This would depend on your nose. A bad CMP sensor may cause improper burning of the fuel and can give a smell out the tailpipe. Will the CMP smell? Never. A Ford camshaft syncronizer will squeek and could cause a metallic burning smell.
If your talking about cars... If you smell a burning smell, or your red battery light comes on then i would get your alternator checked out!

head gaskets are probably bad and leaking oil onto crossover pipe .
Bad heater core.

Your vagina is supposed to have a scent: it should smell musky but clean and will change with hormonal changes throughout your menstrual cycle and when aroused. As long as it doesn't smell bad it's not a problem, but a bad odour such as a fishy smell or a smell like bread can be a sign of a temporary imbalance in flora or a full-blown vaginal infection. Itching and burning are common during a yeast infection, but bad odour alone is a sign of an issue so see your doctor if you experience this.
heater core is bad may need a coolant flush
Electrical fire or bad bearings. The alternator is probably toast. Buy a new one.
Well i don't. I think the real question is why do yousmell burning feathers. I can't even imagine what burning feathers smell like.It smells terrible, I regularly smell burning feathers, paint, and a strong perfume or potpourri that nobody else around me can smell.
because you are exercising and all that sweat that comes from body fat that you are burning tends to smells pretty bad.
