Burning Mark Test for Piston Rings with High Speed Diesel and Gasoline Engines – An Engine Test Procedure to Rate the Scuff Resistance 2008-36-0072

The burning mark test is an engine test procedure to determine the scuff resistance of the running surface of piston rings. It forms the basis to compare and rate surface treatments of ring base materials and ring coatings regarding their potential to stand high thermal loads. The tests are carried out on a High Speed Diesel engine as well as on a turbocharged Gasoline engine. The paper shows the specific details of the definition of the burning mark test, demonstrates the most important test results and gives finally a summarized rating of the burning mark resistance of the materials investigated.
