Abstract
The present trend of internal combustion engines toward higher-speed and higher-output capacity is pressing the need for improved lubrication of sliding parts in the combustion chamber to secure reliability.
To meet this need, investigation into frictional phenomena was made with a rotary engine, which led to the development of a method of coating the inner surface of the rotor housing with fluorocarbon resin superior in self-lubrication and friction resistance.
Rotary engines given this surface finishing showed no trace of irregular wear of the sliding surfaces even when subjected, prior to completion of run-in firing (in green condition), to high-speed and high-load tests, indicating this method's noteworthy benefit of improving comformability.
This method offers an excellent surface finish for sliding parts of internal combustion engines (rotary and reciprocating) which will gain increasingly higher output in the future.
