In the field of tribology, floating liner tests are carried out on a single-cylinder research engine in fired operation for car engines:
Friction investigations of liner materials / coatings and ring coatings
Lubricant or additive investigations with regard to engine friction optimization
Comparison of piston geometries and crank shaft offset
The RNT method is based on the activation of components, working under the permissible limits (free handling limit). It can perform wear tests on various engine components. The activity of the worn particles in the oil circuit is measured and converted into a wear rate.
The aim of the investigation is to determine a wear rate and wear behavior over the entire service life of a component.
