what is carbon build up

[FrankieJames7]

so what asking is, is carbon build up, whether in an engine, on a frying pan, or in the oven elemental carbon, C? or is it molecules of compounds?

well captain derp there are many allotropes of carbon. a diamond is carbon, so is graphite

That’s correct

so what kind of carbon builds up in an engine or on a frying pan?

The carbon kind.

Good talk.

I've learned so much from today's science lesson.

Hydrocarbon buildup is when you huff too much gasoline vapour into your lungs Frankie.  Which is about every day for you.

Carbon buildup is what majority of this forum has from lack of sex. Leads to quick tempers here

why are you mad faggot? cant jerk off to the queen and drink tea anymore?

[frenchy]

carbon buildup is the buildup of carbon.

If you stop assaulting women and using meth, carbon will not be an issue. Ladyboyfaggot.

So is there a difference between frying pan carbon and engine carbon? How about “lack of sex” carbon?  Can I treat that with a fuel additive from Napa?

This was actually one of the most bestest and knowledge laden threads here lately!!!

Carbon deposits in an engine come from incomplete combustion.  The carbon comes from the hydrocarbon fuel source.  There are different numbers of carbon and hydrogen atoms depending on the fuel source.  Some fuels are carbon heavy like coal, compared to say natural gas.

Here is a example of a natural gas combustion equation.  In this case all the fuel and oxygen gets converted to CO2 and water.

2C8H18 + 25O2 --> 18CO2 + 16H20

The problem is no engine runs at the exact stoichiometric ratios.  Below is an example when there is a rich condition, too much fuel and not enough air.

Eg: 4CH4 + 5O2 --> 2CO + 8H2O + 2C

The 2C is just elemental carbon.  Most of the carbon will go out the exhaust.  Some gets deposited on the components in the combustion chamber (head, piston, valves).  A lot of it actually ends up in the crankcase oil.  It's why your oil turns black.  Soot is basically just carbon.

I knew taking a combustion class with the toughest professor in the department would pay off.

Here is a good explanation.  https://lchs.lpsd.ca/eteacher_download/2112/34962

Carbon deposits are one of the reasons virtually all fuels and oils have detergents.

so all the black stuff on a valve is C2? id imagine that stuck on soot changes with continued exposure to fuel, air, heat, and exhaust

Its just C, carbon.  2C means 2 mol of carbon.  C2 would be two carbon atoms bonded together.  I'm not sure if that would even be stable or naturally occurring.  Actually, just looked it up, it isn't stable.  https://en.wikipedia.org/wiki/Diatomic_carbon
