General


Fusion Engines are the powerhouse of a BattleMech and are mounted in the Center Torso.

Engines provide the power necessary to move a 'Mech and fire its weapons. Unlike internal combustion engines, Fusion Engines generate power by fusing hydrogen isotopes (1H) much like the center of a sun. Despite conventional thought, these Engines are not potential mini-nuclear explosions. When damaged to a significant degree they will automatically shut down all fusion reactions and power down the BattleMech. WARNING: To override this shutdown process the default button on all Engines is 'O'.

Engines not only produce power but also have a power loss, which leads to the advent of heat, that needed to be dissipated, thus needing at least 10 Heat Sinks to work.

  • Engines with a power rating of less than 250 require extra Heat Sinks.
  • Engines with a power rating of 275 and higher provide extra slots, that take only Heat Sink (without consuming additional Critical Slots on the 'Mech).

Variants


Each 'Mech comes with its own Standard-Engine from stock. This Stock-Engine defines the maximum power rating of the 'Mechs Engine upgrades, thus limiting its maximum speed (Restrictions Formula).

Engines come in two different variants and a Stock-Engine may be of either type, depending on the 'Mech model.

Standard-Engine

Equipment Overview
Standard Engine 
Engine
Tech Base: Inner Sphere 
Equipment Type: Equipment 
Critical Slots: 6  


[1][2]


  • Requires 6 Critical Spaces only
  • Build for the battlefields, small, sturdy and low-cost, but heavy. A Standard Engine cost less than a comparable XL-Engine, but weigh about double.
  • 'Mechs mounted with a Standard-Engine are less vulnerable:
They have no parts of the Engine in their Side Torso and can survive its destruction.
Making only the Center Torso a Critical hit-zone.
  • low (standard) repair costs.








XL-Engine

Equipment Overview
XL Engine 
Xl engine
Tech Base: Inner Sphere 
Equipment Type: Equipment 
Critical Slots: 6 +3 +3  


[3][4]


  • Expensive - Acquirement costs about 4x times of a equally rated Standard-Engine.
  • Lighter - Due to the usage of lighter materials an XL-Engine weigh about 55-64% less than a Standard-Engine of same power rating.
  • Bulkier - Further 3 Critical Spaces in each side of the torso are required, adding to the 6 of the Center Torso.
    • 'Mech is more vulnerable, for their Engine extrudes its bulk into the sides (RT+LT), making the whole Torso a Critcal Hit-zone you may want to keep healthy.

Historical Footnote about the Engine Table

The Engine weight table does not match TableTop rules, as it includes the Cockpit (3 tons), Gyro (Power Rating/100, roundup) and an adjustment for required Heat Sinks up to the minimum of 10 in Mech Lab for engines rated at less than 250. (See FAQ for more information)

Coming to Speed


'Mechs are restricted on how fast they can go by two factors:

  • Stock-Engine power rating
  • Tonnage

Restrictions Formula

  1. Maximum-Engine power rating cannot exceed 400 or ~8.5x the 'Mech's tonnage, whichever is lower.
  2. Maximum-Engine power rating with (round up to nearest 5 or 0):
  • Light 'Mech = 1.4 x Stock-Engine
  • Medium 'Mech = 1.3 x Stock-Engine
  • Heavy 'Mech = 1.2 x Stock-Engine
  • Assault 'Mech = 1.2 x Stock-Engine

Example: Limitation by Stock-Engine rating

A Hunchback HBK-4G is a 50 ton medium 'Mech and comes with a 200 rated Stock-Engine. The first restriction placed on it is, that it cannot use an Engine rated higher than 8.5 multiplied by its tonnage (8.5 x 50 = 425). Since no 'Mech can use an Engine rated higher than 400, the first restriction caps it at a 400 rated Engine.

The second restriction says: the Hunchback cannot use a Engine rated higher than 1.3 times its Stock-Engine rating of 200 (1.3 x 200 = 260). This means it cannot use an Engine with a rating higher than 260.

Since the max. Engine is limited by the lower of the two rules, the highest Engine the Hunchback can use is a 260 rated Engine.

Example: Limitation by tonnage

The Cicada CDA-2A is a 40 ton medium 'Mech and comes with a 320 rated Stock-Engine. The first restriction placed on it is, that it cannot use an Engine rated higher than 8.5 multiplied by its tonnage (8.5 x 40 = 340).

The second restriction says: the Cicada cannot use an Engine with a rating higher than 1.3 times its Stock-Engine rating of 325 (1.3 x 325 = 422.5 rounded up to 425). Since no 'Mech can use an Engine rating higher than 400, the second restriction limits it to a max. Engine rating of 400.

Since the max. Engine is limited by the lower of the two rules, the highest rated Engine the Cicada can use is a 340 rated Engine.
