I want to know if it is the same cut of injection and cutting injection ... !!! And if you can give me some data where to get information and name its parts if possible .. !! Thank you please if you can answer as soon as possible.

It depends on the interpretation for example cutting injection is the point where the injection pump begins to cut the supply for the control of the maximum engine revolutions of the
engine cutting can be the engine off (the pump supply is cut) it can also be the start of supply (start of the injection) or also the cut of revolutions as in the first case as I said it depends on the context
