Abstract
A computer-implemented method, computer program product, and computer system is described for identifying top dead center of a reciprocating piston. A piston is progressed in a first direction along a first piston stroke included in the cyclical motion, toward an expected top dead center position of the piston. A plurality of piston positions and corresponding pressure indicators are determined during the first-direction progression of the piston. The piston is progressed in a second direction along a second piston stroke included in the cyclical motion, toward the expected top dead center position of the piston. A plurality of piston positions and corresponding pressure indicators are determined during the second-direction progression of the piston. One or more symmetric aspects of the first- and second-direction data are determined, and an updated top dead center position is determined based upon, at least in part, the symmetric aspects.
