Abstract
Methods and systems for operating an engine and determining relative compression ratio differences from a reference cylinder are disclosed. In one example, an engine is rotated via a starter or another type of electric machine and engine deceleration rates related to each engine cylinder are determined. The engine deceleration rates form a basis for compression ratio factors for each engine cylinder.
