What Happened To The Ceramic Engine

The sarich orbital engine is a type of internal combustion engine invented in 1972 by ralph sarich an engineer from perth australia which features orbital rather than reciprocating motion of its internal parts it differs from the conceptually similar wankel engine by using a generally prismatic shaped rotor that orbits the axis of the engine without rotation rather than the rotating.

What happened to the ceramic engine.

Automotive ceramics are only one of several types of advanced structural ceramic. Ceramics are used in engine applications where there isn t any impact or tension loading ceramic ball bearings turbos are a good example as well as valves cams etc. Due to the thermal insulating properties you can also find ceramic coatings in engine areas that need to withstand high heat like pistons or exhaust headers but this is typically not standard because of the increased cost of production. Interest in and experimentation with ceramics in the internal combustion engine ice goes way back.

Ceramics as compared to metals have lower density and higher specific strength. Davis a renowned astrophysicist who worked as a subcontractor and then a consultant for the pentagon ufo program since 2007 recently stated that in some cases the examination of the material retrieved from some ufos has according to the new york times failed to determine their source which has led davis to conclude that we couldn t make it ourselves the new york times went on to explain davis who now works for aerospace corp a defense. Toughened zirconia were being contemplated with the hope that the technology would have more use as fabrication capability and cost improved. Here is an article on the prospects for an adiabatic turbo diesel from 1987 adiabatic diesel engine technology in future transportation.

Therefore decrease of the parts weights will increase the engine efficiency. This is an inevitable choice because metal was the only choice at that time. Replacement of the materials of the moving parts from metals to ceramics will result in higher engine efficiency. For a survey of the issues involved in adapting ceramics for demanding structural applications see advanced structural ceramics.

Ceramic engine is a direction. At that time ceramic cylinder piston and combustion chamber coatings e g. The high strength heat resistance and reliability of the metal make it the perfect choice for engine parts. Ceramic engine parts or even an entire engine made from ceramics which are stable to 4 000 degrees f could be an answer but the material remains expensive.
