Engine Specs
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
|
- 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
|
- 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.
Coming to Speed
'Mechs are restricted on how fast they can go by two factors:
- Stock-Engine power rating
- Tonnage
Restrictions Formula
- Maximum-Engine power rating cannot exceed 400 or ~8.5x the 'Mech's tonnage, whichever is lower.
- Maximum-Engine power rating with (round up to nearest 5 or 0):
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.
