HELP IM THE ONLY ENGINEER

Colors:need nine of these

A gas filter set to configuration mode.

So you're new and no one else has joined engineering and you have no idea how to setup the engine? Well first things first: don't panic! You could try waiting for an engineer to join and teach you... unless you've joined during deadpop hours, in which case, the following steps will get the engine rolling quickly with minimal explanation. You should probably read the rest of this guide to understand how it works in greater detail once you're done:

• If everything is out of power, skip to here.

1. Open a radiation PPE locker (one is found near the entrance to the engine room) and put on safety goggles, a radiation suit, and radiation hood.
2. Retrieve three Phoron canisters from hard storage (the room with two doors across from the equipment room with all the lockers) and move them to the engine room.
3. Wrench one of the canisters into the north connector (highlighted in COLOR).
4. Wrench another canister into the south connector. Do not turn the pumps on yet.
   • You do not have to open the canister valve on the canister UI. Don't worry about that.
5. Move to the northern end of the engine room and click on the filters (highlighted in COLOR). Click "configure", then click the button that says "Nitrogen" and change it to Phoron. Do this for both filters, and turn them both back on.
6. While you're up here, click the engine SMES (highlighted in COLOR) and maximize both its input and output values.
7. Move back south and click the pumps (highlighted in COLOR), maximize the pressure, and turn them on.
8. Move a little bit more south and click the pump (highlighted in COLOR), maximize the pressure, and turn it on.
9. You should see the canisters beginning to empty. Once the indicator light starts flashing, unwrench the canister on the south connector and plug in another one. If you did everything correctly up until now you should see purple stuff floating around in the core.
   • If you cannot see inside the core, click the reactor blast doors button on the wall (highlighted in COLOR).
   • If you do not see purple stuff floating around inside, check the pump (step seven, COLOR) on the northern connector. Otherwise check your filters (step five, COLOR) to make sure they are filtering Phoron, and not some other gas.
10. Move over to the emitter (highlighted in COLOR) and click on it. Count the amount of times it fires.
11. After twenty shots, turn the emitter back off by clicking on it.
12. Close the SM core blast doors so that radiation doesn't spread to the rest of the engineering hallway.
13. Head north and open the blast doors to the waste processing room (highlighted in COLOR). Turn on and maximize all pumps, and turn on all three of the gas coolers (their values don't need to be modified).
14. Head to the main distribution SMES (highlighted in COLOR) and maximize its input value. You can maximize its output value as well, but it shouldn't be necessary unless the station is very well populated and you're somehow the only engineer.

Congratulations, you have successfully setup the engine, and everyone can enjoy their round in a powered station. You're a hero for as long as no one finds out you used Phoron, an incredibly scarce resource! Unless you set something up wrong and now everything is either still out of power or in the process of exploding. For the former's case, refer to the quick diagnostic list. In the latter's case, head to this section.

The Actual Guide

Now, assuming you aren't new and actually know a bit of what you're doing, then this guide will attempt to accurately describe the intricacies and in-depth mechanics of most of the systems related to the SM engine, from the SM itself to the SMES units connected to it at the end of the line. An informed mind is one that can potentially save the station from disaster!

How It Works

On the surface level, the default engine setup is very simple: SM is energized, SM heats up gas, gas goes to TEGs, TEGs exchange heat and produce power, power goes to the SMES, etc. The sections below will cover what makes each individual part tick.

The Supermatter

See also: Phoron
The Supermatter (often known as the SM) is a large crystal of tightly compacted Phoron with special properties. This particular crystal differs from typically large quantities of Phoron in that it is a semi-transparent yellow instead of an opaque purple, and it even glows. Another contrast is that the Supermatter is incredibly unstable, and is capable of vaporizing solid and liquid - and sometimes gaseous - matter in an instant (this includes you). It can even consume photonic energy in the form of lasers. This process usually results in the Supermatter becoming "energized", a state at which it will begin to slowly shed Phoron and oxygen particles (roughly at a ratio of ten moles of Phoron to one mole of oxygen, depending on the temperature of the environment), as well as radiate Gamma rays and produce incredible amounts of heat. It is also in this energized state that its visual appearance will distort in the minds of the beholder, assuming they are biologic (excepting Dionae), and will inexplicably stimulate the visual cortex of the brain to hallucinatory extremes. A footnote in its energized state is when high concentrations of oxygen are introduced, forcing the crystal to radiate a red glow instead of its usual yellow. Intermittently, the crystal will also cease glowing all together. This interaction between the SM and oxygen is poorly understood, but what is known is that the crystal will passively energize in its presence at a rate dependent on how much oxygen there is. Put simply, anything shot/thrown at the SM will energize it, producing heat and lethal amounts of radiation, and probably hallucinations.

