Sažetak
Modern engine monitors provide vast amounts of data obtained from aircraft piston engines. Most important parameters are Cylinder Head Temperatures (CHTs) and Exhaust Gas Temperatures (EGTs) that are available for each engine cylinder. A CHT-EGT trajectory is formed from successive CHT-EGT pairs present in a CHT-EGT scatter plot. The short term CHT-EGT trajectory captures short term dynamics of engine temperatures and can be used for its visualization. By comparing temperatures of the individual cylinders, under the assumption of similarity of operating temperatures of individual cylinders in a normal engine, abnormalities in engine operation can be detected. The method based on the comparison of short term CHT-EGT trajectories can be used to detect abnormalities during dynamic engine operation. During static engine operation, the CHT-EGT trajectory should shrink to a small area, and this can also be used to detect engine abnormalities.
