The method comprises operating a calibration engine, and collecting combustion characteristic data and reference accelerometer signals, which are correlated with each other and stored in a calibration table. The calibration table can be used by an engine to determine a real-time normal combustion characteristic when the engine is operating by collecting a real-time accelerometer sensor signal and cross correlating with the correlated data stored in the calibration table. Accordingly, the apparatus comprises a calibration engine comprising a calibration sensor, a reference accelerometer sensor and a data storage device for storing the collected calibration data that is correlated with the collected reference accelerometer signals, and an engine equipped with an accelerometer sensor, a calibration table and an electronic engine controller programmed to receive real-time accelerometer signals and cross correlate them with reference accelerometer signals to determine a real-time normal combustion characteristic. |