The Supermatter in its default state does nothing unless you do something to energize it. It does not produce Phoron or oxygen, it does not radiate Gamma rays, it does not generate heat, and it does not cause hallucinations. Though viewing it without protection in an unenergized state is poor form, it is safe nonetheless. It is also safe to pull the SM around freely. It is not safe to walk into/against the SM, nor is it safe to click on it; this will disintegrate you immediately. Removing the SM from a crate in an environment with oxygen (such as a hallway or poorly maintained SM chamber) also isn't safe for the reasons outlined above.

While being basically space magic is all well and good for the purposes of generating power, it's also incredibly dangerous if not managed properly. Besides being able to heat up its surrounding atmosphere to rather high temperature extremes when energized, it is also capable of exploding spectacularly, known as a "delamination event". Most commonly this occurs when the crystal's structure begins to decay as a result of extremely high heat, particularly at five thousand Kelvin and above, and the SM will eventually detonate if this is not corrected. It can also decay if it is exposed to vacuum while energized. Though the Supermatter can be "damaged" in a way, it is also capable of regenerating itself if allowed an environment in which it can do so. It is prudent, then, to keep the SM from becoming over-energized and heating its environment up to a point where it can self destruct, a task that isn't that difficult since all Supermatter crystals provided by NT come with a device that will broadcast over the radio its status if it is concerning.

TL;DR: Energizing the SM (shooting it with the emitter/a gun, or touching it with something else/yourself, or introducing oxygen to it) will make it produce heat and radiation, and start spewing Phoron and oxygen, and make you hallucinate without safety goggles. It begins to take damage at 5000 Kelvin, and this damage scales with temperature. It can also take damage if exposed to vacuum (even 0.1 kPa of gas will save it) while energized. It will explode and irradiate the entire map if allowed to take damage for too long and everyone will get pissed at you, mostly because the SM itself will yell at you over the radio if it's taking damage.

The TEGs

Your typical TEG UI in an unpowered state.

Something much better understood compared to the SM are thermoelectric generators, or TEGs as they're often shortened to. The basic operating principle of any TEG is that it uses the difference in temperature between gas to generate electricity, the result being power based on the difference and slightly colder/hotter gas. In practice, the Supermatter - when energized - will heat up its surrounding atmosphere to a rather high degree. These gases are then pumped into one of the turbines (the north one) on the TEG, where it will exchange heat with the turbine on the opposite end (the south one) that hopefully has gas that is significantly colder. This turbine has gas being pumped in from a somewhat extensive radiator network in space, where it is slowly chilled. The two gases exchange heat with each other, producing energy, and the difference in temperature between the two is lowered slightly. Note that TEGs can safely produce up to five hundred kilowatts individually, beyond which they will begin to grow a little less consistent in their power generating capabilities. There is no danger in going above this threshold, however.

A TEG also needs some sense of flow in order to function, meaning a turbine's input and output sharing the same pipe network without something to break it up will function rather poorly, if it functions at all. In particular, the turbine's input requires gas to be moved towards it specifically. Most commonly, a pump of some sort can be found connecting much of the cold loop to a small section of pipe connected to the turbine's input. While it may not be obvious, the hot loop does actually possess a pump in the form of a vent constantly scrubbing gas from the air. A TEG turbine has specific sides that its input or output can be found on, which can be found by simply examining the turbine.

In all honesty, most of the values shown in the UI aren't necessary at all to know except for output. If the TEG's sprite looks green then all is well on the TEG's end. Regardless, the values will be described anyway:

• Total Output: The amount of power available that can be output into a wire. You even get a cool looking bar that shows how much power is being generated! Wow!
• Thermal Output: The actual amount of power being generated. Due to inefficiencies with the system, some power is lost, hence the existence of the Total Output value.
• Turbine Output: How much power the turbines themselves are generating, independent of thermal exchange. Probably.
• Flow Capacity: Literal mystery number.
• Inlet/Outlet Pressure/Temperature The pressure and temperature of the inlet and outlet, measured in kilopascals and Kelvin respectively. As you can imagine, the inlet refers to the pipe network connected to the input of the TEG, while the outlet refers to the pipe network on the output side.

For more information on how gas interacts with the TEGs, refer to the coolant section of this guide.

Gas and Heat

Something something fire triangle

Safety First

Before entering the engine room you should always wear the following:

• Safety Goggles to prevent hallucinations from developing by looking at the SM. How do they work? Who knows...
• Radiation PPE to keep you from receiving a lethal dose of radiation that can very easily kill you within minutes. Dionae and IPCs are exempt from wearing this.

