But for the older technology, they used External Combustion Engines. It is far lower efficiency than internal combustion engines. The steam engine in old-style trains and steam boats are the best example of ECE (External Combustion Engines). The most of fuel that used in ECE is coal. The coal is burned to create the steam, and the high pressure of steam compressed and it create a motion in the engine. As we known gasoline and diesel are the basic fuel for Internal Combustion Engine.
