I have seen descriptions of fully ceramic engines that does not need oil or watercooling. But that is expensive and difficult to machine.
So can you apply a coating (TiN or some other PVD coatings? Or maybe hard chrome coating?) on the cylinder walls and the piston rings made from traditional metall to make it so it does not need oil lubrication? For the crankshaft /connecting rod bearing you can make that a ball bearing or roller bearing either from ceramics that does not need lubrication, or you can make it sealed permanently lubed bearings that does not need external lubrication.
I know some firearms parts and roller chains and so on use DLC coating so it does not need lubrication. But from what i read it has a service temperature of only 250 degree C so that will maybe not stand up to the combustion temperatures?
