To control a modern diesel engine you need to control:

Fuel injected quantity (IQ)

Fuel injection timing (SOI)

Fuel injection duration

 

In order to control fuel injection you must know how much air is flowing into the engine and you must know the engine speed.

So you have 5 factors very closely linked.

1. Mass of Air Flowing (MAF)
2. Fuel Injected quantity
3. Fuel injection timing
4. Fuel injection duration
5. Engine speed (rpm)

The following guide
