What causes black smoke coming from the exhaust pipe?

This usually means the valve guides or seals are bad, or possibly a cracked ring, which would allow oil to get into the combustion chamber. An engine that is running rich will generally have black exhaust. If there is oil getting in the combustion chamber, the smoke will be bluish.

If it looks by your exhaust pipe like you have a diesel engine, but you don’t – then it is really time to check the air-fuel mixture. High carbon monoxide content

Why does combustion take place outside the exhaust pipe?

Combustion does not take place near cold cylinder walls. That partial combustion gets deposited in the exhaust pipe. If the deposits are really thick and coating everything even outside the exhaust pipe then you probably have a fueling or timing problem that needs fixed.
