment...I bet it would make a mess of things. Hard water, soft water, all a bad idea so we'd have to use pure distilled water...but 95% of people would slap tap water into the tank and call it good enough, then they'd just b***h that they have to replace their catalytic converter/DPF/whatever "every twenty thousand miles and that's the technology's fault, not theirs for using tap water!" So, DEF using distilled water as its carrier is likely the best combination of things to minimize annoyance, rust, or engine failures overall.
one of the reasons maybe the absorbant in a submarine works fine with a slow air current while in a car, the exhaust gas flow can overwhelm the scrubber impeding free flow which knocks the exhaust back in the systemb into combustion chambers.
How about the long octopus air intake systems added to engines today? Why every car doesn't have a functioning hood scoop to suck cool air straight directly into the motor (via air filter naturally) is completely beyond me!
If CO2 is one of the final product to come out from the catalytic converter, why don't you install a scruber-like device in the outlet part which is used in submarines in order to reduce if not eliminate CO2?
Actually soon there is a reverse enineering of combustion action by twin cycynder like 6 become 12 and one action of combustion cycynder is couple with a twin work in reverse action so fuel less may exten fuel tank to few thousand miles
How about just a vapor fuel system to mix the fuel out of vapor level instead of droplets and increase efficiency reduce emissions and improved performance along with engine life
Gasoline engines can and do clog catalytic converters. Contributing factors are; -poor fuel quality Ethanol does NOT increase fuel quantity. -Low RPMs hinder emissions performance When a clog forms in the ceramic structure one of two things will happen as pressure will buildup. -The clog blows out -The ceramic structure will blow out with the clog When the clogs goes by it’s self it isn’t very noticeable. But It mostly only opens partially and a (420) performance code will trip. When the ceramic structure goes it will trip a performance code (420) “IF” the ceramic structure is intact it can be unclogged by cleaning to restore performance, thus resetting the (420) performance code can be reset. I clean mine about once a year by adding a quart of lacquer thinned when my tank has only 2 or 3 gallons in it, near empty. I do this near a highway so I can drive with overdrive OFF at highway speed. In 10 miles any clog formed will be resolved. Drive it longer to clear it more. If it’s the first time ever done; Add two (2) quarts or more into a quarter tank of gas approximately five (5) gallons and drive it more. Take a fuel can with you until you gain confidence. As many people “think” their car could have trouble with running lacquer thinner through the fuel system. I don’t wait for a (420) performance code. I’ve done this for years now and my scanner shows me performance improvements every time. Preventive maintenance does eliminate costly replacements…
Exhaust gas recirculation does not do as advertised here. It’s mixing dirty air back in the combustion chambers in theory reburning to reduce pollutants by looping it through the system. What really happens is by looping the dirty air it creates more dirty air in the cylinder as in a snowball type effect. Rebreather systems help’s scuba divers but it’s not as good as fresh air. Find a way to feed it into the exhaust manifold not the intake. Even with a check valve pressure’s won’t allow it to enter back into the exhaust manifold. Sooo It makes exhaust worse NOT better. If anything install more cat-cons after the first in-line in-order to reduce pollutants. A multi step approach, rather then recirculating…
Most catalytic converters on cars nowadays are kind of designed to unless there's a problem with them not reduced performance in any way because reduced performance is reduced fuel mileage. So they've made them flow well enough. That in less there's an issue with them. Typically, you don't gain any performance by removing them.
With the amount of engineering, innovation and science put into modern exhaust systems, I'm beginning to think that, "upgrading" my cars exhaust to be faster and LOUDER, Might be the most ignorant and straight up disrespectful change I could possibly make to the car. Lol. Still might do it though.. For I am, a jerk. :)
The newer cars already have good exhaust filtering systems, its the politic and the politicians that are pushing the EV for their own benefit, in ten years from now used batteries will pollute the earth more rapidly than the ICE

No shit? Which are your specialized education degree in internal combustion engines? How many hundred of engines did you upgraded as own build in your garage?😂
@@blackericdenice Are you drunk? We are talking about REMAPS/tune, OR effects of a RESTRICTION on exhaust? Yes i do not make bullshit tune, i do only for my dta from the race car and no very often for few oem ecu's, BUT you just switched from my question to another domain, as was about a HARDWARE DEVICE affecting (or not) how the engine runs.
This has to be the dumbest comment on the internet. You do know that literally everything you consume is delivered by diesel right? Your food is farmed using diesel, moved on diesel trains, delivered to the store using diesel trucks. Do us all a favor and please don't vote. Just stay home and drink your Brawndo.
When much of the information in this presentation was accurate some was not. Removal of the catalytic converter is illegal. The horsepower gain is not noticable and the noise emissions, loud exhaust, is a dead give away that you are breaking the law. Fines are incredibly expensive and the catalytic converter will have to be put back in any case. Today's computer controlled emissions systems are incredibly efficient. Super cars like the Chevrolet Corvette and the Dodge Demon produce in excess of 1000 horsepower and pass the strictest emissions standards right off the showroom floor. Any modifications will only produce more noise and draw the attention of police and cost very high fines. I'm retired from the automotive industry after 45 years of working professionally. When I started there were no such thing as emissions laws or computer controlled engine management. Today you can buy a high performance car that can produce far in excess of 1000 horsepower and pass strict emissions standards all due to computer controlled engine management. In fact, the "clean air act" can be detected in the ice core samples of ice samples taken in different regions of the world. In my lifetime I have personally seen the improvements in efficiency of our cars and the resulting clean air quality in our country. It is greatly important that all countries do the same to improve world air quality. Tampering to attempt to improve performance is nothing more than meddling and improvement is highly unlikely and not recommended. People that deliberately turn up diesel fuel delivery to cause huge amounts of black smoke, rolling coal, are damaging their engines to attract attention like petulant children. Law enforcement will be extremely expensive and may result cause higher insurance premiums and other negative effects.
How it works is new car buyers are forced to pay thousands more, while people who can afford only older, used cars must spend thousands on platinum and palladium -- or give up car ownership -- when their perfectly good cars fail smog. Great scam! Exactly who owns the platinum and palladium mines, anyway?
