System and method for estimating ring-related parameters

A non-transitory computer-readable storage medium having computer-executable instructions stored thereupon which, when executed by a computer, cause the computer to:

• determine, for a plurality of respective piston locations within a cylinder bore, an individual three-dimensional bore distortion of the cylinder bore,
• the cylinder bore being defined by a cylinder block of an internal combustion engine, and having a cross-sectional shape and a cross-sectional size, and
• each individual bore distortion indicating the cross-sectional shape and the cross-sectional size along substantially an entire length of the cylinder bore;
• determine an estimated three-dimensional bore distortion of the cylinder bore by combining the individual bore distortions, the estimated bore distortion being indicative of differences between the cross-sectional shape and the cross-sectional size of the cylinder bore and an operational cross-sectional shape and an operational cross-sectional size of the cylinder bore during operation of the internal combustion engine;
• receive a bore distortion signal indicative of the estimated bore distortion;
• receive a static data signal indicative of static parameters related to the internal combustion engine;
• receive a dynamic data signal indicative of dynamic parameters related to operation of the internal combustion engine;
• determine at least one ring-related parameter, associated with combustion in the cylinder bore during operation of the internal combustion engine, based at least in part on the estimated bore distortion, the static parameters, or the dynamic parameters;
• determining an operational parameter of the internal combustion engine, or a second internal combustion engine, based at least in part on the at least one ring-related parameter;
• and
• controlling the internal combustion engine or the second internal combustion engine based at least in part on the operational parameter.

A system for estimating at least one ring-related parameter related to at least one piston ring during operation of an internal combustion engine, the system comprising at least one processor configured to:

• cause execution of a ring performance model configured to dynamically estimate at least one ring-related parameter related to the at least one piston ring during operation of the internal combustion engine, the ring performance model configured to:
• receive a plurality of bore distortion signals indicative of bore distortion, the plurality of bore distortion signals corresponding to movement of a piston, associated with the piston ring, between a plurality of piston locations within a cylinder bore of the internal combustion engine, the cylinder bore having a cross-sectional shape and a cross-sectional size,
• determine, based on the plurality of bore distortion signals, an individual three-dimensional bore distortion of the cylinder bore corresponding to each location of the plurality of piston locations, each individual bore distortion indicating the cross-sectional shape and the cross-sectional size along substantially an entire length of the cylinder bore,
• determine an estimated three-dimensional bore distortion of the cylinder bore by combining the individual bore distortions, the estimated bore distortion being indicative of differences between (1) the cross-sectional shape and an operational cross-sectional shape of the cylinder bore during operation of the internal combustion engine, and (2) the cross-sectional size and an operational cross-sectional size of the cylinder bore during operation of the internal combustion engine,
• receive a static data signal indicative of static parameters related to the internal combustion engine,
• receive a dynamic data signal indicative of dynamic parameters related to the operation of the internal combustion engine, and
• determine at least one ring-related parameter related to the at least one piston ring during operation of the internal combustion engine based at least in part on at least one of the estimated bore distortion, the static parameters, or the dynamic parameters;
• and
• cause execution of a bore distortion model configured to generate a first three-dimensional representation of the estimated bore distortion and a second three-dimensional representation of the cylinder bore with the cross-sectional size and the operational cross-sectional.
