A piston combustion engine design principle that avoids the strong sidewall friction of conventional combustion engines. while it requires precision engineering and is subject to thermal expansion issues, an alloy such as Invar 36% nickel in iron has exceptionally low thermal expansion and can easily make the design work without the conventional piston rings. because it is not friction based it can thus run without lubrication making the design simpler and much more energy efficient. the rocker arm will link to a crank shaft as normal.
