A new method for detecting the shape of a piston ring has been developed. The method uses the magnitude of a surface wave ultrasonic echo to plot the quality of the contact between a piston ring and a gage bore on a polar graph. The testing method and the results are discussed for single-piece and multi-piece rings, and for various surface treatments utilized in automotive piston rings.
