Here's why:
* External Combustion: The fuel is burned outside the engine, in a separate chamber called a boiler. The heat from the burning fuel turns water into steam, which then drives the engine.
* Internal Combustion: In contrast, internal combustion engines, like gasoline engines, burn fuel directly inside the engine cylinders.
Here's a simple breakdown:
* Steam engine: Fuel (wood, coal, oil) -> Boiler -> Steam -> Engine -> Power
* Internal combustion engine: Fuel (gasoline, diesel) -> Inside engine cylinder -> Combustion -> Power
