Exhaust smells

[Mayhem_J30]

Are there particular reasons for the different smells?

-First you have what I would call the typical exhaust smell. Not too strong, but noticeable.

-Then there's the very strong, burn the nose hairs, smells like chlorine (bleach) smell.

-Then you got the all too commen rotten egg smell, we all know this is from a bad cat.

-Then there's the B.O. smell.

I'm leaving diesel burning motors out of this.

I can only guess that the different smells come from a different combustion environments, but can a smell have a reason and then a quick diagnosis?

One cause: Dead rat in bumper. Don't laugh ... this happened to a relative of mine!

Sure Ethanol is a horrible fuel additive since you get acetone, peroxyacyl nitrates (PAN], and acetyl aldehyde when run thru a cat designed for gasoline.

My '91 Q has a smell that qualifies as:

-Then there's the very strong, burn the nose hairs, smells like chlorine (bleach) smell.

I'd be interested in a fix if there ever was/is one.

Sure change the location of the car to areas of country that don't use ethanol. [Recent addition to CA gasoline]

Mix and create your own gasoline........you can remove the ethanol [water phase method] and substitute Toluene or even MTBE or a mixture for the missing 10% voume and octane booster.

Probably not practical or just buy racing gasoline in 55 gallon drumshttp://www.osbornauto.com/racing/100locations. ... Di...te=CA

Just don't even think of using this compound:http://www.dhmo.org/facts.html

The local Costco sells that stuff. Doesn't even have a warning label on the case.

don't forget the sweet smell of C16 burning the lead and leaving those wonderfull little grayish-white deposits on your exhaust tip :-)

Just don't even think of using this compound:http://www.dhmo.org/facts.html

There is statistical evidence that this compound has been involved in some form or fashion in all deaths of human beings and animal and fish on this planet.

In the US, it appears to take about 70 years for humans ... in Japan, over 76. Some other countries appear to have way lower tolerance and die in fewer years on average.

Amazing how little the media seems to talk about it!

The local spring water delivery companies have very high concentrations of it in the bottles they deliver to home and businesses. No warning labels there either.
