And for someone, acetone, ammonia and, oh God, hydrogen sulfide, are beaten in the nose! The most interesting thing is that everyone is right.
When they came up with the so-called triple action neutralizer, the attention of the developers was attracted by the three main hazards contained in the exhaust gases: CO, CHX and NO2. The entire filling was calculated to suppress them, stimulating the oxidation reactions using a platinum or palladium coating. It’s just that complex aromatic hydrocarbons and impurities contained in gasoline fell out of sight (do not forget about additives that increase the octane number!).
And they, too, enter into the neutralizer in the reaction - sometimes with unpredictable results. The result is a far from harmless bouquet. Moreover, there is an opinion that a car with a converter is even … more harmful than the old ones. There, they say, there were only "crude" poisons that poison here and now, and now there are more carcinogens that kill "tomorrow and the day after tomorrow." The solution is seen in the transition from fossil fuels to synthetic, derived from natural gas or organic raw materials. It will only have what the motor needs for efficient operation, and nothing more, such as sulfur.