As long as you have these two sets of items you are pretty much safe unless the engine room is either an inferno or vacuum. Certain hardsuits and voidsuits are immune to radiation as well if you need to wear those out of necessity.

Файл:SMES.pngSMES Configuration

There are two SMES units that are immediately relevant to the engine: the engine SMES and the main distribution SMES. The former is what receives power from the TEGs and powers the engine room APC directly as well as the emitter. If the output is not high enough, the emitter may not fire, or the APC may not have enough power to allow the pumps to operate. The other SMES also receives power from the TEGs, but it outputs to the rest of the station. It should have its input maximized, since every kilowatt not used is another kilowatt wasted. The output can be adjusted as needed, of course, but one should take into account how populated the departments are and how much power the station will need in general.

Coolant

An intrinsic property of matter - particularly gas, in SS13's case - is something called heat capacity, a variable that determines how much energy it takes to increase the temperature of a substance. In the context of setting up the SM: how energized the SM needs to be in order for the gases in the hot/cold loops to actually rise in temperature. Heat capacity also factors into how power is generated with the TEGs; higher heat capacity allows a gas to hold more thermal energy, which means more energy can be transferred between the turbines, allowing more energy to be produced.

• Phoron: Arguably the most stable and safe gas to use, Phoron carries with it a stupidly high heat capacity, at least compared to most other available gases. There is a lot of leeway with this particular gas, making it easy to train new apprentices with. It's worth noting, though, that phoron is a fuel, and can start fires. The SM will generate Phoron passively as long as it is energized. This gas is viable for either the hot loop or the cold loop.
• Hydrogen: Second best gas to use with the second highest heat capacity, and it compares pretty well to Phoron, at least compared to the other gases. Like Phoron (sans all the wacky space magic that comes with it), Hydrogen is a fuel, and can start fires. It is otherwise inert and safe to breathe as long as you don't light a match. This gas is viable for either the hot loop or the cold loop.
• Nitrous Oxide: Not nearly as good as Phoron or H2 (in fact it's leagues below these two), it's still a respectable gas nonetheless. Its only caveat is that it is an oxidizer, and it will start a continuous fire if used in the hot loop, though the heat generated from such isn't as bad as one might think. It can also knock people out if exposed to the atmosphere, but almost all of these gases are dangerous in high quantities anyway. This gas is viable for the cold loop, but less so for the hot loop unless it is monitored.
• Carbon Dioxide: Just under N2O in terms of heat capacity is CO2. This gas pretty much has nothing going for it other than that, but it is totally viable for use in the hot or cold loop. You'll probably see this in the chamber anyway as a result of the SM producing Phoron and oxygen passively (which almost immediately burns up into CO2). This gas is viable for either the hot loop or the cold loop.
• Nitrogen: Lowest heat capacity, twined with oxygen, N2 has been regarded as the standard coolant for the SM engine, but the fact of the matter is that this is definitely no longer the case, and N2 should really only be reserved for experimentation or as emergency dump coolant. This gas is barely viable for anything.
• Oxygen: Same heat capacity as N2, except it's also an oxidizer (obviously). Oxygen can also energize the SM. Because of this, using this in the hot loop will almost definitely result in a roaring, nearly uncontrollable blaze eventually. That's not to say that it can't be controlled, but this shouldn't be the first gas you look at for coolant. The SM will generate oxygen passively as long as it is energized. This gas is barely viable for anything.
• Air: Literally just 79% N2, 21% O2. Why would you use this. I mean, you have a lot of it, sure, but... why? For the reasons listed on the O2 section, using this is a terrible idea.

Waste Processing

While this whole shebang doesn't impact SM performance too much, it's a good idea to set it up anyway. The north end of the engine room beyond the configurable filters is a black pipe network with two pumps, a connector, and three gas coolers. This is the waste line, and any byproducts/gases that you didn't program get filtered out from the hot loop and end up here. As it turns out, siphoning gas from a blazing hot almost-inferno of an engine chamber gives you very hot gas, which has expanded considerably, making most atmospheric devices function slowly, particularly the devices in Atmospherics, assuming the waste gases are allowed there via the pump connected to the scrubber line. Thus it's a good idea to cool the gas down with the gas coolers. The simple way to set this up is to turn on and max both pumps and turn on all three gas coolers. Alternatively you can plug in an empty canister into the connector instead of pumping the gases into the scrubber line, but there's no real reason to unless you just want to expand the volume of the waste network.

Emergency!

First you should make sure you have power lmao

Coolant Dump

Should make sure the pipe pressure isn't over 15000 kpa or you're kinda screwed

Upgrades

SMES upgrade, more TEGs, better use of coolant, more pumps, blah blah blah
