Abstract: The present invention provides for automatic relief of excess pressure within an engine lubrication system in such a way as to recover a significant portion of the energy that was used to create the excess oil pressure.

The impulse/momentum wheel is advantageously coupled to the engine gear train, thereby reducing the engine power required to run the gear train by recovering energy from the lubrication system.
