Enjinini eyinhloko yasolwandle, indandatho ye-piston kanye ne-cylinder liner kuyipheya ebalulekile yokungqubuzana, futhi ukusebenza kahle nokusebenza phakathi kwazo kubaluleke kakhulu enjinini enkulu. Emasongweni episton enziwe nge-aluminium yendabuko, ayikho inkinga ngenkathi yokusebenzisa uwoyela wesulphur ephezulu. Phela, okuqukethwe kwesulfure emafutheni anesulfure ephezulu kusiza ukugcoba phakathi kweringi ye-piston kanye ne-cylinder liner. Ngemuva kokusetshenziswa kwamafutha e-sulfur ephansi, ifilimu yamafutha ku-cylinder liner ayilungile njengangaphambili, nakuba ukusetshenziswa kwamafutha okugcoba inombolo ye-cylinder ephezulu akukwazi ukuqeda ngokuphelele lo mphumela. Lokhu kuzoholela ekugugeni ngokushesha kweringi ye-piston egqinswe nge-aluminium, okuzothinta ipheya yokushayisana, kukhuphule ukuguga kwe-cylinder liner, futhi kunciphise impilo yesevisi. Uma inani eliyisisekelo lamafutha okugcoba isilinda lingakhuliswanga phakathi nale nqubo, ukugqoka kuzosheshiswa. Kulokhu, ukusetshenziswa kwezindandatho ze-cermet piston kuzothuthukisa ukumelana nokugqokwa kwendandatho ye-piston, kunciphise i-coefficient ye-friction, kunciphise kakhulu umthelela ekusebenzeni kwe-friction pair, futhi kwandise impilo yesevisi ye-piston ring kanye ne-cylinder liner.
