The GOETZE Cylinder Distortion Measurement System and the Possibilities of Reducing Cylinder Distortions

The GOETZE bore distortion measurement system “Messfix”, or “Incometer, was brought into service in 1973. The advantages of this measurement system are described, with particular emphasis on the mathematical editing of the data — an essential prerequisite for determining different influence factors and implementing carefully targeted measures.

Solutions for minimization of the bore distortion of open-deck and closed-deck engines based on years of experience are presented with the aid of examples. The characteristic distortion features of both engine designs and their causes are discussed.

Finally, possibilities of evaluating the bore distortion of an engine by way of comparison or specific tests are outlined.
