Engines are fitted to ships to power movement (it isn't possible to construct a ship without an engine). The maximum speed a fleet can travel is determined by the slowest engine in the fleet.
They can function without fuel (olzine), but provide greater speeds while using it. Each civilization starts with a single engine: Base Warp Engine. Additional engines can be unlocked by researching the relevant technology.
Engines also provide ships with energy, which certain parts and weapons require to function e.g. shields, plasma cannons, beam weapons etc.
In addition to the default Base Warp Engine, there are four additional engines that each civilization can acquire by performing the relevant research:
|Engine name||Research required|
|Base Warp||None (default engine)|
|Improved Warp||Warp level gradation|
|Zero Gravity||Warp wave recycling|
|Dark Energy||Efficient warp level gradation|
|Hyperspace Energy||Advanced warp wave recycling|
Each engine is available in three sizes (small, medium and large). Speeds provided and fuel consumption are the same for each of these sizes, however, the energy provided and costs differ (large engines are more expensive and provide more energy than small).
|Engine name||Size||Thruster (km/s)||Free warp||Max warp||Energy||Fuel factor||Farsu||Credits||Build (secs)|
- Thruster: speed used within a star system and during battle
- Free warp: maximum warp speed without using fuel
- Max warp: maximum warp speed using fuel
- Energy: energy generated per engine (which can be used to power shields, energy weapons etc.)
- Fuel factor: how fuel efficient the engines are (the lower the better)
- Farsu: cost in farsu
- Credits: cost in credits
- Build (secs): required build time during ship construction
Any engine is compatible with any hull. Depending on the size of the hull, there will be a small, medium or large version of an engine available in the ship designer which can be fitted to the hull.
The size of the ship hull determines how many engines it needs. A small hull could require only a single engine, whereas the larger hulls can need over ten.
When more than one engine is fitted to a hull, the maximum travel speeds do not increase. However, the resource costs, build time, energy generated and fuel consumption do increase proportionately.
There are two types of speed engines can provide: thruster and warp.
Thruster speed is the automatic speed at which a ship will travel while in a star system or during battle. It is automatically engaged under those conditions (the selected warp speed is ignored).
Outside of a star system (and when not in a battle) ships can travel at warp speed. Warp speed is significantly faster than thruster speed (warp 2 and above are faster than the speed of light).
|Warp||Light years per hour|
Free warp is the warp speed at which engines can operate without using fuel (olzine). To travel faster than the free warp speed, the engine must have available fuel.
Olzine is the fuel used by ship engines. Without fuel, ships can only travel at thruster or free warp speed.
Travelling at faster warp speeds increases fuel consumption (each additional warp level will consume more fuel than the previous level).
The fuel factor also determines how fuel efficient an engine is (the lower the fuel factor, the more fuel efficient an engine is).
Fuel is stored on a ship using fuel tanks (fuel cannot be added to a ship if no fuel tanks were included in the design). Multiple fuel tanks increase the ship's fuel capacity. Fuel tanks are available without having to be researched (available in small, medium and large sizes).
When a ship is constructed, its fuel tanks are automatically filled if there is olzine available. Fuel tanks can be filled manually at any planet by transferring olzine to the ship (up to the combined capacity limit of the fuel tanks).
