Aluminum blocks always have sleeves whether gas or diesel. I think the block in that picture is a Dart BBC.
Not always.
Chevy early aluminum V8s had a coated aluminum bore.
I don't recall what the coating was called right now (something lame sounding, I remember that much) and it didn't last worth a shit.....but they used it that way for like 20 years.
Just googled...
Nikasil
It's ceramic spray in shit.

Its nickel plating. Works good on two cycle engines.

BMW tried Nikasil for a while. They changed to Alusil afterwards. Alusil is another form of unlined aluminum block, but it seems to actually work.

What the fuck??? REALLY???

How long does it last?
How long does it take to charge?
And how many pounds per strike? Because from the sound of it alone it CANNOT be more than 15 pounds...


It doesn’t sound tougher than my SDS max corded Hilti rotohammer. And it looks way heavier.

uh uh

Nickle - Silicon
Nikasil is short for nickel silicon carbide. Silicon carbide is a very hard ceramic (much harder than steel) that can be dissolved in nickel. The nickel silicon carbide solution can then be electroplated onto the aluminium cylinder bore. After the cylinders are plated, the Nikasil bores are diamond honed to a plateau finish. Pistons will need to be fitted with Nikasil compatible piston rings as chrome rings commonly used with cast iron bores are not compatible.
