How does an exhaust catalytic converter work?

[@ivanthebelow-average2192]

It also serves an alternate function: It works as a source of income for anyone with a hacksaw

[@gimpygardner3377]

And your mechanic also makes money. That's 2 people employed. Cats save the environment and the economy!!

[@Автомобилнидейности]

The catalytic converter work by blocking the horsepower

[@AhrkFinTey]

yeah by like 0.5%

[@alexwithanx]

@@AhrkFinTey By a bit more than that, but since most vehicles are set up for a certain setup, like having a kat in them, it will probably make you lose hp/torque if you remove it without remapping the ecu. On bikes for example it can really screw with the engine and make it run much much fatter. However removing it then remapping can give up to 5-10% HP gain.

[@ALittleBitOfGay]

@@alexwithanxmodern cats flow incredibly well, and this isn’t really true anymore. Way back in the day catalytic converters hurt performance a lot more than they do now. There is really very little reason to not run a cat on a car now, unless you are doing proper race car things (like running high zinc content oil, anti-lag/2 step all the time, etc. all of which you really won’t be doing with a street car)

[@mohamedyusufmohamud8193]

the downside of this technology is that over time , the catalytic converter will be useless due to the deactivation of the active precious metal to avoid this we can develop a regeneration system for the active catalyst which enables them to self-regeneration after it is used for long time.

[@kevinbrown1368]

catalytic converters are designed, developed and tested to last the full useful life of the vehicle and overwhelmingly the original OE converters are still in place when vehicles are recycled . In fact, the precious metal containing catalytic converters are typically the first parts removed from a vehicle when it enters a automotive recycling facility and are recycled into new catalytic converters.

[@pierpaoloscian5926]

Well if it's a catalyst I don't get how it would be consumed overtime. As everybody has studied in chemistry class, a catalyst doesn't get used up, since it's not a reagent. It only allows a chemical reaction to undergo faster, without adding products or changing the equilibrium constant

[@kevinbrown1368]

@@pierpaoloscian5926 an engine, especially an old one or one that is passing unburnt fuel can poison or reduce the surface area of the ceramic support used in the converter. This is why lead and zinc additives were eliminated or reduced as well as fuel sulfur which has been reduced to well below 10 ppm. Unburnt lubricant which contains phosphorus, magnesium, etc can also poison the converter. But as I said previously, overwhelmingly, converters on modern cars last longer than the car itself.

[@mohamedyusufmohamud8193]

@@pierpaoloscian5926 Thanks, your reply to this matter. you are right as we studied in school the job of the catalyst is only to accelerate the chemical reaction. but, let me explain to you what I mean by catalyst deactivation, for example, in water purification we use filters and membranes, over time what will happen to the filters, all the particles in the polluted water will accumulate in the pores of the filter. so we have either change the filter or we have to clean it. so as the catalytic converter precious metals pt or Pd which are the active site and responsible for the conversion of toxic CO to CO2. when it is used for a long time it will lose reactivity by accumulating carbon and causing deactivation. so it needs the filters either regenerate or change it. that is what I am talking about .

[@Wildminecraftwolf]

@@mohamedyusufmohamud8193 No precious metals dont reduce in reactivity in the process as they are not consumed in the reaction as they are in other kinds of filtration reactions.

I am not a chemist neither an engineer, I am a technician ( Grease monkey)and I work on cars for many years, what I’ve seen over the years (some cases)broken cats from inside making rattle noises, melted ones from overheating due to engine misfiring pushing raw fuel through the exhaust along with all other emissions that burned in the catalyst, some cases head gasket or intake plenum gasket failure caused internal antifreeze (cooling system)leak into exhaust system through valve’s then trapped inside catalyst
