copy/paste:
"A couple of decades ago, Toyota researched on producing a ceramic engine which can run at a temperature of over 6000°. Ceramic engines do not require a cooling system and hence a major weight reduction in fuel-efficient vehicles. Fuel efficiency of the engine is also higher at high temperature. In conventional metallic engine, much of the energy released from the fuel must be dissipated as waste heat in order to prevent a meltdown of the metallic parts. Despite all the desirable properties, such engines are not in production because the manufacturing of ceramic parts is difficult. Imperfection in the ceramic leads to cracks. Such engines are possible in laboratory research, but manufacturing difficulties prevent them from becoming reliable products."
now this is a couple of decades ago. ceramics have and still are being used in a lot of various industry. i cannot imagine that they can't build a engine which would be mass producable by this time.
