Abstract
A method for aligning cycles of an engine conditioning monitoring system includes: receiving data corresponding to a TDC angle of an engine from a crank angle sensor; receiving data from one or more accelerometers for each cylinder of the engine, the received data including vibration amplitude data; analyzing vibration amplitude data from the one or more accelerometers in relation to data corresponding to the TDC angle of the engine; characterizing vibration data using segmental band analysis, wherein segmental bands of the segmental band analysis correspond to valve closure angles of the engine; identify cylinders for which analyzed vibration amplitude data in relation to the TDC angle of the engine are out of phase; and align vibration amplitude data by shifting analyzed vibration amplitude data relative to the TDC angle of the engine such that vibration amplitude data is aligned with the TDC angle of the engine.
