Modular Engines
Modular engines are customizable engines in Stormworks. There are different variations with size: small, medium, and large. Intakes for the modular engines are fuel, air, exhaust, and coolant to ports located on the engine manifolds. The crankshaft is the base of the engine and have six connections (4 piston connections and 2 crankshaft connections) to make the engine. The four piston connections are along the sides of the crankshaft. The two crankshaft connections are to connect adjacent crankshafts and are opposite of eachother. The crankshaft can also connect to clutch, crankshaft 1x1 to 3x3 connecters, and crankshaft 3x3 to 5x5 connetors from the crankshaft connections. The size for the crankshaft are 1x1, 3x3, and 5x5 connecting to the piston of equal size and can connect to a crankshaft belt of equal size.
Crankshaft belt
The crankshaft belt comes in 1x1, 3x3, and 5x5 suited to the crankshaft of the same size. It has one connection to the crankshaft with connections on its sides varying between size. The connections on the sides connects an alternator, starter, or impeller pump. The 1x1 connects up to 4 on its sides, 3x3 connects 8, and the 5x5 connects 14. The starter is for starting the engine and multiple can be added. The more starters added, the quicker the engine will start. For 1x1, a starter per six pistons. For 3x3, one per piston, and for 5x5, two per piston. The ratio is ideal for the number of pistons matching the number of crankshaft with zero clutch input (double the amount if fly wheel is included).
Clutch
The clutch is attached to one end of the crankshaft (two without the crankshaft belt) and is used to transfer power. The clutch is controlled by a variable logic connection. If the engine starts from a self contained starter, it should start at the value of zero to start. If the starter (ex. Electric motor, another engine, or fly wheel momentum) then it can be put to a higher variable to start.
Fly wheel
The fly wheel is apart of the engine to maintain momentum, inturn, a longer start. The fly wheel also creates slower throttle response but allows for maintaining RPS of an engine.
Pistons
The modular engine piston powers the engine. The piston, like the crankshaft, comes in 1x1, 3x3, and 5x5 connecting to the crankshaft of equal size. All piston have 5 connections (4 manifold connections and 1 piston to crankshaft connection) and connects to air, fuel, exhaust, and coolant manifolds with the crankshaft on one end. The piston connections vary by size for manifold connections. The 1x1 conects on four of its sides, all sides except opposite of the crankshaft connection. The 3x3 piston have manifold connection on two of its sides, opposite of eachother, and .25 meters (1 block) from the base side with the connection to the crankshaft. The 5x5 piston is similar to the 3x3 with manifolds on 2 sides but .5 meters (2 blocks) from the base and .25 meters (1 block) from the top.
Intake
The manifolds (air, fuel, exhaust, and coolant) connects to the pistons in order to feed the engine. The manifolds are constant size for all engine sizes. The ideal ratio is 1.0 for air and 0.5 for fuel, using the variable logic connection. The exhaust should be connected to an external port and can function under water with the right pressure. Unlike the others, the coolant manifold has two connections, the connection can input, with the other connection outputting, coolant and can work both ways.
