In-game description:
"Basic propulsion technology for smaller vessels.
The oldest type of engine. Gases are ignited within a chamber and forced out an exhaust creating thrust in the opposite direction. Combustion engine technology has low efficiency, but it is a cheap and simple option which is well suited for small ships. Every level of research provides a 10% increase to ship speed.
The following ship types use combustion drives: Small Cargo Ship, Large Cargo Ship, Light Fighter, Spy Probe and Recovery Vessel."
