Abstract
A method and system for identifying a phase in an internal combustion engine (102) is disclosed. The internal combustion engine may include an even number of cylinders and is fitted with at least one sensor. In one embodiment, the method includes measuring a state of the internal combustion engine using the at least one sensor. The method may further include calculating a deviation of the state from an expected set of values, and determining the phase of the internal combustion engine, based on the deviation.
