Surely the same effect could be had by utilizing the magnetic sump drain plug, north pole up and a ferromagnetic inlet valve, north pole down in conjunction with a double (south) pole piston.
This would negate the possibility of 'Marzal valve overload'
Using copper piston rings in conjunction with a reverse hectically wound water jacket (in the form of an oscillating generator) to power a dry sump total loss lubricating system running on sump gunk refined into lube oil with the waste heat from the exhaust stack would also prolong the service intervals.
The oil, once passed through the crankcase and raised to a temperature sufficient to reduce it's viscosity, would be fed directly to the elevated, insulated, ready use day tank, the gravity feed to the injector pump obviating a lift pump and aiding bleeding of the system on the initial set up.
The excess power would generated be more than enough to condense water from the exhaust, in a low pressure evaporator powered by the vacuum occasioned in the induction stroke, for injection into the inlet tract to prevent overheating, and thus loss of magnetic properties in the inlet valve. The decarbonisation effect of water injection is a matter for debate and best left to another thread, should there be any interest.
With further development of the engine management system and the inexhaustible supply of WMO from the bottom end of South Africa, a self contained generator that dispenses with the need for a world wide community of old blokes in boiler suits (dungarees for those in the US of A) and cardigans with leather elbow patches, entirely, is now (almost) a reality!
