Visualization and Measurement of Oil Flow in Transparent Oil Passage of Crankshaft

Pretty flash in that they made a section of crankshaft out of transparent polymer, and not only measured the oil pressure available to the crankpin, and estimated the volume, but were able to visually detect aeration in the journal drillings with a reduction in oil pressure.
Of note is the "I" versus "V" crank drillings...it's not your Grandaddy's cross drilled crank, but there is apparent merit in it.
