Investigation of the Lubricating Oil Management on the Piston Assembly

Setting up a Measurement Device for Tribological Studies in the Piston Assembly

“…5 setup ring gap position measurement, acc. to (1,9) The graph indicates the measured counting rate versus the piston ring angle to the anti-thrust side for both detectors. Only in the area between 40° and 130° to the anti-thrust side (ATS) there is a low precision in determining the position of the probe.…”
