Can I drift the thread for a second to ask why this is - what is the mechanism, and why does it need rpm changes to work ?
Some auto engines I have worked on have oil holes in the con-rods to direct a jet of oil up into the cylinders from underneath.
Other engines I have seen have oil jets mounted at the bottom of each cylinder, spraying upwards.
