in an attempt to further our understanding of the pump, we measured pressure pulsations at the outlet of the pump. the spectrum of these pulsations is presented in figure 4. also shown on figure 4 are dimensions associated with the pulsation measurement. the pressure transducer was located at least 43 inches from the pump impellor.

this vents excess oil back to the sump when the maximum allowable pressure is reached. oil pressure mapping is simply a method of verifying that the oil pump pressure follows this curve. when the shape of the curve changes, it indicates a fault with the oil pump or excessive oil leakage in the engine, possibly due to bearing wear.
