Engine Setup (Prefab)

This guide will show you the basics of setting up a Prefab/Preset Engine. These engines come in 3 variants: Small, Medium, and Large. Further details on each individual prefab engine can be found here.

For the purposes of this guide we will be utilising the Small Engine, however the exact same steps can be used on all variants, with any information worth noting mentioned at relevant steps.

Some Groundwork

Prefab engines in Stormworks require four things: Fuel, Air, Coolant, and Exhaust. Electricity is also commonly used to start engines (see note for additional information).

Within this guide we will be utilising 2 fluid ports; the Fluid Exhaust, and Fluid Port End, these are however not the only things you can use. Please see here for more details on various fluid ports.

As mentioned prior; this guide will be utilising the Small Prefab engine, but the same principles can be applied to the other variants, exceptions will be noted at each individual step.

Step 1: Assembling our Components

There are a few components needed for this guide:

Small Engine	Fluid Exhaust
Fluid Port End	Various Pipes
Fluid Relief Valve	Fluid Tank (Small, Medium or Large)
Fluid Heat Radiator	Clutch
Small Propellor	Throttle Lever
Dial(a)	Push Button
Battery (Small, Medium or Large)

(a) - The dial is not absolutely necessary, but will be useful for trouble shooting any potential problems and will aid in demonstrating what is going on.

Step 2: Supplying Air

Step 2 Details COLLAPSE!

For this step we use the Fluid Port End on the Air intake for the engine. You will know which port is which by hovering your mouse over each port, this will show you what each fluid port on the engine corresponds to.

Air intake is denoted with the colour Green.

Step 3: Supplying Fuel

Step 3 Details COLLAPSE!

When supplying fuel to an engine we need a source of fuel. In this example, we will use a Small Fluid Tank, though this can come from any kind of fluid tank you need.

To ensure that our engine does not clog up with air, we are using a Liquid Relief Valve, this is the pipe block with a grey band around it. This block acts as a filter to prevent gasses from heading into the engine, and as it is drawing from our Fluid tank set to Diesel it will only be pulling diesel into our engine.

Both Prefab and Modular engines in Stormworks require Diesel to operate. The fluid tank blocks will default to Diesel when placed, but if in doubt you can use the select tool to configure the name, the fluid type, and the fluid level of the tank.

Fuel is denoted by the colour Orange.

Additional Note COLLAPSE!

The above setup is more than adequate for the purposes of our demonstration, as we will not require more than 5 litres/second of fuel. However, should you need to pull more than 5 litres/second of fuel you will need to use a Liquid Gas Separator. This is a small contraption used to ensure that only liquid is pumped into your desired location without moving the air from your tank.

In this image, we will be using Fluid Ports, a Fluid Pump, a Liquid Relief Valve(Grey banded pipe), and a Gas Relief Valve(White banded pipe). Orange here represents the mix of Gas and liquid in a system, blue represents Liquid output, and Green represents the gas direction within a system.

With this gadget, we filter out fluids and send them to our desired output (An engine in this exampled). And in doing so, we also filter the gasses back into our tank.

This will allow for a flow rate higher than 5 Litres per Second.
