go start your car in a closed garage and tell us how clean they are.
It's a slow way to go nowadays.

Back in the 90's I read a story about Volvo pollution control technology - they tested one of their cars in Houston and the tailpipe emissions were actually cleaner than the air in the intake tract.

That's right - driving a new Volvo in Houston 30 years ago actually filtered and cleaned the air. :LOL:

I'd be interested in the chemistry behind that claim.

It was 30 fucking years ago - like I have the article right to hand.

Believe what you want - you will anyway.

Easy there, Sloop.

My thoughts go to carbon oxide emissions. The air going in for combustion cannot have MORE COx than the exhaust gas, if you are burning carbonaceous material. It just can't. Not unless there is some sort of sequestration process to capture COx from the exhaust.

Now, if they are examining OTHER pollutants, perhaps. That's why I said I'd be interested in the chemistry. Not a dig at you or your truthiness.

The engine was probably pulling oxidized metallic salts out of the air and dissolving them into the engine's lube oil.

It was probably NOx - IIRC that's the most toxic component. The fuel also contains a bunch of stuff that converts as well - exhaust is a lot more than the leftover intake air.

My memory ain't what it was, but I believe it was about SMOG causing pollutants.
