SYSTEM AND METHOD FOR ESTIMATING RING-RELATED PARAMETERS

A method for estimating at least one ring-related parameters related to at least one piston ring may include estimating a bore distortion of a cylinder bore. The bore distortion may include a plurality of bore distortions corresponding to a plurality of respective piston locations within the cylinder bore. The method may also include receiving the bore distortion in a ring performance model configured to dynamically estimate a plurality of ring-related parameters associated with combustion in the cylinder bore during operation of the internal combustion engine. The ring performance model may be configured to receive a static data signal indicative of static parameters and a dynamic data signal indicative of dynamic parameters related to operation of the internal combustion engine. The ring performance model may be configured to estimate at least one ring-related parameter related to at least one piston ring during operation of the internal combustion engine. 一种用于估计与至少一个活塞环相关的至少一个环相关参数的方法可以包括估计气缸孔的孔变形。该孔变形可以包括
