So I found out how and why dieselexhast fluid works and am just wondering why cars don't have something similar.
why wouldn't a car, the thing there are trillions of , have a chemical additives to reduce the emissions the same as a diesel engine?
Get rid of some of the NOX and CO2, especially cause these engines (scooters and motorcycles in general) do emit more than a car per gallon of certain things

howdy, cars do have the same thing, it's called a catalytic converter.
lotsa miles and smiles to ya

catalytic converters do the same, yes.
I'm checking on the emissions reduced by both so I can give a better argument hold on lol
EDIT-- ok so it would be a good reducer for cold starts and would reduce emissions further than the tiny catalytic converters on bikes.
Noons has tested it probably lol, I wish I had the equipment to test it.... I would do it for all of us

I thought the fluid was used to reduce the sulfur dioxide content in diesel exhaust that isn't such a big deal with gasoline. Ever smell them? They are certainly 2 different animals

I was under that impression too, I think that is part of what it does.
But I did look it up and it reduces the nox

It does but it brings it to the levels a modern gas engine produces if I recall correctly. I wonder how environmentally friendly producing a billion plastic jugs of a new mandatory additive would be...

There's a lot of water in gasoline now (ethanol molecules attract water vapor and mingle it within the gasoline).
That causes water damp in the pistons, which condensates in the exhaust again.
That, and together with the air humidity, is why you can see so many cars having water come out of their exhaust pipe, when they're departing from a red light.
I don't know if that water affects the catalytic converter or not, though when it exits it looks quite clear.

The Ethanol in the gas adds oxygen to the final combustion process.
Gas won't burn if it doesn't have some water in it.
Combustion produces h20. Complete combustion produces only h20. Engines don't do complete combustion so there are nasty stuff coming out of the exhaust. Water is mostly found in exhaust from the combustion process.
Vented gas tanks will attract alot of water. It has to do with the evaprative pressure/temp relationship of the Ethanol. Leaving gas in a tank will gather 2 much moister in the fuel over time.

I thought gasoline had carbon in it too... Perfect combustion of pure gasoline results in carbon dioxide and water... Our atmosphere has more than just oxygen though so not possible in the real world...

howdy, the deisel exhaust fuel is held in a separate tank and used to fuel a fire hot enough to burn the particulates collected in a special filter. i'm with one of the commenters above that thinks this advancement sets us back a millennia or so. it simpley adds complexity, weight, expense and trouble with no spectacular gain. it's all political so the do gooders can claim they are doing something about the polution problem. the end game is to stop all burning of oil regardless of what affect it may have on society---i will take my rediculous thoughts and go play in the freeway---bye now
