Always active "engines" and separate throttle parts

[bananasrawesome]

I need to make an engine which has fuel input controlled by an external throttle part. Any ideas on how this can be done?

Try taking a look at Throttle Controlled Avionics' code. It controls engine throttles by adjusting their thrust limiters.

You are going to need a module that listens for the throttle and creates thrust according to that, and a module that gives the maximum thrust of the engine.

AKA "an engine".

So I create a global variable which is used by the throttle and propulsion modules but how do I make the module produce the thrust? Is there something in the KSP api I could use?
