In a 'Pivotal' engine the only components subject to wear are the chamber surfaces, the compression seals and the bearings. Modern surface coating technology provides a wide range of material choices making it possible to achieve the service life required in almost any engine application.
By pivoting the piston we have removed the high lubrication demand that is associated with the sliding piston of a conventional two/stroke engine (the cause of excessive oil loss out of the exhaust). Oil can be metered by the engine management system directly to the surfaces of parts where it is needed. The 'Pivotal' engine oil usage is only 10% of the level required by a conventional two/stroke engine. This rate of oil consumption is comparable with the oil consumption of a four/stroke engine before the additional saving from not having oil changes is factored in.
