Modular engine

Components COLLAPSE!

Crankshaft

Crankshafts are the core of an engine. Cylinders can be attached to the outer surfaces, while other crankshafts can be attached in the front/back to form longer engines.

Converters allow the usage of different crankshaft, cylinder, or flywheel sizes in one engine.

Crankshafts

There are 4 unique crankshaft components and two converters.

Flywheel

A flywheel is an optional component that adds rotational inertia (or momentum) to the engine. This can help with stability and smoothness in some cases, and also help prevent stalling.

It is not recommended to add a flywheel if it isn't needed.

Cylinder

Cylinders allow for fuel and oxygen to combust. Large cylinders function in the same way as small ones, the only difference being dramatically increased fuel consumption and power output.

Cylinder	Effective Power
1x1x1	1
3x3x3	27
5x5x5	125

Clutch

A modular engine clutch allows for mechanical power (RPS) to exit the engine. An input of 0.0 indicates a fully disengaged clutch, outputting no power. An input of 1.0 will fully engage the clutch.

Differently than regular clutches, the power output starts immediately, rather than requiring an input of >0.3

NOTE: Engaging the clutch too early can prevent the engine from starting by continuously stalling it.

Manifolds

There are four manifold types:

A Fuel manifold allows fuel to enter the engine. A fuel pump is never required.

An Air manifold allows air to enter the engine. Adding a pump here is optional, but can increase power by up to 80%. It does, however, also increase heat generation and complicate the Air:Fuel ratio calculation.

An Exhaust manifold allows exhaust gas to leave the engine.

A Coolant manifold has two connections that allow coolant to enter and leave the engine. All coolant is shared throughout the entire engine, which means that a single coolant manifold can draw coolant from both outputs at the same time, provided the coolant enters the engine through another manifold. Coolant manifolds do not have a builtin pump, which means they will not circulate coolant without an external pump.

Belt addons

Belt drives are not required to build a functioning engine, and can be replaced by a second clutch. There are a number of components that can be attached to a belt drive:

A starter motor is a small electric motor used to start the engine. It can reach up to 5 RPS.

An alternator is a small generator. It is extremely inefficient compared to Generators.

A belt pump is a small pump with an inconveniently placed fluid input. It isn't very powerful or efficient, but is commonly used to circulate coolant in extremely small engines.
