Claim 9:
10. A method for controlling lubrication of a plurality of apex seals for a rotary engine, the method comprising:
generating a vibration measurement signal with a vibration sensor for a rotor including the plurality of apex seals;
monitoring the vibration measurement signal and identifying that the vibration measurement signal exceeds a first vibration threshold, monitoring the vibration measurement signal including filtering the vibration measurement signal based on a crank angle of the rotor; and
controlling lubrication of the plurality of apex seals by increasing a flow rate of a lubrication flow for the plurality of apex seals based on an identification of the vibration measurement signal exceeding the first vibration threshold.
