Fusion Engines are the most common type of BattleMech and aerospace power plant in the BattleTech Universe. Fusion engines can supply great quantities of power, enough to power massive vehicles and all of their weapon systems, including directed energy weapons common on the modern battlefield. Yet when no thrust is generated, fusion engines are so efficient, they practically never need refuelling. If properly ventilated, controlled fusion reactions generate little heat. There are several sub-types of fusion engines available as well, each trading bulk for mass of the components.

Engines

Fusion Engines are the most common type of BattleMech and aerospace power plant in the BattleTech Universe. Fusion engines can supply great quantities of power, enough to power massive vehicles and all of their weapon systems, including directed energy weapons common on the modern battlefield. Yet when no thrust is generated, fusion engines are so efficient, they practically never need refuelling. If properly ventilated, controlled fusion reactions generate little heat. There are several sub-types of fusion engines available as well, each trading bulk for mass of the components.

In classic Battletech there are few types of power plants. In MW:LL we use following four:

Standard Engine

Fusion Engine

This is the most common fusion engine found all over the Inner Sphere. It is considered the standard of military grade equipment from the space faring ships down to the light scouting vehicles and tools. Military Fusion (Standard) Engines are mounted in the Center Torso.

Due to the location, Mech center torso does not receive extra damage from blown side torsos. Also STD engine have reduced damage transfer rate from destroyed back torso from 3× to 1.5×. This makes mechs equipped with standard engines considerably more resilient to grievous damage.

Some tanks, like the Partisan F or the Mars, have fusion engines.

Mechs with a standard engine lose 15% of their top speed when when their back torso has lost 80% of its armor. Once their back torso has lost all of its armor, an additional 10% of their top speed is lost (for a total of -25%).

Mechs using standard engines:

Faction Chassis Variant
Inner
Sphere
Warhammer Prime
Atlas All
Fafnir A,D,F,G
Clan Locust IIC All
Hellhound Prime,A,C,E,F,G
All stats are current as of release 0.14.10



Extra Light Engine

Damage Transfer

A technological leap lost to the fog of war. The XL engines are lighter, more expensive and prone to more easy undergo critical destruction than the STD counterparts. Other than that, they share the same power rating as the other engine types.

  • Clan require 10 slots (6 in center torso; 2 per side torso) - 1.6x damage multiplier is applied due to blown side torsos and when overheating.
  • IS require 12 slots (6 in center torso; 3 per side torso) - 2.0x damage multiplier is applied due to blown side torsos and when overheating.
  • Damage Transfers from the Arms to Side Torso, Side Torso to the Center Torso and Legs to Side Torso (see Damage Types)

Most Mechs in MW:LL use XL engines, only exceptions being the STD engine variants (see table above)

Mechs with an XL engine lose 34% of their top speed when when their back torso has lost 80% of its armor. Once their back torso has lost all of its armor, an additional 26% of their top speed is lost (for a total of -50%).



Compact Fusion Engine

Compact engines emerged in 3068. Once again developed by Lyran engineers, this engine type was apparently an alternative approach to the “smaller, harder-to-kill engine” problem initially authorized by General Nondi Steiner during the FedCom Civil War. The compact engine has 1/2 the physical size of the standard fusion plant, but weighs 50% more through the use of denser shielding and a smaller, high-density fusion bottle. One benefit of this arrangement is that penetrating hits are less likely to hit the smaller profile of the compact fusion engine than they would a bulkier standard fusion engine. A relatively new concept, few base variant 'Mechs utilize this engine. Among BattleMechs that use the compact fusion engine are the Word of Blake's Archangel and the Draconis Combine's Wight. In the face of the Blakist Jihad, General of the Armies Adam Steiner shared this technology with ComStar and—through them—other nominal Lyran allies, including the FedSuns and the Combine. Since then, sadly, Word of Blake Robes have managed to capture and reverse-engineer the technology as well.

Side torso modifier x0.66, back torso modifier x1.0, less speed loss from engine damage.

Internal Combustion Engine

Internal Combustion Engine aka ICE

On the periphery and in the dire times elsewhere, the ICE engines find their use in not only utility vehicles and mechs, but also in some main battle tanks and even some rare battle mechs. Its power output is less than a fusion engine of similar mass, meaning an I.C.E. needs to be heavier in order to have the same engine rating of a fusion engine. Internal Combustion Engines cannot power energy weapons without power amplifiers, unlike fusion engines. Many I.C.E.s can use practically any combustible material as viable fuel. ICE Engines are used due to the extremely low cost and abundance of fuel everywhere.





Fusion Engine Explosions: an urban legend that won’t die

And you protest, “But I saw a ’Mech explode on the news in a blinding flash of light! It had to be a nuke!” Or is it, “Well, what about that MechWarrior that buried a bunch of Clanners in a canyon with his exploding reactor?” Or would you ask, “Well, what about Tharkad City?” Okay…

Fusion reactors do occasionally die in spectacular manners. But most of the time, the fireworks are not actually from an exploding reactor. What typically happens is that some heavy weapon manages to puncture the reactor itself. Since the reactor interior is a vacuum, air would get sucked in and mix with the plasma, stopping the fusion reaction. Kilograms of cold air mixing with a tiny mass of plasma… And, no, there’s not enough hydrogen in the reactor to really explode with the oxygen.


That puff of hot green gas you see occasionally coming from the back of a fusion engine.

The fusion reactions in a BattleMech’s fusion engine occur only under very narrow conditions of temperature and pressure. Generally, the hotter and higher the pressure, the faster the reactions, and below a certain minimum, fusion simply ceases. If you remember your ideal gas laws from chemistry…eh…the condensed version is that when you heat up a gas, it wants to expand. If it can’t expand, its pressure increases. When a gas expands, its temperature drops. Remember those rules of thumb. Fusion reactions drop when they get cooler. There are ways for the plasma to cool other than expansion. One way is when the plasma touches the relatively frigid walls of the reaction chamber. If they do, the plasma will chill so rapidly that fusion ceases instantly. That only leaves you with a puff of hot gas, with no continuing source to damage the reactor walls.
