Engine research
The basic research for all engines: it does not make any ship faster by itself, but it unlocks the rocket, diffusion and warp engines.

Role
Engine research is purely a requirement. You need level 2 for the Rocket engine, level 6 for the Diffusion engine and level 8 for the Warp engine (plus a Research lab at level 8). Your ships only get faster through their engine research, not through Engine research itself.
You need level 2 right at the start for the Rocket engine and therefore for your first ships. Level 6 becomes interesting with recyclers and starcruisers, level 8 with the big warp ships such as Battleship and Destroyer.
Plan Engine research together with your Research lab: for the Warp engine, both have to reach level 8.
Background
Engine research is used for the further development of engines. The greater the level of engine research, the more efficient the engines will be. There are three types of engines: rocket engines for small ships, diffusion engines for fast ships and warp engines for larger ships.
