  • Freedom Motors - Moller

    2018-4-6 · • Uses a lubrication system where very small quantities of oil are metered to the roller bearings and seals. Any remaining oil then exits the engine before becoming acidic. • Can tolerate siloxanes by using chrome carbide wear surfaces and silicon nitride seals (9 Mohs versus 6-7 Mohs for silica). The rotary engine does not need or use valves.
