Ceramic Engines?

So, apparently they're thinking of making engines out of ceramic now because they would be able to operate at higher temperatures which would lead to better efficiency, less pollutants, and better fuel economy. The only problem is that the sensors integrated into the engine wouldn't be able to withstand such high temperatures of heat, so scientists are figuring out a way to make it so that the sensors can withstand that type of heat.
