Abstract
Some embodiments relate to an internal combustion engine that includes a combustion chamber and a rotating component. The internal combustion engine further includes a sensing system that detects an angular position of the rotating component. A controller calculates a ratio between air and fuel in the combustion chamber based on the detected position of the rotating component. As an example, the rotating component may be a crankshaft where the controller calculates a speed of the crankshaft and an acceleration of the crankshaft based on the detected position of the crankshaft.
