Ceramic Engines
Just thought I'd ask the question as there seems to be a few knowledgeable people frequenting this forum.
Why haven't ceramic engines taken off. A Google search brings up hundreds of articles from 10 years ago saying ceramic engines at one third the weight of iron or aluminium blocks are just around the corner. Hundreds of YouTube videos show running engines. Turbos have long been made from ceramics, as has turbine engine compressor blades. Ceramic coatings are seen on pistons etc.
So what's been the problem with ceramic blocks? Light weight but brittle?
