Game Info[]
The Combustion technology creates the contemporary internal combustion engine, widely used in smaller transportation vehicles.
Its military application allows the creation of the Destroyer, as well as the first Armored units in the game: either the World War II Tank (or the Landship in Gods & Kings 
and Brave New World 
). This will usher in the dominance of 
Oil and make the mounted units (those requiring 
) obsolete.
Finally, in Brave New World, land trade routes benefit from extended range with this tech (possibly from the use of cars and trucks).
Civilopedia entry[]
"Combustion" means burning. It's a chemical reaction between substances, one of which is usually oxygen, which often results in the generation of light and heat energy. Here we're speaking specifically about the use of combustion inside of an engine (hence, "internal combustion") to create energy to turn a crank or move a piston.
There are two different types of internal combustion engines: intermittent-combustion engines and steady flow engines. In an intermittent-combustion engine, a certain amount of fuel and oxygen is injected into the combustion chamber where it ignites and moves a piston or some other mechanical device, after which another discrete amount of fuel and oxygen is once again inserted, and the entire process repeats. Automobile engines are examples of intermittent-combustion engines. In an steady-flow engine, a steady stream of fuel and oxygen is injected into engine, burning continuously. Jet engines are steady-flow.
The first internal combustion engine patent was given to Englishmen Samuel Brown in 1823 for his "gas vacuum engine," which ran on hydrogen and oxygen. The first patent for using a jet engine to power an aircraft was filed in 1921 by Frenchman Maxime Guillaume. Neither of these first attempts was very successful, but they paved the way for technologies which would power the world right up until today, and for the foreseeable future.
