Engine opened, what is this pattern

Hi,
a mis-selected glow-plug detached its glowing part from the body and drop off to cylinder space. And hitted valves and cylinder head, made some scratches and holes. We fixed the head and valves, but I tooked a picture I want to ask a pattern on the cylinder, this is the injectors pattern. But does it ment to inject most of the fuel inside the gap. I think my injectors does not. But I don't know exactly how this jtdm engine works. Can someone explain to me?

After all that, we cleaned all injectors, I toughted car will get higher mpg, but computer show a little lower mpg than before. I saw injectors, they were in very bad shape, now car has lower noise, lower vibration, silky smooth acceleration. I know that before cleaning computer showed me +10mpg than actual. like I calculate my mpg after I fill the tank, like 57mpg but computer tell me 67.2mpg. now after cleaning, it shows 59mpg straight. I will calculate after I fill the tank but, can this happen?

that pattern can be caused by either the pilot injection or by the regeneration process of the DPF.

I don't believe there's any relationship between the JTS and JTD engine so parts won't be interchangeable.
