What Are Ceramic Engines

Cre s near adiabatic ceramic rotary engine should be 1 more efficient 2 a lot smaller and yet more powerful 3 smoother running and 4 cleaner burning emitting less pollutants.

What are ceramic engines.

In 1988 toyota introduced it s ceramic engine into its toyota crown line. The high strength heat resistance and reliability of the metal make it the perfect choice for engine parts. Ceramic engines would use this energy more efficiently. Sialon is silicon aluminum oxynitride i feel nitpicky.

A ceramic engine is a type of engine made of ceramic. Since the invention of gasoline and diesel engines in germany in the late 19th century car engines were made of metal. They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments. The only ceramic engine available would be some ceramic made up of bubbles that had walls very thin so the flexibility would exceed the strength.

Here is an article on the prospects for an adiabatic turbo diesel from 1987 adiabatic diesel engine technology in future transportation. For a survey of the issues involved in adapting ceramics for demanding structural applications see advanced structural ceramics. Making a whole engine of ceramic material though would be ridiculous. Turbine engines with ceramic parts or ceramic coated metal parts are currently in operation as auxiliary power sources.

Turbine engines made with ceramics could operate more efficiently giving aircraft greater range and payload for a set amount of fuel. Currently even blades made of advanced metal alloys used in the engines hot section require cooling and careful limiting of operating temperatures. Ceramic parts for gas turbine engines may be practical. This is an inevitable choice because metal was the only choice at that time.

Ceramic engine is a direction. Some elements such as carbon or silicon may be considered ceramics ceramic materials are brittle hard strong in compression and weak in shearing and tension. A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material. In 1982 isuzu aska tested a car with an all ceramic engine near the kinko bay.

Also to the toyota gtv line. Automotive ceramics are only one of several types of advanced structural ceramic. They loose little heat operate at higher temperatures burning more fuel and pollute less.
