That is not a distributor but a coil pack.

It actually contains 2 seperate coils each of which sparks 2 plugs.

So aproaching TDC on cylinders 1 & 4 the first coil is triggered and sparks appear in both cylinders one of which is near the end of its exhaust stroke and so the spark does nothing, the other cylinder is near the end of its compression stroke and starts the power stroke. The next time these 2 cylinders are in this position it again fires. This is redundant spark.

The other coil does the same for cylinders 2&3.

The ECU uses a pickup on the front of the engine to tell it when and how fast the engine is running to trigger the sparks at the right time.

 

Hope that this helps.
