What is the difference between internal and external combustion?

Question

and examples of each please

Answer 1

Internal combustion is when the fuel is burned in the cylinder or vessel from which work is extracted; a gasoline or Diesel engine, as in your automobile is an example. External combustion is when the fuel is burned in a separate chamber, such as in an old steam locomotive or in a fossil-fuel-fired power plant, and the heat is taken up by steam to run into the device from which work is extracted.

Answer 2

a cars motor is an internal combustion engine, because the combustion is contained within (internally) the chamber of the cylinder (the energy of the combustion being harnessed as kinetic energy when the piston is forced down, and the excess smoke and ashen residue becoming a controlled flow that exits via the exhaust)
dont know much about external combustion

Answer 3

Internal combustion is what happens to your stomache after eating grandma's homemade peanut-butter. External combustion is your sphincter exhaling.

Answer 4

Internal combustion engines exist. External combustion engines don't exist unless you might consider jets to be external combustion engines.
Internal combustion engines draw if air/fuel mix by vacuum, both valves closed, compress the mix, add a spark to explode the mix which pushes piston back down, both valves closed. Exhaust valve starts to open as piston starts back up to push burnt gasses out. That's kind of it in a nutshell.
4 stroke engine cycle--intake stroke (down), compression stroke (up), firing stroke (down), exhaust stroke (up).

Answer 5

The same difference applies between doing your own work and cheating.
