Here is an article on the prospects for an adiabatic turbo diesel from 1987 adiabatic diesel engine technology in future transportation.
Ceramic engine valves.
The engine was built from a new bare gm performance parts ls2 engine block to take advantage of its larger 4 00 inch bore but the rest of the external dress was standard camaro ls1.
Interest in and experimentation with ceramics in the internal combustion engine ice goes way back.
Powerkote cbx ceramic thermal barrier coating.
12 5 1 compression ratios nitrous oxide n2o supercharged or turbocharged.
Creates a hard surface specifically designed for engines running high volumes of fuel and or high compression ratios or closed chamber heads.
Herbert gasthuber roland krebser using ceramics for mass reduction in valve train 4th international symposium on ceramic materials and components for engines 10 1007 978 94 011 2882 7 1059 1066 1992.
Jacers is a leading source for top quality basic science research and modeling spanning the diverse field of ceramic and glass materials science.
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.
Current trends in spark ignition engines are toward multivalve engines capable of operating at relatively high speeds to maximize performance and fuel economy at acceptable emissions levels.
For all other applications use cbc2 above.
Intake valves usually do not suffer as severely as exhaust valves which see combustion chamber temperatures.
The japanese concern touts the environmental advantages of its ceramic auto components which include exhaust control valves diesel fuel injection components and gas turbine components.
Ceramic and ceramic head valves have been demonstrated for use as exhaust valves at only 40 percent the mass of steel valves but the brittle failure mode of ceramic versions can have devastating consequences on the engine.
This reduces the friction particularly in engines where oil flow is restricted to the head.
Thermal barrier coating designed for performance engines running.
We do this by the application of a dry film lubricant.
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.
The unique ceramic material bonds itself to most critical components in the engine.
