As I said before - several times. "Timing" is a vague reference that can mean many things. I certainly wasn't referring to just ignition timing, and Guido never clarified his very vague question. In fact - he never said anything about this being a four-stroke-cycle engine, a two-stroke-cycle engine, or something else.
If you are asking me how many TDCs occur in an Otto Cycle engine for every power stroke - that's a pretty easy one. You are throwing in a bunch of specific details that have noting to do with Guido's vague timing declaration.

This vague reference to "timing" sounds like basic text-book teaching without the discussion of reality in the engine world.
