From what I have heard on this, the computer adjusts the timing, spark, fuel injectors, and temporarily shuts them down when there is not a demand for full power from the engine.It's kind of like the other four cylinders are just moving up and down in the block but are not producing power until they are activated. That is the best way that I could imagine this is accomplished. I hope it helps give you a start to the answer.
