An engine is a ship's main propulsion system, while thrusters are needed for fine movement and maneuvers. The greater mass a ship has, the more engines are needed to provide movement.

Grid size 7 x 4
Power consumption 40 MW Max Throttle

Inputs Power
Outputs Propulsion

Engines are 7 x 4, cannot be rotated, and must be placed with the 3rd block inside the Hull. They require 6 unobstructed squares to the left of them.

Engines will load fuel while they are unpowered. Fuel capacity is 4, and they then continue to drain fuel at a rate of 1 per 5 seconds.

At rest, while powered, an engine uses 4 power per second.
