Hi All,
This is the results of a recent internal borescope examination of the engine in the SVDP BMW 120D race car. I am putting them up here more as a photo dump as well much as anything else.
The image quality overall seems poor, however, on the camera while you are looking around inside the cylinder the image quality seems much better. The video helps but still not as good as you see.
This is the video.
You are traveling down through the injector hole (glow plug hole is to small). You will see the liner passing top left to bottom right.
Cylinder 1
Injector
Glow plug
Liner, note the long scratches, these are normal wear. The black spots are inclusions.
The back side of the air inlet, quite black and sooty.
Cylinder 2
Injector
Liner, heavier striations.
Cylinder 3
Injector
Glow Plug
Liner, lots of striations and inclusions.
Back side of inlet valve.
Glow plug
Liner, heavy radial mark, lots of marks.
More marks and inclusions.
Cheer,
Richard B.
