Cheapest way to make a cooling chamber?

It DOES make a difference, dingledorf. That is WHY pollution controls were adopted and WHY gasoline got reduced in octane and WHY engines were made more efficient, as opposed to the muscle car era where they were overboard for power at the expense of combustion completion.

You are clueless.

ecadence.org:

modern engines run closed loop

octane reduced? if anything it has been increased to take advantage of the improved efficiency of higher compression in modern engines

The muscle car era was the sledge hammer approach, make it bigger instead of better. They had giant inefficient carbureted engines

Not remotely true; pollution controls date back to episodes like the black fog in London (killed thousands).

and the problem wasn't air depletion, it was excessive... contaminants.

CO poisoning causes your blood to pass less oxygen to your cells, it doesn't matter how much oxygen is in the air if it doesn't interact with normal hemoglobin and become oxygen available to power your brain.

You can live on oxygen partial pressures of 2 psi (like La Paz, Bolivia) or the sealevel normal 3 psi. But breathe CO at 0.001 psi concentrations, and everything goes dark.

I know what the process is. You are the third ditz to bark your mini primer and it was never needed.

And the pollution controls I referred to were the automotive controls the US feds put in place to make car makers here put systems in place to reduce emissions.

Not some towering smoke stack thing.

in large industrial systems they use a compressor and pure ammonia as the working fluid

You've snipped enough to obscure the fact that I talking about oxygen levels in a garage containing a car wit it's engine running.

completion.

None of that is remotely true. Pollution controls don't have anything to do with oxygen levels in the atmosphere and everything to do with minimising pollutants coming out of the car engine. Incomplete combustion means more pollutants.

Quite why you obsess about oxygen levels escapes me. It's lunacy.

You may find this conclusion appealing, but in reality it you who is clueless.

DLUNU is fond of his own errors, and isn't going to let anybody striaghten out his thinking.

What matters is the crap in the air you breath, not where the crap comes from.

The black fog that killed about 4000 Londoners in 1952 was mostly generated by coal being burnt in domestic fire-places - which have chimneys, not towering smoke stacks. Power stations, even then, burnt their coal more completely.

You haven't been allowed to burn coal in domestic fireplaces in "smokeless zones" in England since then, which is to say, big cities.

Places like Southampton, Brighton and Cambridge weren't big enough to qualify.
